Surround sound+ps3+pc+22" monitor

My question is: How is it possible to connect all of these devices? I have a sound blaster Z sound card with 6.1 surround sound hooked up to my computer, which is connected to my 22" monitor. Plus I have my PS3 connected to the back of my monitor but it runs off the stupid speakers on the monitor which sound crappy. I currently have the 6 speakers connected to the sound card. I'de like to run both the ps3 and the pc with surround sound and not have to unplug the speakers from the pc and to the ps3 and so on. Please help me with this issue someone. I also have a 7900 gt oc bgf nvidia graphics card if this some how also helps.

Most of those "surround" headsets only have two channels, and the "surround" sound is emulated by the driver, which I guess does not have a linux version.
This is probably the reason why you only see a stereo device - it's what it is on the the hardware level. What the linked "solution" does is, it tells pulseaudio to use 8 channels per default and enables remixing both regular channels and LFE. This leads to pulseaudio downmixing the 8 channels to 2 to match the numbers of your speakers. Essentially, this is what the windows driver should be doing, so if it sounds different, it's probably a matter of different implementation/enhancements the dolby driver includes.
Bottom line: you can't have 8 channels on a device which only has 2 channels on the hardware level. This is why I went for a Roccat Kave back then - it has 6 physical speakers, 3 on each side.

5.1 Surround Sound monitoring audio interface suggestions

I will be editing some live theatricals for Blue Ray, and want to use 5.1 Surround Sound tracks edited in Sound Track Pro. But I need an Audio Interface to be able to monitor the 6 channels of output in the editing, before I burn the Blu Rays. Does anyone have a manufacturer / model recommendation for an audio interface that will allow me to monitor this surround sound mix on my Mac?
I have speakers, and will need to get an amp, or will one of the Bose systems connect with this inrerface? And I don't need multi-channel input as much as output. I'm a newbie - your advice would be much appreciated.

I use the Focusrite Sapphire for 5.1 surround editing in Soundtrack Pro. Works very well. Very simple to set up and use. Good interface software and they keep updates posted on their website.
For monitors I use the M-Audio LX4's. You can buy them in a surround package with powered woofer. They are small but are good quality. Not sure if they are still made as I got mine a few years ago.
Good luck.
This set up gives me realtime monitoring from SP.

Surround Sound Monitoring

Hello,
I'm searching for a solution to monitor Surround sound from FCPX while editing. Is there a compatible USB Audio Interface? Or is the signal transfered as AC3 over the optical interface while editing?
There is no more information than that FCPX is capable of 5.1 editing on the FCPX-Pages.

You can use either the mini-Toslink optical interface or a USB interface. Set them up for surround in Audio MIDI Setup
For an overview of how it looks inside FCX, scroll down about halfway to "Surround Panning":

5.1 Surround sound on multiple devices problem

Ok, heres my scenario:
I recently bought a set of 5.1 surround sound speakers, for my iMac, MacBook and PS3. How would I go about connecting these devices to the speakers.
My speakers have that weird 3 cable input on the subwoofer (yellow, black and green 3.5mm sockets), and I have 3 3.5mm jack cables to go with it.
Obviously the iMac only has 1 3.5mm jack output, so how would I go about connecting this?
Then theres my Macbook Pro, again same problem, 1 3.5mm jack, but I need a way to then connect my iMac and Macbook to the speakers without having to keep switching the cables around.
Then finally theres my PS3, which is connected to a monitor via HDMI, there is not other outputs apart from a headphone jack from the monitor, and then the optical out on the back of the system (which I have never really used before).
I would not like to spend too much, but I must have all 3 of these machines connected, without having to rearrange cables every time I use a different machine.
Thanks in advance.
PS. If possible, I would also like to have en extra audio input, just incase I need to plug my iPhone in too.

What's the best way to get 5.1 surround sound on my iMac 2011?
It depends upon what you wish to do with the 5.1. Most output related uses require 3rd party software as there is no native support for 5.1 in OS X.
A Google search will find you a lot of info on the subject. Searching these communities will also find a lot of useful info.

Is it even possible to edit surround sound on a Mac Pro?!?!?!

Hello,
I've just been reading this thread:
http://discussions.apple.com/thread.jspa?messageID=2924869?
Which among many things discusses the fact that Mac Pros, even through an optical cable, are not capable of exporting live 5.1 audio - they can only playback already encoded 5.1 dolby audio from DVD's for example. Apparently the optical out is a purely stereo affair otherwise. I've finally received my Logitech 5450 speakers (took weeks and weeks) and hooked them up. They can indeed playback 5.1 from a DVD, which is splendid. However, one of the things I was most looking forward to was working on surround mixes in Soundtrack Pro. However, firstly STP doesn't want to convert stereo files into surround (like the video online showed), but only means that the surround panner pans between the two front speakers. (I know there's another thread about that, but the proposed solution of adjusting the collapse slider does nothing).
Secondly, and perhaps more confusingly, if I load an actual 5.1 file from the STP content, it still doesn't play in proper surround - the centre speaker kind of works and I think something's rumbling through the subwoofer, but both of the left speakers and right speakers are 'compressed' into the front one alone - nothing comes out of the rear speakers (they are perfectly connected I assure you!). In other words, f I move the puck in the surround panner so it's solely on the front right, and then over to the rear right, it's exactly the same (coming out the front).
I'm sure there must be a solution. Why would Apple advertise the ease with which one can now mix surround if the Mac Pro (I'm not exactly talking about a mac mini here) cannot export live 5.1?
Something which I'm sure is related, but which I can't solve, is that if I go into Audio MIDI setup in Utilities, and try and 'Configure Speakers', only two channels are recognised, and it won't let me select any of the multichannel options (such as 5.1, which is greyed out.)
Anyone know what I'm going on about? I'm totally lost - not really an audio person in general, but hoping to enrich my short films with some surround magic.
Any help greatly appreciated!

Typically 5.1 is mixed, and monitored on a 5.1 monitoring system, which means you need an audio interface and setup capable of outputting six channels of audio.
So of course the Mac Pro is capable, but not without additional multi-channel playback and monitoring hardware.
Encoded surround sound, which you hear on playback from things like a DVD, is entirely different story and the encoding is done at the end of the mixing/mastering process. Sometimes you will encode a mix in a variety of formats, Dolby Pro Logic, DTS etc.

Guide : Getting 5.1 surround sound. Audigy 2

Hi all
I thought I would write up a really quick but effecti've and simple guide for owners of the Audigy2 ZS and seeing how its Xmas time, I can assume a few lucky boys and girls may have this awesome card under the tree.
Most of whats covered should work with all creative products.
(Sorry, but I WILL NOT cover any info regarding encoding media or the like that will conflict with copyright laws)
This guide is for setting up your Creative Audigy 2 ZS for surround sound 5. reproduction and information in regards to required Filters/Codecs. I have not included any advanced set up options or the like as the ZS with the set ups I have incluced here will cover it out of the box.
One of the most common issues people may have with 5. not fuctioning correctly while playing a DVD movie ( Mpeg ) or any multi channel media that is 5. encoded, has to do with Codecs/Filters.
Most media players will not decode all AC3filters/Mpeg, thus require extra filters/codecs/plugins to be installed.
Ok , the first thing to do is ensure your sound card and speakers are set up correctly.
Most common speaker sets have 3 plugs that go in the back of your card .
EG, Logitech X-530. Pink = Front Centre.Black = Rear left and right. Green = Front left and right.
Ensure they are in the correct place and are tightly fitted.Ensure your sound card is secure and tightly in place.Make sure your speaker cables are tidy and not a big tangled mess.
Ensure in device audio controls that SPDIF passthrough is NOT ticked as this is for optical output ( the ZS pro with rack fuction )
Update to the latest drivers an media source ap
ps.
A few little things to set up first in Creative Mixer Control Panel to ensure cleaner sound:
Lower Master and Wav volume in Creative mixer to about 90% as to avoid any over dri've disstortion.Lower Master Bass Volume to about 90% to avoid over powering the bass.Ensure that your speaker settings Windows control panel and Creative speaker settings match your speaker set up..
Also run the THX Speaker Callibration test in basic mode.
YOU SHOULD DISSABLE CMSS IN EAX CP IN ORDER TO GET 5. TO FUCTION AS IT SHOULD.
CMSS is to be use only for a MONO or STEREO source/signal. It is for sending the stereo/mono signal ( left and right) to all speakers. This is not 5., mearly it is the same signal sent to all speakers to give you a more rich and vivid sound reproduction of an other wise flat source.
Turn off any EAX FX.
Things you want to do to ensure stable use:
SHUT DOWN CTHELPER:
A background task that is a plug-in manager for Creative drivers. A 3rd party manufacturer can use the CTHELPER plug-in interface to produce drivers, add-on features, and fixes that will integrate with a tighter fit with Creative?s sound drivers and utilities. Gi'ven its purpose CTHELPER would normally be classified as a "leave alone" background task. It also allows Creative speaker setup to be synchronized with Windows Control Panel speaker setting. Without it running that check box in Creative speaker setting is not functional (settings are not in sync). Unfortunately there are often problems with CTHELPER, most notably that it can use 00% of CPU time so it's best left disabled unless you REALLY need it .
Type in run "msconfig" and shut down all Creative Start up entries. Infact its proberly best to shut everything down.
NOTE: Any essentinal Software for the proper fuction of devices ,Eg: Razer mouse utils should be left on.
Simple Bios settings to help improve audio and stablity:
Dissable Pallette Snoop.ANY AND ALL shadows for devices, EG VGA BIOS and system bios should be dissabled. If you have the setting for PCI latency in your bios ( AGP boards only ) set it to 64, if its already at 64 try 32 .
Shut down ( remove, reconmended ) any 3rd party tweak apps that run in the background.
EG, Cache Man and any monitoring software.
Ok, now for Filters/Codecs and Plugins.
A major required Filter is AC3. (ac3filter__0a_rc5)
AC3Filter - it is DirectShow filter for AC3 decoding to play AVI with AC3 audio tracks and MPEG2 (DVD). Required for WMP.
NOTE: If you have DVD software that should play encoded 5. then make sure you have any updates/patches for the player installed and go through the tools/options for the player and ensure its setup correctly to decode AC3filters in the applictions tools menu.
If you use Cyberlink Power DVD you may need to pay an extra fee to get the required AC3filter/MPEG2 decoders to fuction as all 5. sound settings may be greyed out on some dated versions.
InterVideo WIN DVD ( this software suit comes with most "Asus" if not all makes of Mainboards. This suit comes complete with the required codecs/filters so get full surrport for 5. - 6. - 7. out of the box. Note: you must set it up first under audio options as it defualts to 2..
If you use WMP0 you should download and install the AC3filter or get the latest XP codec/filters packs. With out these filters you may not get 5. sound and/or poor reproduction.
Supported file types:
The following table lists the file types (formats) supported by Windows Media Player .(For files type played by Power DVD or WIN DVD please refer to the makers website or read me file for a detailed list).
File type (format) File name extension .
Music CD Playback (CD audio) .cda Audio Interchange File Format (AIFF) .aif, .aifc, and .aiff Windows Media audio and video files .asf, .asx, .wax, .wm, .wma, .wmd, .wmp, .wmv, .wmx, .wpl, and .wvx Windows audio and video files .avi and .wav Windows Media Player skins .wmz Moving Picture Experts Group (MPEG) .mpeg, .mpg, .mv, .mp2, .mpa, .mpe, .mp2v*, and .mpv2 Musical Instrument Digital Interface (MIDI) .mid, .midi, and .rmi AU (UNIX) .au and .snd MP3 .mp3 and .m3u DVD video .vob Macromedia Flash .swf Microsoft Recorded TV Show .dvr-ms*
NOTE: WMP defualts to 2.. To enable 5. run WMP0. Click on tools then point to options. Navigate to DVD then open up the advanced window. In here is everything you need to set things up.
NOTE: If you mess things up simply return to defult settings and start over.
Some common errors you may encounter with WMP.
Error messages are identified by numerical IDs, such as C00D0BC2 and 800704CF. You can determine the ID of a specific error message by clicking the More Information or Web Help button on the error message when you encounter it. The resulting page will indicate the error ID.
: Error's C00D6A and C00D9A while playing DVD's or MPEG-2 content.
This is directly related to either your current video card drivers or the MPEG-2/DVD decoder you have installed (EG: PowerDVD, Win DVD etc ). Reinstalling and/or uninstalling the MPEG-2/DVD decoder (PowerDVD, Win DVD ) and/or video drivers should fix the problem for you.
You should now be able to re-install you decoder ( Power DVD etc ) and continue its use.
Erro : C00DAC:

What are codecs Codecs/Filters.
Codec stands for Coder/Decoder. Basically it is a piece of software or a driver that adds a support for certain video/audio format for your operating system. With codec, your system recognizes the format the codec is built for and allows you to play the audio/video file (=decode) or in some cases, to change another audio/video file into that format (=(en)code).
For example, when you install Windows to your home computer, Windows installs automatically most commonly used codecs into the system, so you don't have to download them separately from their vendors. However there are some codecs that are widely used, but not installed by Windows. Most notably DivX , MPEG-2.
Get all the Codecs/Filters/Plugins you could ever need from:
http://www.free-codecs.com/AC3_Filter_download.htm (ac3filter__0a_rc5)
http://www.free-codecs.com/
NOTE: ( XviD-.0.3-2022004 for Divx ) Stand alone codec for playing Divx instead of the Divx full install.
http://www.microsoft.com/windows/win...0/default.aspx
Ok, you now should be all set.
However Codecs/Filters/Plugins are like any other kind of software installed and things can go wrong. If things are not working as they should try the following.
Download and install "Gspot"
http://gspot.headbands.com/download.htmlBuild 0307 - 23 KB Run the programme and simply point to system and select "List Codecs and other Filters"
Its a no brainer really to know whats what here and how to use it to find out the source of the issue, if you have one. If its red, its bad so you then need to trace the Filter/Codec to its source and remove it.
Here is just one very simple excample you may encounter and how it was fixed.
If you have ffdshow file is missing error pop up while running a player application, first go to C:\WINDOWS\system32 and search for ffdshow.en. Its proberly not here though. If it is just leave it be.
NOTE: ffdshow is used for AVI/Xvid enc/dec source.
To fix this "ffdshow Video Codec file is missing " error Simply uninstall your Xvid codec or your entire DivX programme, or any other Filter/Codec you have installed for playback of DivX files and AVI Video Files.
(Some times it seems a few Codecs/Filters dont get along so you must be aware of what you install).
Cheak "Gspot" again and Filter should be removed from the list.
Now you can reinstall the Xvid filter "XviD-.0.3-2022004" or your desired DivX programme.
Now go back toC:\WINDOWS\system32 and search for ffdshow.en. It should be there if it was not before. If the issue is back try a different version of required Filter.
So, thats just excample of a simple fix that got everything working again. Its not to hard to find out what the problem Codec/Filter is and then its just a case of uninstalling it. You can re-install the Codec/Filter but you should double cheak with "Gspot" and ensure the issue has not repeated itself .
If it has you can try and find out if the issue is related to another type filter causing a conflict or use an alternate Filter/Codec that will perform the same task .
Search for an updated version of required the Codec/Filter also.
Ok, thats pretty much the basics in getting correct and stable 5. sound working the way it should with your new Creative Audigy 2 ZS sound card.
I hope this has been of help.
Regards,xmn.

Sound no longer playing through Surround Sound via TV

I have had my Mac Mini for about a year now and recently purchased a new 3D LG TV. Prior to that I had another LG hooked up through it and have a Panasonic surround sound system set up with I believe it's a Gefen digital to analog converter, because unfortunately LG only makes digital and alls that is available is analog through my surround sound. I have always been able to listen to my computer through the surround sound, however, since I purchased this new TV I have not been able to. The sound plays through the TV speaker but will not play through the surround sound yet when I change inputs over to my PS3 or DirecTv I can hear everything else except my computer. This is why I am convinced it is the computer and not the TV. I don't know if I'm missing a setting or something needed to change for this type of TV or what. I am pretty technical when it comes to electronics so I have tried changing all different types of settings and played around trying to fix this but so far no luck so who has an idea or ever heard of this before?

@mndwgz and Lousyfool
Sorry for the delay, however, I was out of town and just getting back to this issue. I'm not 100% positive but I'm pretty sure that it has something to do with the computer settings or something of the sort because like I said prior to me switching tv's it has worked no problem, both of which were connected the same exact way. Both LG tv's only have an optical digital output port on it while my Panasonic surround sound only has an A/V input. To solve this I have a Gefen Digital to Analog converter in between the connection from the TV and the Surround Sound, so my computer is not connected anything in between the computer and HDMI connection to TV. Sound comes out of the TV through the computer but will not bypass through the TV to the Surround Sound. However I know it's not the TV settings because my PS3 regardless of the HDMI input plays sound through and over all my speakers. I have not tried rerunning my computer through the old LG LCD tv connect the surround sound as well to see if it worked because all the way up until I switched to an LED tv, it had. It's weird how this is a problem but have tried switching settings, changing inputs, problemsolving etc. but just don't see how my PS3 is converted through the tv to the converter to the surround sound and my mac mini is not!
Old LCD TV- LG model 42LH30
New LED TV- LG model 47LM6200
Surround Sound- Panasonic model SA-PT950
Converter- Gefen Digital to Analog Converter

5.1 Surround Speakers and TV/NTSC Monitor connection

I have a Dual 2.0 G5 that's a few years old but has an optical audio jack. I'm going to be editing a movie soon and would like to know if anyone could suggest a 5.1 Surround Sound speaker system that I would be able to connect to the computer. I've found several in the $200 range that claim they are PC speaker systems, but they seem to only have RCA connectors.
I also need to find some way to connect a TV/NTSC monitor to the computer, if anyone knows anything about that, too. I have a SONY digital-to-analog converter box, but it doesn't seem compatible with FCP (it works with iMovie).
I'm also going to post this in the G5 forum.
Thanks in advance.
Lloyd

there are many gaming speakers in the 100.00 range that work. Best Buy has them... However, you'll need a sound card to process the 5.1 sound to each speaker. You'll also have to set up Final Cut Pro for each speaker. As far as TV... i got HDMI cable with a PC connector on one end. Hooked up the HDMI to the TV.. PC connector to the mac with an adaptor... and I could play the movies on the TV. Pretty simple solution.

Surround sound not working on headset

I have the Corsair Vengeance 2000 wireless 7.1 headset for 3 years now.
In Windows I had some driver issues and in Linux I never really bothered and forgot about it.
So this headset supports surround sound, it's even in the product name, but Linux won't output it.
PulseAudio shows the following entries for the headset:
- Digital Output (S/PDIF) Vengeance 2000
- Analog Output Vengeance 2000
Both of these only show the "Balance" slider, and a greyed out/disabled "Fade" and "Subwoofer" channel. When testing, it only shows left and right channels to test.
Alsamixer only shows a "PCM" channel of which I can change volume, but nothing else. From what I understand it should show all 8 channels that come with 7.1 surround.
It also says the chip is "USB Mixer".
pamixer --list-sources
2 "alsa_input.usb-Corsair_Vengeance_2000-00-V2000.analog-mono" "Vengeance 2000 Analog Mono"
10 "alsa_output.usb-Corsair_Vengeance_2000-00-V2000.iec958-stereo.monitor" "Monitor of Vengeance 2000 Digital Stereo (IEC958)"
By some Googling I found this, but sadly it didn't help.
So it seems Alsa is not recognizing the headset as 7.1 surround capable. How can I fix this?

Most of those "surround" headsets only have two channels, and the "surround" sound is emulated by the driver, which I guess does not have a linux version.
This is probably the reason why you only see a stereo device - it's what it is on the the hardware level. What the linked "solution" does is, it tells pulseaudio to use 8 channels per default and enables remixing both regular channels and LFE. This leads to pulseaudio downmixing the 8 channels to 2 to match the numbers of your speakers. Essentially, this is what the windows driver should be doing, so if it sounds different, it's probably a matter of different implementation/enhancements the dolby driver includes.
Bottom line: you can't have 8 channels on a device which only has 2 channels on the hardware level. This is why I went for a Roccat Kave back then - it has 6 physical speakers, 3 on each side.

Blu ray and surround sound

I just purchased a Sony Bravia kdl-52v4100 and a ps3 to watch blu ray. Now I want to buy a surround sound but watch blu ray at the same time with out buying a blu ray dvd player. Is there any way I can connect my PS3 with the surround sound to play together.

Assuming you don't already have a surround system, and plan to use the PS3 for DVD and Blu-Ray playback:
1) Buy surround system with an optical audio input. Most have this. Since you have a PS3 you don't need one of the ones that has a built-in DVD player. I'm partial to the Yamaha HTIB (Home Theater in a Box) systems.
2) Buy optical audio (TOSLINK) cable
3) Connect TOSLINK cable from PS3 to surround receiver
4) Leave existing video connection between PS3 and TV in place
No need for a separate DVD player, the PS3 handles this.
You will have to change some options of the PS3 to enable the optical audio output. I can't help you here as I don't own a PS3.

Surround Sound Question

what is the best surround sound system w/ towers and that will support xbox 360, ps3 and tv all at the same time, and for the best price

Hey themarine472,
Honestly, the answer to your question is really dependent on what you’re looking for in a home theater system. Before anything else, you may want to ask yourself the following things:
1)    How many speakers do I want?
2)    What kind of connections do I need?
3)    Do I need an upconvert DVD player?
4)    Do I have a brand preference?
For starters, you’ll probably find that most common home theater system configurations will consist of two front channel speakers, two surround speakers, one center channel speaker and one subwoofer. Other configurations do exist, but the difference in price between four, six and eight-speaker systems can often prove to be quite significant. On the other hand, you aren’t necessarily limited to buying bundled packages. Most retailers, including Best Buy®, will sell individual components so that you can pick and mix your speakers. Keep in mind though that there is a trade-off for being able to do this: purchasing individual components often proves to be much more expensive than buying pre-packaged bundles.
Next, you’ll need to know what kinds of cables are used to connect your video game consoles to your TV. Most newer video game consoles will make connections for audio signals using digital optical or HDMI cables, but it’s recommended to double-check yours just to be safe. Once you know the cable types, you’ll probably want to look for a home theater system that has the same kind of inputs. For example: if you want to use HDMI cables to connect both your PS3 and Xbox 360 to your TV, the receiver should have at least two HDMI inputs.
Then the question becomes whether you should purchase a system with an upconvert DVD player. A good number of home theater bundles will include one of these players, which is great if you have an HDTV and want to watch older movies in a higher resolution. The downside however, is that whenever the player itself (or one of your speakers) needs repairs, you may find yourself packing your entire home theater back up – speakers, receiver, DVD player and all – just to obtain service.
Last, but not least, having a brand preference may be able to help you guide your purchase. After all, if everything else in your home is one brand, it might make sense to start by looking at the home theater systems offered by that same company. Many manufacturers even offer features that enable several devices of theirs to be operated simultaneously using your TV remote, as long as they are connected using HDMI cables.
While I can’t make any specific brand recommendations myself, one of the other forum users may be able to give you some feedback regarding a model that they purchased.

5.1 Surround Sound Audio Set Up

I am currently running Final Cut Pro 6. I am looking into configuring my setup to do play out 5.1 surround sound from the system. What is the best configuration to do that? Through the optical port into a DTS converter or through another external box? Thank you in advance for any help.

Final Cut Pro doesn't technically support 5.1. Soundtrack Pro & DVD Studio Pro do, but not FCP.
The workaround?
Get a capture card that supports at least 6 discreet analog audio outputs.
Setup your sequence for 6 outputs.
Route 6 audio tracks of your sequence to each of the 6 outputs.
Connect a powered monitor to each of the 6 capture card outputs (5 plus 1 sub).
Drop the appropriate audio onto the matching channel's track in FCP.
Probably not the answer you were hoping for.

Learning Surround Sound...

Hi,
I will soon be buying Logic Studio. I have never really done much in terms of Surround Sound mixing, but I would like to take full advantage of the Surround Sound capabilities Logic Pro 8 has to offer.
Does anyone know of any good online forums which will be a good learning aid?
Another thing to mention is hardware - I have a Mac Pro, but I currently use the built-in audio interfaces. I presume for the 5.1 output capabilities I would have to get hold of the hardware for it. Any suggestions on where to start for this type of thing? Does not have to be extravagant!
Thanks,
Steve

Hi,
Thanks for the info. Wow, $3K is quite a lot! Is there anything cheaper available? It isn't for pro use, but more for lesiure use. I do stereo mixing for more professional needs, and for that I have my two monitors. But the surround sound mixing would only be for lesiure - and to learn, so they would not have to be super accurate or anything.
I will check out the Dolby website too. What is there available in terms of soundcards that support surround sound? Again, nothing too fancy as I have quite a tight budget to work with!
Thanks,
Steve

How can I get surround sound to export through the correct speakers?

Hello there!
I am experienced with Soundtrack Pro and can successfully export 5.1 surround.
I'm moving over to Logic Pro to try out 7.1 surround, but I can't even export 5.1 surround successfully since dialogue for example comes out of all speakers, yet I've panned it to the front centre speaker. Please note I do not have surround speakers set up with my computer as whenever I do connect to my amplifier it just does everything through all speakers (whether using Soundtrack Pro or Logic Pro). I am using the visual surround panner as my guide. Either way the surround export in Logic Pro is not what I'm doing within the pogram.
I believe I've got everything set up properly:
In Preferences-Audio-Devices-Core Audio I have device Sunflower (16ch)
In Preferences-Audio-Output- I have 5.1 (ITU 775) or 7.1 (3/4.1)
All tracks are set with the surround panner and I can use just like in Soundtrack Pro.
I can bounce the individual stems properly.
It's just not in proper surround sound.
Where am I going wrong?
Thanks in advance.

EMB -
What is the function of Sunflower in your work flow? Usually its used to route audio between programs. In the case of Logic, you simply need to route to the outputs for things to work right.
I guess we should start with your interface - do you have 6 actual separate outputs that you can use to monitor your surround sound?
(NOTE: I no longer do surround, but used to). In my case, I used a RME Fireface 800 which had a bunch of analog outs. I used outputs 1&2 as L&R, 3&4 as Center/Sub, and 5&6 as Rs/Ls. Each of these outputs was connected to a monitor so that I could mix in surround.
When you say you are bouncing 5.1 successfully, do you mean it is creating 6 separate files?
BTW - what mechanism are you using to playback your surround files? I used to use a PC program to burn DVDA's, which I then played back on a DVDA-capable disk player.
If you are looking to encode the files so that they will playback on a traditional surround sound system, you would need to put them through a Dolby Digital encoder. If you have had Logic for a few years, you MAY have Compressor which can do this. Otherwise, Dolby Digital encoder software can be somewhat expensive.

Change Default Surround Sound Audio Mapping

Anyone know if there is a way to change the default surround sound audio mapping in Premiere CS6?
For example, when working with six mono channels being sent to a 5.1 submix. I manually set where each of the six go (front left, front right, center, lfe, rear left, rear right). Then I route that 5.1 submix to go to a stereo submix so that I can hear the downmixed audio in my laptop speakers. When my project is exported to a video file, I turn off the last step of routing the 5.1 submix to the stereo submix, so the file has all six channels of audio in their proper place. When I change the 5.1 submix to feed the master output, I get the option to re-select where each surround element should end up in the master output. In our production facility, we have surround in the order I mentioned previously. I noticed that Premiere has the front, then rears, and then center and lfe listed. It is annoying to have to re-select my surround preferences everytime I switch between monitoring the stereo downmix and the surround output.
Any way to change what Premiere sees as the proper order for surround sound channels? I know there's the audio option to change mapping, but when working on a laptop, you only get the left and right speaker, no surround settings there.

that's tied into our entire facility audio spec, and every video file we have would have to change audio mapping, in addition to re-wiring a lot of air-chain devices.
In broadcasting, it seems like it's more common to do surround sound the way we're doing it: L, R, C, LFE, Ls, Rs. I understand why some might want to do it another way, which is why it would be nice to be able to change it and leave it a certain way. I know I can submit a feature request, I'm just trying to find out if anyone knows how to do it already.
