5.1 Surround Sound from 2ch audio

I have my MacBook Pro (Late 2011) connected to a home theatre system with HDMI.
If I play a 5.1 surround movie, sound comes from every speaker as you'd expect.
But if I play any music in iTunes 11, it only comes from the subwoofer, and the front left and right speakers.
Is there any way to get sound to come from the back and center speakers...?

If the Movie has only a 2 channel stereo track then no you can't. There needs to be a 6 channel track sometimes called Dolby 5.1
You can convert 5.1 down to 2 ch but not the other way around

Mac mini 2014 won't do 5.1 surround sound from HDMI port

I can't seem to get my Mac mini 2014 to do 5.1 surround sound from the built-in HDMI port to my home theatre system. When I run the Audio MIDI Setup program the only option is 2ch-24bit (stereo). Now I didn't have this issue when I tested it with a Mac mini 2012 running 10.9.5. It allow me to select 6ch-24bit (5.1) and Encoded Digital Audio. I also don't have an issue with the Mac mini 2014 if I use a Belkin Mini DisplayPort to HDMI Adapter connected to one of the Thunderbolt 2 ports. It does 5.1 surround sound just fine. So is there something wrong with the built-in HDMI port on the Mac mini 2014 or OS X 10.10?

Outputting 5.1 Channel Surround Sound from your Mac

How to output 5.1 Channel Surround Sound from you Mac...

I have been using my MacBook Pro via HDMI into my pioneer av amp which is set up for 5.1.
I have been able to output 5.1 audio with Logic Pro and FCPX no issues at all after you setup the audio midi utility for 5.1. This setup is via PCM 5.1 audio not to be confused with Dolby 5.1.
It works great. If you want to play your edited exported movies from Final Cut Pro x in surround then it gets a bit tricky. I export the movie with FCPX as master video with the 5.1 audio then use HandBreak set to atv3 to encode / compress the video. This is great because handbreak folds the 5.1 into a stereo AAC track and also encodes the 5.1 mix into Dolby 5.1 AC3 track so both stereo and surround tracks are embedded in the movie file. So if you have an Apple TV it will play the movie with its surround track. If you play the same HandBreak compressed movie out of your Mac via hdmi to your surround amp it will only play the stereo track if you are using iTunes or QuickTime and I believe this is because of copy protect and Dolby license issues. iTunes will play a purchased movie from the itunes store in surround via your Macs hdmi to receiver setup but will only play the stereo track of the movie you exported from HandBreak even though it is set up just like an iTunes movie. To get your HandBreak movie to play in Dolby surround from your Mac all you need is VLC player, then you have to go in and select the Dolby track and the output in VLCs audio settings and bingo your HandBreaked movie then plays out of your Mac in Dolby surround. Once you set your Mac up for 5.1 mixing your amp will show your outputting 5.1 via the mac but again this is PCM audio 5.1 and apps like FCPX, Soundtrack Pro, Logic Pro will work.

HT1454 i connect my iPad to my tv with hdmi cable but the surround sound from the receiver is not working why is this?

i want to play my ipad on through my tv and receiver to get surround sound (not using the tv speakers) I connect the htmi cable to my tv and ipad do i need more cable to get my surround sound to play the audio? i thought hdmi did it all.

if you have a 6th or 7th gen classic, you'll have a have the video out cable from apple. only the 5th gen will play with a generic 3 connector video out cable.

How do I create surround sound 5.1 audio in Premiere Elements 10?

Okay, that's my question.
I have a Zoom H2n which captures two stereo channels from its 5 microphones and it creates a pair of stereo audio files. I would like to import them into Premiere Elements 10 on my Mac (OS X Lion on a desktop Mac), create a video and export the video and audio to a DVD with surround sound.
Is this possible? I have a 5.1 video camera, and the sound from that is exported correctly to DVD, so I know Premiere Elements handles existing 5.1 sound correctly.

> please report your success
Confident, aren't we? :->
Audacity would import the sound from the .mts files that my Canon saves video and surround sound to, but Audacity couldn't play the sound. It was there in the waveforms, but just a click came out. C'est la vie. I just went directly to my H2n files, and it works fine with them.
I shoot a video using a regular mic, and I also record the sound externally to my Zoom H2n. I use a finger snap or clap as my clapper board. I have the H2n set to 4 Channel, which means it records two stereo audio streams, one with a name ending in MS.WAV, and the other ending XY.WAV. I use the MS stream as my front, and the XY as the surround. I also make sure the H2n is recording at 48000.
I copy the two .WAV files to my Mac. I copy the video to my Mac.
The current version of Audacity is 1.3.14, which I used. Other versions may vary in how to set them up. You'll need current versions of LAME and FFmpeg, and Audacity directs you to the correct locations to download and install them, if you need to. Then you follow the directions to tell Audacity where to find the files; when all is correct, Audacity displays the version numbers instead of asking you where they are.
In the OS X version of Audacity, go to File -> Import -> Audio ... and locate the MS and XY files. Select them both by command clicking them, then select Open. I get two warning dialogue boxes about working on original files, so I work on copies, click OK both times. Audacity then shows its main window with two files, each having 2 tracks of audio. I do no processing in Audacity, but you may choose to if you wish.
I select File -> Export and in the resulting dialogue box I choose as my format AC3 files (FFmpeg). Choose a file name in the Save As box, then click Save.
Now is the hard part. I get a window for Advanced Mixing Options. Because I have four streams of sound, the window defaults to four channels. However, I need six channels, so I slide the slider over to get the six. For my Mac and Audacity versions,
   Channel 1 is left front
   Channel 2 is right front
   Channel 3 is center
   Channel 4 is low frequency effects (LFE)
   Channel 5 is left surround
   Channel 6 is right surround
By clicking the boxes you connect or disconnect MS left to Channel 1, MS right to Channel 2, XY left to Channel 5, and XY right to Channel 6. Then I click to OK button, and Audacity writes the .ac3 file with the name I gave it.
Start up Adobe Premiere Elements; I'm using 10, and I use the timeline. I import the video file and the .ac3 file. I double-click the video and shorten it to the first useable snap. Then I double click the .ac3 file and do the same.
I drag the video to the timeline and play it just o make sure it's where I want it and to watch the waveforms from the audio portion. Then I drag the audio to the narration track and sync its snap to the snap on the video's soundtrack. If I remembered to record at 48000, all is in perfect sync.
Right-click the video and select Unlink video and audio. Then select only the audio track that is with the video and delete it. Then select the video and .ac3 tracks and link them. Export to DVD, and I get a 4-channel surround sound with the video.
I understand from Audacity forums that the assignments of the various channels to left, right, center, and LFE have changed between versions. Be aware the assignments may not be correctly reported here and that they may change with later versions of Audacity.
Audacity is free, and so are LAME and FFmpeg. Audacity lives here: http://audacity.sourceforge.net/ and its wiki is here: http://wiki.audacityteam.org/wiki/Audacity_Wiki_Home_Page

Can't get Surround Sound from a stereo sound file

I have tried multiple times to get the surround panner to work on any of the stereo clips that are included with STP2, but it stays in stereo. If I put the surround panner all the way to anything but the left or right channel I get NO sound. Surround sound is working fine for clips that are 5.1.
Anyone have any clues as to why this is not working?
If I pick a audio clip that is surround, the panning works and sounds fine. But looking at the demo movie on Apples website, it should be no problem to put a stereo file into any of the surround speakers.
I got a new HD coming and I am going to install everything fresh.. OS and all and see if that fixes things.

I'm not sure if this helps because I new to this having only picked up Soundtrack Pro for the first time a couple of weeks ago, but I was having the same problem until I moved the widner on the Surround sound HUD to full (fully to the right). Suddenly my stereo went into all 5 channels! (I'm trying to make 5.1 from stereo at the moment) Now I could move the puck and the sound would go to that speaker. But yeah... it's something i don't see in the manual and had to figure out for myself. Only took two weeks...

I get no 5.1 surround sound from apple tv2 for any media

I have apple tv2 and think its great. However I have it connected to my ken wood surround sound system and only get sound from 2 speakers for all media including movies, netflix, my iTunes library and airplay from my iPhone or ipad.
There is no problem with connections and the same fibre optic cable supports 5.1 in the same port of my ken wood when it it connected to my DVD player.
My Dolby in settings is set to on.
Any suggestions

You really need to specify exactly what imac you have. Current ones I believe have an optical (out) and in and I think that can be combined with usb to produce multi-channel sound. But it's just an academic exercise if you don't have the optical.
Also, google "5.1 audio on imac" for lots of hits on this topic.

True 5.1 surround sound from headphone port over a Toslink cable?

http://support.apple.com/kb/SP690 page regarding the headphone port simply says: "Support for audio line out (digital/analog)". So, in planning a purchase I have the following 2 questions:
1. Does the newly released 15" MacBook Pro w/ Retina display have the ability to output true 5.1 surround sound or is it only able to output simulated surround sound? In other words, does the newest MacBook Pro decode the 5.1 signal (separate outputs front center, fronts, rears and subwoofer) over a Toslink cable pluged into the side headphone jack?
2. Using the above confuguration will the new MacBook Pro be able to play true 5.1 surround sound on HD movies purchased or rented from iTunes?

Probably: http://osx411.com/index.php?/topic/38-hook-your-macbook-pro-up-to-your-surround- system/

5.1 Surround sound from iMac.

Hi, I am wanting to change from a desktop PC (with Soundblaster card and Altec lansing 6 speaker surround sound (audio out from PC are FrontL-R, RearL-R, Centre/Subwoofer) to an iMac. Presumably I would use the firewire output (?) into some sort of adapter to create the audio signals descrbed earlier to feed into the Altec Lansing system.
I have seen old postings on the internet referring to a Griffin Firewave device but this no longer weems to be available.
Can anyone suggest how I might be able to do this. To buy a whole new home cinema system seems an expensive solution as the PC is only used in the home study.

NO surround Sound from HDMI

Hello:
I have an old HP G70 latop running Vista 32 bit. I have it hooked up to my system through HDMI to my Yamaha receiver. the video display is stunning but I am only getting 2 channel stereo adio. This reciever decodes surround sound even if there isnt any coming in...I know this because thet last computer was hooked up with audio only through the headphone jack and it worked great. I have surround sound through any other format so it is not he reciever. I have read through many posts but have not been able to solve the issue...here is what I have tried:
made sure the playback sound check is on HDMI
made sure it had dolby and DTS as supportede formats and tried every different sample rate
made sure 5.1 is checked
even did the test and got sound out of all individual speakers
tried other settings as well, quad, stereo, 7.1
tried updating driver but it says there are no updates
tried forcing an install of the realtek driver that is reference many times...wouldnt accept it.
tried deleting the driver from device mgr and reinstalling
tried different media players, windows media center, vlc and media player classic
in short...I've tried!!
the only thing I cant seem to accomplish: i see reference to check the "SPDIF" box but theat does not seem to be visable in the driver I have.
any thoughts??

Surround sound from Panasonic TM900 in to FCP X?

Just bought a Panasonic TM900 and I've been having a little play. AVCHD files (but not 1080-50p) are recognised by FCP X, and can be imported using the 'Import from Camera' function. All seems well except for the fact that FCP X reports that these have 2-channel stereo audio rather than the 5.1 surround sound that the camera records in. I have imported some of the 1080-50p files via ClipWrap and FCP X reports that these have 5.1 surround audio.
If I play both types of file (the regular AVCHD and the 1080-50p) in the VLC Player it reports that both types have 5.1 surround sound (AC3).
Why am I only getting 2-channel audio for the regular AVCHD files that I import from the camera directly in to FCP X? Any ideas?

yeah, luckily i am working with single long clips so i don't have to do it that often. it's a lot of work, true, but it does work and so far it's the only solution i've found.
i do find it a bit strange that apple doesn't let you "optimise" the audio in the same way as for video. Meaning, to convert ac-3 into whatever format it wants to edit audio in. in can encode ac3 during export, so why not decode it on import?
There's a section in the help manual that says you can specify mono channels to specific surround channels, but i've never been able to get it work, but now that i reread it, it does say to do it in the timeline. I've always tried it in the event browser. So it might be worth trying in your case.
You need to first have the configuration be 6 mono channels. Then, supposedly, you can specify each mono channel to be a surround channel.
Select the clip in the Timeline.
In the Channel Configuration section of the Audio inspector, choose an option from the Channels pop-up menu.
To assign a mono channel to a specific surround channel: Select the mono channel waveform, and choose a surround channel from the Channels pop-up menu.

How can I get true 5.1 surround sound from my iMac?

Thanks,

No sound from RealTek audio card? [Solved]

I can't hear any sound from my laptop. This is what I executed:
pacman -S alsa-utils
gpasswd -a yourusername audio
alsamixer
aplay /usr/share/sounds/alsa/Front_Center.wav
alsactl store
nano /etc/rc.conf
DAEMONS=(syslog-ng network crond alsa)
Last edited by Zdravko (2008-04-22 12:36:38)

If I understand you correctly, you have installed all required alsa packages and tried to configure. What doesn't work is attempting to push up the volume via alsamixer/aumix etc., unmuting also does not work.
Am I correct?
If so, you may have a similar issue to what happened to me a ways back. Is your current kernel up to date? The problem I had involved the fact that my sound card (though it was extremely common and, well, sh*tty) was affected by a feature regression in the ALSA code and an incompatibility with kernel in what was then [current]. I had to wait for the kernel to catch up to ALSA to do anything, but the regression had to be fixed before I could do anything useful.
Moral of the story (also known as the 'tl;dr' or 'too long; didn't read' version) - Try updating your kernel if all else has failed. If nothing useful comes out of that, try searching the ALSA site.

No sound from rear audio out port?

Hey guys.
I am trying to troubleshoot a sound issue with a Vista Home Basic machine.
I can't really give you all the MOBO specs etc because I am not currently in front of the machine. I can however confirm that it is using a Realtek chipset and is configured using the Realtek Sound Manager software.
I am really just wanting to use basic sound (i.e. just speaker, not 5., 7. etc).
I am trying to make use of an old stereo system by using a 3.5mm aux jack to dual RCA (white and red) plugs.
I can get sound when I plug the aux jack into the front earphones port but I cannot get sound when I try and use the analogue audio out (lime green) port at the rear of the machine. Vista states that it is working correctly and has a tick next to the speakers but no sound is produced by the speakers.
The MOBO has the following available audio connectors:
Analogue = Mic in (Pink) Audio in (light blue) Audio out (lime green)
Centre Speaker (Orange) Rear Surround (Black) Mid Surround (Grey)
Digital = x SPDIF
You may ask at this point, why not just use the front headphones jack? Well, the problem is that it seems to be very sensiti've in that Vista keeps reporting that the jack is cycling between a connected and disconnected state.
I also cannot use the SPDIF, as the old stereo only supports aux left and right RCA.
Also, when I try and get one of the rear ports to work, I have made sure that nothing is connected to the sound ports at the front as I know that this can cause problems.
When I plug in the 3.5mm jack into the green port, the Realtek sound manager kicks in and says that "a jack as been connected". I then confirm that I have infact connected the jack to the rear audio out port. I then follow the steps in the wizard but am not able to get sound.
I made sure that I used the most basic settings (i.e. speakers and not 5. etc).
I even tried the grey, black and orange ports (even though I know they are used for surround sound setups) and still no luck.
One interesting setting I did notice was that in Winamp, I had to select the "allow mono speaker" setting to have it play sound through the front headphones port.
However, when I was configuring the rear green port in the Realtex Sound Manager software, there was no mono option. There was only stereo, 5., 7. and some quad....... thing.
Any ideas guys on how to get the rear green port working?
I am wondering if it has something to with a connector on the MOBO. But as I said, Vista and Realtek manager seem to report that all is well.
My thanks in advance.

Record sound from M-Audio Firewire Solo input with S/PDIF

Hey there, I am using a m-audio firewire solo and connect it to my mac mini 2013 with firewire cable. If I try to record sound from my guitar, it is ok, however the sound from S/PDIF input cannot be recorded. I can see the sound signal from the mac input preference, however it just cannot be played or recorded. I have searched through the forum and found some people also have the same problem but just cannot solve it. Does anyone have some idea? Thanks.

Have you selected the correct Input pair in a stereo Logic channel strip? Standard s/pdif is a stereo signal.
Also, the M-Audio device may have to be set to slave mode as the incoming digital signal will have to become the master digital clock for the M-Audio unit.
The M-Audio unit should probably be set to 48kHz, it's doesn't do 96hHz does it?
