Need full resolution HDMI audio and 2 CH optical simultaneously

Am working on an install for a customer who has a Mac Mini. He is running XBMC for all his movies. I need to run HDMI to his surround processor with full resolution audio while running the optical out in 2 channel pcm for his whole house audio. Is this possible?

As standard sound would go to one or the other output, it is possible to configure things to send sound to both at the same time, but I would strongly expect this would require both to be configured the same i.e. stereo, rather than one being stereo and the other 5.1.
To configure the Mac to send to both you need to use the Audio MIDI Setup tool in the Utilities folder.
See https://support.apple.com/kb/PH5178?locale=en_US
and How to combine multiple audio interfaces by creating an aggregate device - Apple Support
It maybe that the easiest or more practical option would be to use an AV Receiver set to output via both its stereo and HDMI ports. The Mac would then just send via HDMI to the AV Receiver which would if needed handle the conversion and splitting of the signal.

Mini-dp to vga or hdmi, need full resolution

I've HP laptop which has two ports, VGA and HDMI.
I want to connect the Apple 27: display, which has the mini-dp output to my laptop. When I purchased the display, I bought a mini-dp to hdmi adapter, and connected the display to the adapter, and connected the adapter to the laptop using a hdmi-hdmi cable. But, the image is very blurry, and I'm not getting the max resolution on the display.
Could you someone give any advice/comments? Do I need a dual link dvi-d adapter?
Thanks!

Your laptop isn't compatible with the Apple 27" monitor. There are only two possible interfaces that can be used to drive the 27" at full resolution. One is DisplayPort and the other is Dual-link DVI, neither of which your laptop has.

[SOLVED] NVidia GT240 HDMI Audio and ALSA

I have an NVidia GT240 video card with HDMI out and I cannot for the life of me get the audio working through it!
I've installed the drivers for NVidia (I've managed to load up XBMC and the video works beautifully) but when loading ALSA (aplay -l) there are no devices listed! I've disabled my onboard audio outputs just to avoid conflicts, aplay -l used to output my onboard realtek devices.
I'm not sure why the devices aren't listed anywhere, either in "aplay -l" or "aplay -L".
I'm looking to see if there's a config file somewhere where I would need to declare the device or something? The device shows up as an HD Audio Controller in lspci.

Hey Nerditup,
I managed to get my card working. Here is the thread http://bbs.archlinux.org/viewtopic.php?id=90350. Mine is the last post. Basically I had to manually build the Alsa-driver package which contains the kernel modules. No patches need or anything. I just downloaded the latest package from the Alsa site and extracted it, did a cofigure, make, make install and followed the rest of the steps posted at the start of the thread(the sound.conf file) and it worked. It would not work at all with the stock Arch package.
Hope that helps and ask if you need some more help...

[SOLVED]HDMI audio and gnome volume applet issues

Hi all,
After setting up Arch without too many problems came the real pain in the ass: HDMI audio over a Asus NVIDIA GeForce EN210....
Eventually I got everything to work with the help of the ASLA en Pulse wiki pages, but I found the last piece of the puzzle here:
http://wiki.xbmc.org/index.php?title=HO … ,_or_GT240
Maybe this is useful for others too.
The only problem I have now is that the ALSA deamon fails to load. I found this in the boot log file (/var/log/boot):
Thu Apr 12 13:54:19 2012: :: Restoring ALSA Levels [BUSY] Found hardware: "HDA-Intel" "Nvidia GPU 0b HDMI/DP" "HDA:10de000b,10de0101,00100200" "0x1043" "0x8343"
Thu Apr 12 13:54:20 2012: Hardware is initialized using a generic method
Does this mean I don't need the alsa deamon anymore? Sound still works normally after boot but a strange thing is that I can turn up and down the volume with the gnome shell volume applet but the volume of media applications like vlc do not react. Same problem with flash video's like youtube. I do hear the "blip" sound from the applet.
Does anyone have ideas how to fix this?

OT: What viewers do you need to use ALL audio and video files?

I had a lot of trouble with audio and video files on my PC. I
now have a
MacBook Pro, which is a big improvement. But I still
frequently
encounter files that I can't use. I try to open them, but
Apple doesn't
know what to do with them. For example, I often encounter
unusable
videos while perusing news websites. I also have some audio
files with
.mva or .mvw extensions that don't work.
So what viwers/players do I need to download in order to be
able to play
every audio/video file that comes my way? iTunes handles .mp3
files, and
I also have QuickTime installed. I just viewed another video
after I
installed a Flash plugin. What else do I need to install?
Thanks.

HTMLB or html - when we need full control of look and feel and events

Hi Experts,
In my requirement i need to change the look and feel of the BSP UI as per customer standards and i need to have most of my processing on client side, Please advise me whether to go for HTMLB or normal HTML. mainly i fount most of the client side events are not available in HTMLB....
Thanks in advance
Karthik

Hi Karthik,
The look and feel of the BSP Tags can be applied via Portal. If you are seeing your BSP application through a protal system, then you can develop a theme inside the portal and apply it to your BSP application. The portal theme will be automatically supported by the HTMLB tags. For more infomation on this you can search in the portal forum section, you will find a lot of post for this topic.
But if you need a complex customization of the UI controls inside the BSP application, as suggested in the previous post you should go for HTML + Javascript library.
Hope it is helpful!

Maheswaran

Need help for HDMI, USD and Ethernet example SoC for VC707

I'm developin an SoC with HDMI, USB and Ethernet interfaces.
In this USB and Ethernet interfaces are not working.
Can i get any example SoC's for above mentiones IPS.

bump ... nobody has anything helpful to post ?
Am I trying to do something that is not possible with the open source driver ? start a game in wine 32bit?
Or maybe the problem is in one of the libraries ?
I did mess around with the catalyst before, but the 2d was so bad that I decided not to even try the 3D watching a movie was impossible at a decent fps O.o
And I do believe that I removed all and re-installed Open Source libraries + drivers properly. Is there a definitive way to check ?

Is it possible to disable HDMI audio while using digital optical?

As the title says I am looking for a way to do so as it is becoming a pain to turn down the audio on the TV each time when using my aTV. My TV doesn't allow me to mute the speakers depending on the input selected (it is all or nothing).
This post is more for Apple themselves to implement into the next version of iOS that they release for the device as I have tried through the menu but to no avail.

Sadly my surround sound receiver does not have an HDMI input/output. Therefore the HDMI from the aTV runs to the TV and the digital optical to the surround sound receiver. I have coax cable connected to the TV (no need for an STB as the TV has a digital tuner) which requires the speakers to be enabled.
One would think that you wouldn't need audio through HDMI if infact you are using digital optical hence my request to allow this as a native feature through the settings of the aTV.

Move audio and video between tracks simultaneously

If I have a video clip on V1, with linked audio on A1, I would like to move them both to V2 and A2, respectively, at the same time. Is this possible? I like to work this way to easily keep track of which video goes with which audio.

There is a practical logic why one moves Audio and Video separately.
Audio does not care what track its on...but video does (layering).
Audio tracks are frequently checkerboarded ( A&B'd) to create overlaps and enable J & L Cuts to Video.
It would be too easy to overwrite audio if it chased video track for track.
You need to use track and source targeting to organise your timeline if thats your requirement.
If the Video and Audio are linked

Not working:HDMI Audio and Enlightenment17

Hi
Been searching hard to get my new install up and humming. A couple of problems are hounding me. I would be very grateful for help.
Audio via an HDMI cable out of a little Sony TV I am using as a monitor is not working. Alsamixer shows two SPDIF outputs both unmuted showing 00.
lsmod | grep '^snd' | column -t
snd_hda_codec 147506 0
snd_hwdep 6332 1 snd_hda_codec
snd_pcm 77765 1 snd_hda_codec
snd_page_alloc 7234 1 snd_pcm
snd_timer 18718 1 snd_pcm
snd 58950 4 snd_hwdep,snd_timer,snd_pcm,snd_hda_codec
Secondly:
I am using LKDM. Launching Enlightenment 17 worked initially but after I went through the setup steps it sent me back to LKDM. If I login as root and launch Enlightenment it flashes the 'almost there' screen from the end of the setup and then sends me back to LKDM. If I login as a user it just blinks and stays on LKDM. LKDE works flawlessly (except for the fact that my user desktop background will go back to default after I log out and back in, the background for root stays put and does not disappear after logging out and back in)
I absolutely adore the Arch Linux wiki and followed the install instructions for Arch Linux/LKDM/LKDE/Enlightenment closely, I just need to get these last issues solved so I can happily grind Stata all day.
Thanks for this great community

Enlightenment17 does not work again today, but it is not an issue as I think I prefer LXDE anyway.
As per audio, tried installing the official realtek driver for linux from their site, but it seemingly just made things worse. Even after using make uninstall in the directory I installed from I cannot launch alsamixer: "cannot open mixer: No such file or directory". I tried installing OSS, following the wiki's instructions but got the following when I ran "soundon"
cc1: some warnings being treated as errors
make[2]: *** [/usr/lib/oss/build/osscore.o] Error 1
make[1]: *** [_module_/usr/lib/oss/build] Error 2
make[1]: Leaving directory `/usr/src/linux-3.10.9-1-ARCH'
make: *** [default] Error 2
Relinking the OSS kernel modules failed
uninstalled OSS and unistalled alsa-lib, alsa-tools and alsa utils. Reinstalled alsa lib, tools and utils and still no luck.
Tried just about every solution that is posted and made my problem worse. Is there a way to 'refresh' the arch specific kernel without having to do a completely new install? I tried pacman -S linux and it worked but did not bring back alsamixer functionality.
Also, anyone have any inkling as to why google-chrome or chromium will not lauch after being installed from the aur and package database?
Otherwise I am getting very good performance from my hardware in the programs I use.

HDMI audio and video problems on new DV6t se

Just received my HP Dv6t laptop and i immediately upgraded to Windows 7 ultimate. I am facing two problems,
Firstly, if i disconnect and reconnect the HDMI cable the sound only comes from the speakers and not the monitor (works fine with my HP HDX16t laptop using the same hardware). I set the HDMI sound to default when the HDMI cable was connected to my monitor. But when i tried to do the same thing when its disconnected i dont see the HDMI option (i already ticked the "Show disabled/disconnected devices" tab).
Secondly, i use an ASUS monitor for work purposes and a SONY TV to watch movies. When i connect the HDMI cable to the SONY TV it underscans the image and i have to readjust it to fit the TV. Similarly if i re-adjust the image and connect the HDMI cable back to my ASUS monitor it overscans the image (because that's how i had it on the TV) and i have to fit it again. This wasn't a problem with my HP HDX16t laptop (again using the same hardware)
Any help??

Hi,
This issue happens most probably due to Corrupted Video Card Drivers.
Right click on Desktop, click Screen Resolution, set the Screen Resolution Slider to Maximum, click Apply/Ok.
Check if you are able to play Videos fine. If it does not work.
1. Click Start, type: DEVMGMT.MSC in Search Field and Press Enter. It opens Device Maanger Window.
2. Go to 'Display Adapters' category, and expand it. Right click on Display Driver entry, and click uninstall.
3. Click Start->All Programs->Recovery Manager->Click Hardware Driver installation.
Select Video Card Driver entry, and click Install.
Restart the PC, and check of the issue has fixed.
Thank You.

I need to capture streaming audio and save to a wav file

I need to be able to capture an audio stream delivered via ethernet using UDP protocol and then save to a wav file.
I currently can capture the data stream but do not know how to format the data to save it to a file. Our format is 16KS/s, 16bit, PCM, no compression.

Did you do the thing about searching in the example database. Let us use that as base for discussion. Those who put in some effort will be rewarded. Also check out the AU file format http://en.wikipedia.org/wiki/Au_file_format As it is big-endian http://en.wikipedia.org/wiki/Big-endian the numbers can be stored as is in Labview. Must players,matlab, etc can use the AU file format.
Besides which, my opinion is that Express VIs Carthage must be destroyed deleted
(Sorry no Labview "brag list" so far)

HDMI audio and Audio Out mutally exclusive now?

Hello,
I have a 2010 MBP and use an external display via HDMI as well as external speakers via the headphone jack. This worked just fine until a recent update. After a recent update, when I have my display connected via HDMI the audio out no longer works. While I am able to route sound to the display's speakers via the Sound Settings, I would much prefer to listen to sound via my Klipsch speaker system that is connected to the headphone jack.
When I remove the HDMI connection, the speaker system works fine. The moment it is plugged in, the sounds cuts out. This used to work fine?
Any body have any information on this? When I google search on this issue, all I see are people having trouble routing sound via HDMI - which is basically the opposite of my current problem. It appears as though audio is know mutally exclusive -> it can only be routed to HDMI if its connected. If it is not connected, then headphone jack works fine.
Thanks for your time.

when you did your update, it probably routed your audio through you HDMI cable which is it's main purpose since most people who coneects via HDMI doesn't hook anything to the source.
try hooking up your speakers to your display's headphone jack if you have one.
other than that, i don't know what else to tell you.
good luck...

Captivate 8 print widget does not print in landscape; prints full resolution of project and not just the certificate?

I am new to Captivate and am tasked with learning how to use Captivate 8. I need to add a certificate of completion to the end of my project and have many questions for which I cannot find any answers! Please, if anyone can answer these:
1) I do not want the certificate to be printed until the score of the quiz reaches a specific minimum - for example, you need a score of 80% or better to print a certificate. How do I do this with the print widget?
2) I want the certificate to print out without the slide background and without the project's resolution - in other words, I only want the certificate image (with added text box for name) to print, IN LANDSCAPE, without the user having to make all the adjustments on their end (choosing landscape over portrait with their printer). How is this accomplised?
3) I want a date entered on the certificate - how do I add this specific element?
Without a certificate widget and the use of Flash with this version, I am confused as to how exactly Captivate provides the ability to print certificates? I do not know HTML5, and am spotty with Javascript. Why would a feature such as certificates and the ability to print them be such a clandestine thing? No tutorials, no clear advice on how exactly to achieve this widely popular feature of training material development. Seems to me that it should be MUCH easier to accomplish, but I'm stumped at this point.

The solution I found is this:
Don't use the print widget in Captivate 8. It simply does not work the way it should be able to work. Unless you are capable of scripting in Actionscript 2.0 and have access to an older version of Captivate, there is no way to get around this bug.
The problem I discovered is that Captivate 8 will only allow you to use Actionscript 3.0 in Flash; you can open the widget in Flash, but you MUST open it through Captivate first if you intend to use it in Captivate. So, once you open the widget for adjustments through Captivate, it automatically chooses AS 3.0 as the scripting language to use, no other choice is available. IF you have Captivate 7 or lower, however, it allows you to script in AS 2.0. I do not, so I cannot assist you in scripting the widget.
What I ended up doing was, I made my own certifcate in Photoshop, saved it as a .PNG, and added it to the last page. Using the internal coding of Captivate I told the program to only go to that slide upon success of the quiz.
To Print: go to Window > Skin Editor. On the left are check boxes for playbar choices - check off 'Show Playback Control,' and then choose your theme. From the dropdown, choose "print." If you don't want anything else on the playbar, then check those items off; Choose where you want the playbar to show (I chose bottom and bottom center). See below:
You can see the icons on the bottom, in the center. The icon to the left is the Print button. This works well, though you may have to make print choices from your local print dialog. I have to tell it to print landscape, for instance, otherwise it prints portait and too small. But this does work, and it solves the issue of non-working print widgets.
