Enable audio through HDMI on GT240 - Page 7

**Stephen Warren** · 08-13-10, 10:32 AM

zim2dive,

First, you should try removing the options "enable_msi=0" and/or "probe_mask=0xffff,0xfff2" from /etc/modprobe.d/sound.conf and rebooting. The first option should now be the in-kernel default for any NVIDIA audio controller as I understand it. I believe the second option restricts the set of codecs that the driver searches for, and could possibly be knocking out your analog port on the motherboard audio controller. Note that removing this option might change the card/device/... IDs of any existing working ports.

What does "sudo aplay -L" say? What is the content of /proc/asound/cards?

Thanks.

Hi Guys,

I have an atom330 mobo with a GT 240.

VID CARD = ASUS ENGT240 Silent GeForce GT 240 550MHZ 1GB DDR3 1.58GHZ HDMI DVI
RECEIVER = Denon, AVR-3808CI ---> can play pretty much every codec out at the moment.

At this point I have minimal ubuntu 10.04 64-bit + ALSA 1.0.23 installed.
I can see NVidia HDMI devices through aplay *BUT I HAVE YET TO HEAR A SOLITARY PEEP OUT OF ANY TESTING DONE* Speaker-test and aplay all appear to work but not a single sound.

**Stephen Warren** · 09-01-10, 10:46 AM

thethirdnut,

Can you please try "hw:3" instead of "plughw:3". Also, did you try plughw:9/hw:9? Any of the four devices might map to the HDMI port you're using.

You may also wish to run "alsamixer -c 1" and ensure nothing is muted.

"speakertest -c 2" might be the simplest test, rather than aplay.

If none of that works, pleas can you please copy and attach /proc/asound/card1/codec* and /proc/asound/card1/eld*.

Thanks.

Thanks for the reply Stephen.

I will try the eld* trouble-shooting and other steps you mentioned. I have two other discussions going in ubuntuforums....will report back.

thethirdnut,

I believe you need ALSA modules with the following patch:

http://git.kernel.org/?p=linux/kerne...1cb5fbe7fc9c75

It looks like linux-backports-modules-alsa-2.6.32-24 doesn't contain this yet. For a bug related to this, see:

https://bugs.launchpad.net/ubuntu/+s...32/+bug/611810

One of the comments there recommends the following as a way to get a more up-to-date ALSA driver:

thethirdnut · 09-02-10, 12:05 PM

Thanks again Stephen.

Where I started with this is all is the ALSA Install Script http://ubuntuforums.org/showthread.php?t=1046137 and 256.44 then 256.53 all of which was covered in this guide. http://wiki.xbmc.org/index.php?title...T220,_or_GT240

The backport-modules was another attempt.

Are you saying that the install script would NOT have the patched modules?

-------------------------------------------------------

I also did try the ubuntu-audio-dev/ppa at one point too, HOWEVER, I do not think I applied the linux-alsa-driver-modules in those same steps.

I will try that out and let you know.

--------------------------------------------------------

Do I also need to modify the /etc/modprobe.d/alsa-base.conf either way?

**Stephen Warren** · 09-02-10, 12:09 PM

thethirdnut,

The ALSA install script mentioned in that ubuntuforums.org post appears to install the latest official release of ALSA. No official release includes the patch you need yet; it's only in their git repository.

thethirdnut · 09-02-10, 12:41 PM

OK, so I shall:

a) reinstall ALSA 1.0.23 through the script
b) apply the patch(es)

I could use a little assistance on how to ensure I am downloading correct patch file and applying it to proper file?

Can I wget the patch file(s) from somewhere and then use a command like this?

sudo patch -p1 -d /usr/src/Alsa-1.0.23/alsa-driver-1.0.23/sound < new.patch

Thanks

thethirdnut · 09-03-10, 12:19 AM

GOOD NEWS! I have something to report...

Long story - short = YOU HAVE TO RUN THESE TESTS WITH X RUNNING!

This HTPC is an Ubuntu minimal install -- thus I have been booting into the shell for every change made to ALSA, nvidia drivers, etc. My HTPC was/is connected to the AMP and showing login info, etc on the plasma TV too so I thought this was OK.

I have gone back-forth-back-forth 100 ways over last few days and all the while cat /proc/asound/card0/eld#* remained empty.

I also recalled seeing some HDMI specific info in the /var/log/syslog at certain points, but was never sure how/where it got there sporadically.

Anyways, saw some old Toshiba forum post about audio not working when not using the HDMI for video so I ran xinit xbmc and watched /var/log/syslog...It showed a bunch of new HDMI info, /proc/asound/card0/eld#* was no longer empty, and now sudo aplay -D plughw: tests work too!

Thanks for feedback Stephen; this was a greasy one.

**Stephen Warren** · 09-03-10, 10:35 AM

thethirdnut,

That's great news. Sorry, I didn't mention that; I'd just assumed you were testing inside X!

Did you end up using the linux-alsa-driver-modules, or ubuntu-audio-dev/ppa, or something else in the end? Thanks.

thethirdnut · 09-04-10, 04:53 PM

I was using the ALSA upgrade script + nvidia 1.95.31.

Going back to 256.53 now.

At this point I have minimal ubuntu 10.04 64-bit + ALSA 1.0.23 installed. I can see NVidia HDMI devices through aplay BUT I HAVE YET TO HEAR A SOLITARY PEEP OUT OF ANY TESTING DONE Speaker-test and aplay all appear to work but not a single sound. -------------------------------------------------- xbmc@xbmc:~$ cat /proc/asound/version Advanced Linux Sound Architecture Driver Version 1.0.23.

Any of the four devices might map to the HDMI port you're using. You may also wish to run "alsamixer -c 1" and ensure nothing is muted. "speakertest -c 2" might be the simplest test, rather than aplay. If none of that works, pleas can you please copy and attach /proc/asound/card1/codec* and /proc/asound/card1/eld*. Thanks.

Stephen Warren Moderator Join Date: Aug 2005 Posts: 1,327	Re: Enable audio through HDMI on GT240 thethirdnut, I believe you need ALSA modules with the following patch: http://git.kernel.org/?p=linux/kerne...1cb5fbe7fc9c75 It looks like linux-backports-modules-alsa-2.6.32-24 doesn't contain this yet. For a bug related to this, see: https://bugs.launchpad.net/ubuntu/+s...32/+bug/611810 One of the comments there recommends the following as a way to get a more up-to-date ALSA driver: https://wiki.ubuntu.com/Audio/Instal...aDriverModules

Stephen Warren Moderator Join Date: Aug 2005 Posts: 1,327	Re: Enable audio through HDMI on GT240 thethirdnut, The ALSA install script mentioned in that ubuntuforums.org post appears to install the latest official release of ALSA. No official release includes the patch you need yet; it's only in their git repository.

thethirdnut Registered User Join Date: Aug 2010 Posts: 7	Re: Enable audio through HDMI on GT240 OK, so I shall: a) reinstall ALSA 1.0.23 through the script b) apply the patch(es) I could use a little assistance on how to ensure I am downloading correct patch file and applying it to proper file? Can I wget the patch file(s) from somewhere and then use a command like this? sudo patch -p1 -d /usr/src/Alsa-1.0.23/alsa-driver-1.0.23/sound < new.patch Thanks

thethirdnut Registered User Join Date: Aug 2010 Posts: 7	Re: Enable audio through HDMI on GT240 GOOD NEWS! I have something to report... Long story - short = YOU HAVE TO RUN THESE TESTS WITH X RUNNING! This HTPC is an Ubuntu minimal install -- thus I have been booting into the shell for every change made to ALSA, nvidia drivers, etc. My HTPC was/is connected to the AMP and showing login info, etc on the plasma TV too so I thought this was OK. I have gone back-forth-back-forth 100 ways over last few days and all the while cat /proc/asound/card0/eld#* remained empty. I also recalled seeing some HDMI specific info in the /var/log/syslog at certain points, but was never sure how/where it got there sporadically. Anyways, saw some old Toshiba forum post about audio not working when not using the HDMI for video so I ran xinit xbmc and watched /var/log/syslog...It showed a bunch of new HDMI info, /proc/asound/card0/eld#* was no longer empty, and now sudo aplay -D plughw: tests work too! Thanks for feedback Stephen; this was a greasy one.

Sorry, I didn't mention that; I'd just assumed you were testing inside X! Did you end up using the linux-alsa-driver-modules, or ubuntu-audio-dev/ppa, or something else in the end? Thanks.
