Nvidia GT 430 no sound via HDMI

[slimb]

Hey all,

I've been trying to get my new nvidia GT 430 to push sound via HDMI. it's pushing video no problem.

aplay -l shows nothing but my onboard soundcard

tmyoungjr@alpha:/var/log$ sudo aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: SB [HDA ATI SB], device 0: ALC889A Analog [ALC889A Analog]

card 0: SB [HDA ATI SB], device 1: ALC889A Digital [ALC889A Digital]
  Subdevices: 1/1

While lspci -v shows that both exist (the onboard and the NVIDIA as a sound device)

If i'm in alsamixer I see both as options, however I can't do anything with the NVIDIA (i get no controls to modify). When im in system - preferences - sound my hardware only shows the internal onboard sound.

The OS knows the NVIDIA exists for sound output but I'm lost as to where to go. Running 10.10 and running the 260 drivers for the nvidia.

Any thoughts or direction would be great!

AFAIK Your kernel modules do not recognise the device.

Check the above nvidia post thread, Stephjen Warren explains what is needed for each nvidia device type.

uname -r
shows you your kernel version.

The easiest thing to do is find updated alsa kernel modules or a later kernel.
Hardest thing to do is build the alsa kernel modules.

There is an alsa upgrade script that does everything...

[lidex]

As far as alsa modules, with the patch that enables hdmi sense, this installs with a minimum of fuss. Using a Terminal="Applications->Accessories->Terminal"
Add the ubuntu-audio-dev ppa:

sudo add-apt-repository ppa:ubuntu-audio-dev/ppa
sudo apt-get update

Now install:

sudo apt-get install linux-alsa-driver-modules-$(uname -r)

Reboot
Check your levels in alsamixer.

 alsamixer

Press <F6> to select the correct soundcard.
Press <F3> to show playback levels. <F4> selects capture levels [or use <Tab>]
Use the left/right arrow keys to select and up/down arrow keys to change levels. <M> to mute/unmute.
Go to "System ->Preferences ->Sound" and make sure the correct soundcard is default and adjust your profile on the hardware tab.
On the output tab choose the correct device.

Thanks gents, my box now recognizes the card thanks to adding the audio dev PPA and I can use it for output, but I get no sound from it yet. Close but I have more work and research to do! Any other suggestions would be great! I'm going to keep doing more reading!

Which Ubuntu version are you running (are you really still running 6.06)?

Your sound devices should have shown up in aplay -l in Maverick (but probably not Lucid) if you had most recent kernel updates. The audio ppa may make your startup sounds not work when you do update your kernel. Although, sounds should still work after X starts.

Now you just need to unmute the S/PDIF devices for HDA NVidia in alsamixer by pressing m for any that show MM so they end up as 00, figure out which one works, and add a line to a file. Try the following and substitute 1,3 with 1,7 1,8 or 1,9 until you find which works:

aplay -D plughw:1,3 /usr/share/sounds/alsa/Front_Center.wav

Mine is 1,9 so I added a line to /etc/pulse/default.pa after alsa-sink line:

#load-module module-alsa-sink
load-module module-alsa-sink device=hw:1,9

Reboot. The only odd thing it that in the Output tab of Sound Preferences you will need to select the HDA NVidia device that does NOT say HDMI to get HDMI sound. The speaker test in Sound Preferences will not work, but if you play Rythmbox, etc. you should be able to switch sound output on the fly.

Nah running 10.10 - sorry apparently I omitted it from my first post (and hadn't updated my profile in ages!!)

Once I'm home later I'll give that a try. My device(s) show up properly with aplay -l now (which is much improved). However in the output tab of sound preferences i only have one device listed for the Nvidia card (the other is the onboard soundcard).

I did go through and unmute all of the lines in alsamixer already. I'll try that config change suggestion. Thanks!

Thanks all!! The last bit of advice was what finished it up. I get sound now

I even get *some* sound in XBMC - but I have further troubleshooting to do there!

Thanks again!

[kinmad]

Thanks guys,

you also sorted out my sound problems perfectly following the instructions.

I'm a Linux newbie, but couldn't get

"
aplay -D plughw:1,3 /usr/share/sounds/alsa/Front_Center.wav
to work (issue with plughw:1,3) part, but by trial and error updating the default.pa file and finding the right combination, lo and behold sound !

Thanks again from a happy camper

[kinmad]

Hi again,

After loading up all my media, I'm also having trouble with XBMC (Ubuntu 10xx) playing sound on some media.

Did you find a fix for the same issue you mentioned?

Cheers

[kinmad]

All sorted......trial and error time, but got there
