Howto: working GT2XX HDMI audio out with alsa

Any updates out there for getting the audio on slightly older nVidia cards (a 9300 in my case) fully working again in Lucid Lynx?

Wow, all of a sudden people started posting here again. I've just gone through and did some wiki-maintenance, noting that the drivers are also included with the latest kernel release, and removing most of the ALSA installation section which no longer applies (as no patching is necessary).

@Kode: You probably want the nV News forum for the green line problem. For the audio, try the following sound.conf:

options snd-hda-intel enable_msi=0 index=1 probe_mask=0xffff,0xfff2

The probe_mask is what tells the driver that there's only one real codec on the audio chip, not four. The index option just forces the driver to take a particular card # in ALSA. With their powers combined...

paoleary: Thanks for the advice, using custom for audio and passthrrough and setting it to plughw:0,7 has worked for me. If i added the probe_mask stuff (which, incidentally, i have done before, can't remember what it did in my case though) could i then just use NVidia HDA HDMI (or whatever it is) rather than setting the custom one?

The green thing is a known problem with displaying SD content on feature set c graphics cards, its been in trac for 5 months http://trac.xbmc.org/ticket/8337

Woo! Total success with my 9300. Here are the full details:

Lucid Lynx, latest public version of XBMC, Zotac GF9300 D-E.

aplay -l:

/etc/modprobe.d/sound.conf

/etc/asound.conf

Audio devices in XBMC were set to "plughw:0,3". I get full DD and DTS through HDMI and everything looks like it's working perfectly. I was getting audio before, but it was only able to do 2 channels in analog mode (both in XBMC and using 'speaker-test -c6); adding the sound.conf line completely solved the problem.

A mention in the Wiki would probably be worthwhile. Trying this was my last resort and I'm so glad it worked!

Huh, I was under the impression that the 9300, et al., were supported w/o further configuration. Feel free to add your knowledge to the wiki page, though the title might need to be changed. Maybe, "HOW-TO set up integrated (native) nVidia HDMI audio"?

My personal experience is that it worked fine in Karmic, but the upgrade to Lucid and the 190.x nVidia drivers broke multi-channel audio. I've been trying to get DD/DTS over HDMI working again for the last week or so, and this is what finally got it functional again.

This nV News forum thread will probably like to hear from you, too.

This is weird!

When I try to create a sound.conf file in /etc/modprobe.d with the line from pfranzen and I reboot, the system cannot recognize my sound card anymore (Zotac with 9400M).

pfranzen, do you have anything else in that configuration file (sound.conf) or just that options line? Do you get white noise in every speakers when you run speaker-test -Dhdmi -c6? What version of the nvidia driver?

The issue is that we have DD and DTS working with Lucid and latest XBMC PPA but we cannot get multi-channels pcm output. The problem starts when you try to playback a True-HD audio track...

Anybody else who got a Zotac (or Revo) working with Lucid and multi-channel pcm with latest nvidia drivers?

Hi Everyone,

I just picked up an Asus 210 based card and I am trying to get HDMI audio working as well.

My problem at the moment is that Alsa is reporting no controls for this device. I a musing Arch Linux like a few others here. I just did a full system update and I have the following versions:


Do I need to manually make the module as described earlier in the thread with the patch? I thought not according to the wiki. Arch isn't loading the snd-hda-codec-nvhdmi on it's own for some reason. I can insmod or modprobe it and it loads but no change in alsamixer.

Any ideas?

Thanks,

Kevin

After several attempts and reloading Ubuntu on several occasions, going to float this out there and see if someone smarter than I can point out whatever dumb thing I am doing.

Using Lucid and the ALSA 1.0.23 install script. This is an Asus NVIDIA GT 220 card (no SPDIF). Same issue(s) with NVIDIA Drivers 195 and 256 Beta.

Using this for the Modprobe:

I get this:

Using this modprobe:

I get this instead:

But in doing so the Syslog throws errors like this:

Testing seems to work, but produces no sound. Tried card 0, devices 3, 7, 8, and 9. Same issue with aplay and speaker-test. i.e.
and

Verified the user is in the right group:

This is an Asus M4A785-M motherboard with an onboard ATI 4200. Both it and the audio have been disabled. Maybe just stared at this thing too long to figure out is wrong. Any feedback would be appreciated.
