We need more info. Please post the output of

Code:
cat /proc/asound/cards
and

Code:
cat /proc/asound/devices
as well as

Code:
uname -a
Do you have a Fermi GPU?

Did you install the nvidia driver?

Are you running 32 or 64bit distro?

Can you please supply an nvidia-bug-report (see http://www.nvnews.net/vbulletin/showthread.php?t=46678)

Your first step is to make sure the alsa subsystem detects your HDMI subdevices then you can configure the system to output sound.

Nvidia bugreport
ALSA report

Couldn't figure whether my card is of Fermi generation. I'd go with it's not:P
Yes, Nvidia driver:
Code:
NVRM version: NVIDIA UNIX x86 Kernel Module  260.19.06  Mon Sep 13 06:35:06 PDT 2010
GCC version:  gcc version 4.4.5 (Ubuntu/Linaro 4.4.4-14ubuntu5)
32 bit system

Yes, guess i have enough info for configuration, but detecting hdmi device seems rather impossible.
Edit: tried also Ubuntu 11.04 alpha, no luck there either.
Thanks for support!

Bump.

lpallard 01-27-2011 04:44 PM
Sorry I got busy and did not have a chance to post back...

I believe your card is not fermi architecture. It has the G84GL GPU and its basically the GF 8 series (G84). I dont see why a new kernel would not understand the G84 architecture. For myself, I have the new fermi architecture and the kernels prior to 2.6.35 would not handshake with the fermi hardware codecs so thats why sound did not work. Reading over the web for the Quadro cards prior to the new fermi architectures, people are recommending downgrading the driver to something like 180.XX or 190.XX... Have you tried that?

I think the kernel see the HDA nvidia controller's codecs fine...

I'd try downgrading to a previous release of the driver and post back.

layr 01-27-2011 04:58 PM
Whoa, i've read loads of threads, everyone recommended upgrading drivers. Will try downgraded drivers (Y)

lpallard 01-27-2011 05:10 PM
Upgrading or downgrading? You already almost have the latest revision (260.19.06?) The latest is 260.19.36

If I were you I would try the older version first and if it doesnt work, try the latest. If it still doesnt work, we know it is not the driver.

The audio counterpart of the hdmi in linux is really flaky.... My other ATI HD5570 card did not work very well either and my new GT430 card barely works..

layr 01-28-2011 10:41 AM
No luck, ver 173 didn't make it. 'aplay -l' still doesn't recognise HDMI device.

Nope, that ain't the case, since everything works OTB in WinXP.

lpallard 01-28-2011 04:28 PM
have you tried the latest driver? if so and it did not work, it sounds like a kernel issue...upgrade to 2.6.36 or .37 and post back.

Moromendas01's reason for posting was not to participate, share information, or to help anyone. It was attach his spam sig. To disguise his intention, he generated the body of his post by plagiarizing one from earlier in the thread. To disguise the plagiarism, he changed a couple of words in what he plagiarized.

Moromendas01 has never posted anything that he wrote himself. Every single one of his posts were generated by plagiarizing someone else. Why? To spam.

Seems to be the case. I searched for ALL posts from moromendas01 from the search tool and every single result I've found were copy-paste of an earlier post, sometimes even completely off-topic with synonyms to slightly change the form of the sentence. I think its a spam robot. What about a ban?

Done.

BTW, did you find sources for his posts in the "Tough Book" and "Debian Squeeze" threads? Those are about the only two for which I wasn't able to prove anything.

Good!

It switched the touchpad to absolute position mode, (Horribly unusable, jumpy mouse pointer, not recommended) but the touchscreen gave no response or output that I could find. Incidentally, I have found no evidence that it works with the CF-18 either, and I believe it produces the same result as it does on the CF-29. See the kernel bug report mentioned above.

Pretty clear to me thats plagiarizing... If its not a spam robot or some kind of PITA spam server its somebody that needs a life...

I got it working using what dimm0k said.

One thing that may help is to make sure the media player outputs to the right device.

For example:
Code:
bash-4.1$ cat /proc/asound/pcm
00-00: ALC269VB Analog : ALC269VB Analog : playback 1 : capture 1
01-03: HDMI 0 : HDMI 0 : playback 1
Then I run:

Code:
mplayer -ao alsa:device=hw=1.3 movie.avi
to have the audio go to HDMI.

Thanks again for the rest, otherwise it wouldn't work. I also had to make hda-intel a module in the kernel.

One HDMI falls-back to analog, the other doesn't; none produce audio in TV

Running the test for the HDA NVidia yields no sound whatsoever. I feel like I am missing something... any suggestions?
I have a fallback to analog (internal) sound issue whenever I select one of my HDMI devices but there is no fallback to the analog ALC272 device whenever I choose the other, nor is there any audio coming from the TV to which I am connected via HDMI. My "aplay -l" is:
Code:
**** List of PLAYBACK Hardware Devices ****
card 0: Intel [HDA Intel], device 0: ALC272 Analog [ALC272 Analog]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 0: Intel [HDA Intel], device 3: HDMI 0 [HDMI 0]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 0: Intel [HDA Intel], device 7: HDMI 1 [HDMI 1]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
