Nvidia HDMI Audio Not working after multiple attempts

[bobDole]

I have tried to get audio via HDMI to work with my GTX 570 without success. I have searched and tried quite a few approaches which I'll outline below.

First, HDMI audio does work with my setup. I dual boot with Windows 7 and it works perfectly fine there.

The motherboard is an Asus P8Z68 Deluxe/gen3 (it has onboard audio). The video card is NVidia GTX 570. I'm running Fedora 16.

Output from aplay -l with a vanilla /etc/modprobe.d/sound.conf:

Most of the guides out there have you test each one until you hear audio. Running aplay -D plughw:1,7 somefile.wav plays and confirms that the device is working! The guides then generally have you modify /etc/modprobe.d/sound.conf with a probe_mask. Others will have you modify /etc/pulse/default.pa Whenever I modify /etc/pulse/default.pa, pulse audio doesn't load. So I reset that file to the default. I've had success with sound.conf

I managed to change my aplay -l output to this with the following sound.conf:

# aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: NVidia [HDA NVidia], device 3: HDMI 0 [HDMI 0]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

# cat /etc/modprobe.d/sound.conf
options snd-hda-intel probe_mask=-1,0x02 index=1,0 enable=0,1

Doing aplay -D plughw:0,3 somefile.wav works with this. I would expect with only one active card and one active device that pulse audio or alsa would have no choice but to choose it. Yet, applications such as mplayer and vlc do not emit any sound.

A handful of guides suggest setting up a .asoundrc file as follows:

$ cat ~/.asoundrc
pcm.!default {
    type hw
    card 0
    device 3
}

This has no effect. I've tried it with/without sound.conf and adjusting card 0 to card 1 and device 3 to device 7 and still no effect.

This is where I'm stuck. Any help would be appreciated!

edit: I did make sure the outputs were unmuted when testing with vlc or mplayer or aplay -D. I checked and unmuted the outputs with alsamixer

Ahh yes, those two links. I've read those a fair number of times haha. As I mentioned before, anytime I add to default.pa, pulse audio doesn't start. So, the first problem I encounter with that link is adding 'load-module module-alsa-sink device=hw:1,3' to the default.pa. The next problem is when it says and then if you want output to BOTH HDMI and Analog add...well, I don't want both, I only want hdmi audio. Even so, following those instructions fully results in no sound.

One thing I notice is that with a vanilla default.pa, vlc doesn't give any error messages and alsamixer seems to work fine. If I change default.pa, then vlc complains about not being able to connect to pulse audio and then not being able to open /dev/dsp. Alsamixer complains about not being able to connect to pulse audio IIRC. With or wihtout a vanilla default.pa, aplay -D plughw:1,3 somefile.wav still works.

Last thought of the night: I've tried adding the load-module lines and set-default-sink lines at the middle of the file, at the end of default.pa, and separted as recommended in the first link. None of that makes a difference.

In case anyone else is having difficulties. This is what worked for me.

*** if you have aplay working, your problem may have been the same as mine (step 6)****


Fedora 16 64 bit
Kernel: 3.2.6-3.fc16.x86_64
Graphics card: GT 430

1. Assuming "aplay -D plughw:...." is working
2.. Download pavucontrol
3. Add the line "load-module module-alsa-sink device=plughw:x,x" to /etc/pulse/default.pa in its designated place
4. type 'killall pulseaudio' in the command line
5. type 'pavucontrol' in the command line
6. Go to the tab 'configuration' and make sure that all profiles are 'off'
7. Under the tab 'Output' you should see your audio controller, make sure that volume is set to 100 and that it is unmuted.
8. Fire up rhythmbox and try it out.

I hope this helps

Perfect. Thanks for that. This worked for me.

I also wanted to get combined output to the analog ports (headphones etc.), so I added the following lines in addition to the above:

load-module module-combine
set-default-sink combined

So my /etc/pulse/default.pa now looks:

## Psyk
load-module module-alsa-sink device=plughw:1,7
load-module module-combine
set-default-sink combined
## End
