HDMI Sound


I am having trouble getting sound to work through hdmi, I changed the device in the kde settings for multimedia and it now works in Amarok but Mplayer and VLC are refusing.

This is the error i am getting with mplayer

[AO OSS] audio_setup: Can't open audio device /dev/dsp: No such file or directory
[AO_ALSA] alsa-lib: pcm_hw.c:1293snd_pcm_hw_open) open '/dev/snd/pcmC0D0p' failed (-2): No such file or directory


I have disabled my sound card in the bios to save confusion (on my part)
Upgraded my kernel to 2.6.37

My gfx card is a NV gt 430 xt

See http://www.linuxquestions.org/questi...-linux-819172/ & post back with your comments.

I have the very same card. My solution was to upgrade kernel to 2.6.37 because 2.6.33.4 does not support fermi codecs.

EDIT: I initially misread your post and just saw that you already upgraded to 2.6.37....

1. Generate a nvidia-log report (see http://www.nvnews.net/vbulletin/showthread.php?t=46678)

2. According to the content of this report, try one of these (adjust the hw argument to your hdmi device address)

1) Make sure you're running X using the NVIDIA driver and it's driving your HDMI monitor.

2) Run alsamixer -c 2 and unmute everything.

3) Run the following; one of them should work:

speaker-test -c 2 -r 48000 -D hw:X,X

What is the output of these commands:

Code:
aplay -l

cat /proc/asound/devices

cat /proc/aspound/cards

lspci -vv

I have seen the thread you linked to which is what prompted me to upgrade my kernel. I just had a quick go at creating a sound.conf but that removed what function i did have.

I am a little short on time at the moment but the output of the commands you listed are below, and i will try and do a nv log tonight.

I don't think there is any problems with the hardware as i am able to play sound in Amarok and VLC now i have selected the card and subdevice instead of the default so i believe i just need to figure out where to make it the system default.

Just thought speaker-test -c2 -twav -Dplughw:0,9 also give audio.

I dont seem to be getting anywhere with this at all

Edit

Just thought i should make clear that every thing works and for kde apps its fine but outside of that mplayer etc they are looking i assume for the old analog card.

I was just going over what i had done i knew it would be something silly and as usal it was.

I created a ~/.asound.rc with all the correct details but after going over every thing i spotted that it should be ~/.asoundrc after moving that file everything works.

Edit just adding the contents of that file for anyone else who may need it (or myself at a later date).

After working with this problem for awhile I decided it wasn't worth the effort, unless, of course, as someone pointed on in the thread below, you are plugging your computer system into your home entertainment center.
