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:1293:(snd_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 |
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. Quote:

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. Quote:

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). Quote:

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.

My pc has always been in reach of the TV and i have always used it as a speaker just wanted a one cable setup now.
