hda-intel Intel Corporation 82801G (ICH7 Family) High Definition Audi

Hi,
I have some problems in Arch (audio). I downloaded alsa-utils and oss packages via packman and after alsaconf configuration (it told me Have fun. Does it means fun with settings? ;-) ) I cant hear anything.

I tried aplay to play audio:

ALSA lib pcm_dmix.c:864:(snd_pcm_dmix_open) unable to open slave
aplay: main:545: audio open error: Device or resource busy

And this is VLC utput :

ALSA lib pcm_dmix.c:864:(snd_pcm_dmix_open) unable to open slave
[00000332] oss audio output error: cannot open audio device (/dev/dsp)
ALSA lib pcm_dmix.c:864:(snd_pcm_dmix_open) unable to open slave
[00000332] main audio output error: couldn't find a filter for the conversion
[00000332] main audio output error: couldn't create audio output pipeline

aplay and VLC runned with root privilegies....

Please help

Make sure you have compiled in the kernel the driver for your card. Then use alsamixer to change mixer settings, unmute it.

Are you in audio group?

i tried as a root. Still not running. Is there any way (i mean another way).

I switched from Debian due to low support of my hw (using Lenovo N100 core2duo), in ARCH everything running as i want. But only the audio cannot be heard ;-( //Iam playing my music on mobile(cell) phone ;-)

If there is not a way, I will still use the ARCH because my wifi (intel ipw3945) works fine.

Thanks in advance!

I have the same card. works fine with stock kernel and with custom kernel.

In the custom kernel I disabled oss. (I don't have any use for it) so I don't have /dev/dsp. I use alsa only but this does not need dsp device.

You probably have some other application that has opened /dev/dsp (the OSS device).

When an app uses /dev/dsp the ALSA software mixing can't work. See if you have artsd or esd started and disable them.
