No sound with Debian

Giguli · 08-11-2004, 11:38 AM

I get this error message when I log in KDE:

Code:

Sound server informational message:
Error while initializing the sound driver:
device /dev/dsp can't be opened (No such device)
The sound server will continue, using the null output device.

I have added myself into audio group.

This is what lspci gives:

Code:

0000:00:11.5 Multimedia audio controller: VIA Technologies, Inc. VT8233/A/8235/8237 AC97 Audio Controller (rev 40)
0000:01:00.0 VGA compatible controller: nVidia Corporation NV17 [GeForce4 MX 440] (rev a3)

I have compiled kernel (2.6.7) myself. I don't know what module I should choose. I want use ALSA. My motherboard is: EPoX 8k3a

You want to make sure that you have compiled the module CONFIG_SND_VIA82XX=m and that you have installed the packages alsa-base and alsa-utils then once they are installed use the alsaconf to setup the sound and run the alsamixer as the normal user to set the default levels for both the Master and PCM volumes.

Code:

[HappyTux:/home/stephen]# grep -i via /boot/config-2.6.8-rc4-ck2
# CONFIG_MVIAC3_2 is not set
CONFIG_BLK_DEV_VIA82CXXX=y
CONFIG_VIA_RHINE=m
# CONFIG_VIA_RHINE_MMIO is not set
# CONFIG_VIA_VELOCITY is not set
CONFIG_AGP_VIA=m
# CONFIG_I2C_VIA is not set
CONFIG_I2C_VIAPRO=m
CONFIG_SENSORS_VIA686A=m
CONFIG_SND_VIA82XX=m
CONFIG_SOUND_VIA82CXXX=m
CONFIG_MIDI_VIA82CXXX=y

If you have the proper module compiled and loaded then you should see output like this when you use the command lsmod.

Code:

[HappyTux:/home/stephen]# lsmod

If not then use modprobe snd-via82xx to load it and the required extra modules and make sure that you compile the OSS compatibility module as well (CONFIG_SND_OSSEMUL=y) for apps that need it.

Code:

[HappyTux:/home/stephen]# grep -i oss /boot/config-2.6.8-rc4-ck2
# CONFIG_CHR_DEV_OSST is not set
CONFIG_SND_OSSEMUL=y
CONFIG_SND_MIXER_OSS=m
CONFIG_SND_PCM_OSS=m
CONFIG_SND_SEQUENCER_OSS=y
CONFIG_SOUND_OSS=m
