Howto | Debug Debian Sound21 Mar 2009
Sound is one of those things in Linux which either works out-of-the-box, or drives you berserk. The following instructions did not solve my problems, but I leave them here for future reference.
The gospel for sound according to Debian:
Step 1: Make sure you have the sound system fully installed
# apt-get install alsa-base alsa-oss alsa-source alsa-utils # apt-get install alsamixergui alsaplayer alsaplayer-common alsaplayer-gtk alsaplayer-jack # apt-get install alsaplayer-oss snd-gtk-alsa vlc-plugin-alsa alsaplayer-jack jack jackd
Step 2: Determine your sound card
# lspci -v | grep -A 6 Audio 00:14.2 Audio device: ATI Technologies Inc SB600 Azalia Subsystem: Micro-Star International Co., Ltd. Unknown device 7297 Flags: bus master, slow devsel, latency 64, IRQ 22 Memory at fe020000 (64-bit, non-prefetchable) [size=16K] Capabilities:  Power Management version 2
Step 3: Run module-assistant
# apt-get install module-assistant # module-assistant
If this fails stating cannot find
# cd /usr/src/linux-headers/linux-headers-2.6.21-2-k7/include/linux # ln -s autoconf.h config.h
The solution to the problem is often as simple as adding a line at the end of
/etc/modprobe.d/alsa-base along the lines of:
$ options snd-hda-intel model=xyz
To determine sound chip model:
# aplay -l **** List of PLAYBACK Hardware Devices **** card 0: SB [HDA ATI SB], device 0: ALC861VD Analog [ALC861VD Analog] Subdevices: 1/1 Subdevice #0: subdevice #0 # cat /proc/asound/cards 0 [SB ]: HDA-Intel - HDA ATI SB HDA ATI SB at 0xfe020000 irq 22
/usr/share/doc/alsa-base/driver/ALSA-Configuration.txt.gz. Open with nano and search for your soundcard chip as shown above.
options snd-hda-intel model=3stack works for many motherboard integrated chips with shared surrounds. Sometimes it is also possible to use the more generic
options snd-hda-intel model=ref, which the hda driver uses to load manufacturer specfic presets (SigmaTel, Realtek, etc.). The full list is available in ALSA-Configuration.txt in the driver tarball under alsa-kernel/Documentation/.
Restart sound system
# cd /etc/init.d # then ./alsasound restart
Play Test Sound
# locate *.wav /usr/share/sounds/KDE_Beep_RingRing.wav /usr/share/sounds/KDE_Beep_ShortBeep.wav # aplay /usr/share/sounds/KDE_Beep_RingRing.wav Playing WAVE '/usr/share/sounds/KDE_Beep_RingRing.wav' : Unsigned 8 bit, Rate 22254 Hz, Mono
