Hello,
I have an onboard Intel 810-based audio card in my box. It used to
work nicely with a 2.4-series kernel and some earlier (can't remember
the exact version) ALSA drivers. Recently, I've done a serious update
to Debian testing (from stable) and kernel 2.6.0. I've compiled the
kernel with ALSA support including the formerly working i8x0 driver.
(Tried both statically compiled and as modules.) Everything works
flawlessly, at boot time it tells me the driver is started (or when
using modules, everything is loaded nicely),
I can set the sound levels (so they are NOT muted :)) using aumix or
alsamixer, /proc/asound entries seem correct, I can play audio files
with ALSA-based as well as with OSS-based players (various XMMS
output plugins, mpg123, alsaplayer, even tried cat /bin/sh > /dev/dsp),
but still, no sound comes from the card.
Everything's all right with the hardware setup, it works nicely under
Win. Any ideas what shall I do?
Now, the logs & stuff...
The relevant kernelconfig entries are:
#

CONFIG_SOUND=y

CONFIG_SND_SEQUENCER=m
# CONFIG_SND_SEQ_DUMMY is not set
