Hi

Using hotplug (and hence not udev) with a 2.6.14.3 custom compiled kernel
with modular alsa support. Modules loaded :

snd_seq_dummy           3844  0
snd_seq_oss            36224  0

An attempt to restart the sound server quits complaining about no /dev/dsp
being present (present, mind you, not permissions). However I see :

# ls -ltr /dev/dsp*
crw-rw----  1 root audio 14,  3 2005-12-05 22:51 /dev/dsp0
crw-rw----  1 root audio 14, 51 2005-12-08 00:39 /dev/dsp3

crw-rw----  1 root audio 14,  3 2005-12-08 00:39 /dev/dsp

lspci indicates that a multimedia card is present (just in case someone is
wondering, this laptop's sound has worked in the past with older kernels,
before I sent it to the vendor for servicing) :

An attempt to start alsamixer as root quits with :

alsamixer: function snd_ctl_open failed for default: No such device

dmesg reveals no information about any audio devices. In /var/log/syslog, I
find a few intriguing lines :

An attempt to restart alsa-utils fails :

lspci says that a sound card is present, and yet this cannot find it.

My modules.conf contains the following sound related lines (among a lot of
others) :

Just tried a Knoppix live CD. Sound works with i810_audio. So, there is no
hardware problem here. Can someone help me debug this problem in Debian ?

Thanks.

Well, you have the entry in /dev. However, that just points to the
actual "device", the code which handles sound.

My modules are about the same, except, of course, for the module
for my sound card (an old 810)

snd_intel8x0           29532  0
snd_ac97_codec         92896  1 snd_intel8x0
snd_ac97_bus            1760  1 snd_ac97_codec

So, where is the module with the code to access your soundcard
and provide the device driver?

I think I had the wrong module ! Sorry about the whole mess. Sound is up and
working.

What happens if you manually tro to load the module:

modprobe snd-intel8x0

Will the module get loaded? Do you get some error message? Do you see some
useful information from dmesg?

If sound works after manually loading the module your hotplug is
configured wrong in some way. Maybe the module is listed in blacklist?

Do lsmod while Knoppix is running, and compare that with the lsmod
output under Debian.  Why are you using hotplug instead of udev?
