Hi,
thanks for your replies. I have my modules.conf already configured similar to
Miguel's description. Sorry for not including it right away. From Georgi's
very complete system information I found out some new spots in proc to look
for things and I found out that oss emulation devices are there for both
cards on my setup. Only the device names are not created.
I modified Georgi's mknod commands like this:
echo Creating missing Sound devices
mknod /dev/sound/dsp1 c 14 19
mknod /dev/sound/mixer1 c 14 16
chown root.audio /dev/sound/dsp1
chown root.audio /dev/sound/mixer1
chmod 664 /dev/sound/dsp1 /dev/sound/mixer1
ln -s /dev/sound/dsp1 /dev/dsp1
ln -s /dev/sound/mixer1 /dev/mixer1
echo "Sound should be ok now!"
and put them in my rc.local script. That does the job as a workaround. I'll
also try the patch later. Hopefully it works with my 2.4.20 kernel. Jaroslav,
do you know if the patch got rejected completely or only delayed? Any
information from the kernel masters about the subject?
Thanks again to all of you for your help. Finally both soundcards are usable,
cool!
CU,
Richard
