Sound card is a PNP AWE64.
The fix appears to be to change the line in modules.conf to read
post-install sb ...
I have the same problem except in my case (Compaq Armada 7800 laptop) the result
is feedback between the mike and speakers. My sound card is an ESS ES1879 which
also uses the sb driver
The real problem is in rc.sysinit at lines 442-444. It is looking up the alias
for sound-slot-0 and then loading the module by calling modprobe with the alias
name (sb in both our cases). Unfortunately, as email@example.com noted,
the post-install and pre-remove lines in /etc/modules.conf that cause
aumix-minimal to be called are for sound-slot-0 and don't get called for a
modprobe of sb.
I believe the correct fix is to change line 444 of rc.sysinit to modprobe
sound-slot-0 instead of the alias name. This will work for any sound driver,
not just the sb driver. I've made this change and it works great for me.
Incidentally the same thing is done for the sound alias in lines 437-441. I
suspect this should also
modprobe the sound name instead of the alias but don't think it causes any

Will be fixed in 6.51-1, thanks!
