Hi,

yes, I also have that. There is something else I found out. When the modules 
are first loaded at system boot, there is a rather loud popping noise. I now 
changed my system bootup process to automatically unload and load the alsa 
modules with some delay inbetween. When they get loaded the second time after 
unloading it pops once more. If you reload them after that, that popping 
sound won't come again. So once the card is in a usable state, the pops are 
gone also. I have to correct one thing, too. Reloading the alsa drivers once 
solves the problem always now. I only have trouble reloading them if sound 
was in use before. Then sometimes some modules are marked in use even though 
I killed all apps that used them. Probably those were the cases where 
reloading didn't work as a workaround.

One other thing, there are two channels named IEC 958 in my alsa mixer. When I 
unmute the second one the card starts to generate a high frequency beep that 
can only be stopped by rebooting. No idea what that is ;)

Is Mandrake using devfs?
