I have the same setup, and ALSA gives me those loud clicks as well (3 of them).
A running console reports that the system is actually modprobing for 3 more
snd-cards. It reports this every time a sound is played, something like:
modprobe snd-card0 :
modprobe snd-card1 : No such device
modprobe snd-card2 : No such device
modprobe snd-card3 : No such device
No idea why. I have the sound configured explicitely for the one card in
modules.conf, and I have never know ALSA to probe the modules like this before.
This is using the stock Suse 7.3 with the ALSA install that comes by default
(5.12a I believe).
