How I should do that ?, where is this snd-usb-audio is loaded
I have in my  modules.conf:
alias net-pf-4 ipx
alias autofs autofs4
alias eth0 eepro100
above snd-ens1371 snd-pcm-oss
probeall usb-interface usb-uhci

Apparently I have it since I have snd-pcm-oss in module.conf, Is that 
correct ?

I am not sure I am following ,so  the problem could come from a mixed 
OSS/ALSA driver,
the OSS would come from the webcam's Mic. Is that correct ?

1) It does not look (from modules.conf) that I am using any OSS driver 
for the mic's web
2) Let assume  it is the case, how the OSS driver is loaded ? can I 
prevent it being loaded ( I don't need the webcam
s mic after all !)
3) Apparently , I have the OSS-emulation of ALSA (snd-pcm-oss) , could 
it be any other reasons ?
4) Is there any "snd-usb-audio" like for ALSA I can use ?

Thanks

Chris
