I grepped all files in /etc/hotplug, but I didn't find anything. I simply wanted to replace the matching entry by snd-usb-audio. OK, I'll now reboot and see what happens. I simply added the snd-usb-audio to the bootscripts. > > Is it save to deactivate all OSS support in general in > > the kernel config, or will this cause the ALSA OSS > > emulation to be not working? > > There are separate menus for the OSS drivers and for ALSA's > OSS emulation. ?And just to confuse you, the OSS USB > drivers are located in the USB menu. Argh :) . Thanks a lot for the hint. I guess I'm going to disable all OSS stuff and rebuilding the kernel. Thanks a lot for your help! Gru? & regards ce
