hi, i've just reinstalled mandrake 9.0 and successfully got usb-audio running, but the sound quality is heavily distorted - to say the least - well basically its all feedback!! it can't be a usb mouse conflict, as was suggested on another list, as i am not running any other usb devices concurrently with my usb m-audio quattro - i only have one usb port on my thinkpad 600E. but i wonder if there is some kind of conflict going on nonetheless. does anyone have any idea what may be causing this? it seems very strange as everything worked fine with tarball alsa 0.9.rc5 and mandrake 8.2 - i'm now using the supplied rpm versions of alsa with mandrake 9.0 - i prefer to use the alsa-project.org tarballs, but in this case i have decided to stick with the supplied rpms to avoid conflicts between the two as happened to me earlier. thanks in advance m~
