well, did last a while. I'm not that familiar with kernel

building. But a friend was helpful, so I have now
Linux Grandevitesse 2.6.12-rc1-ce #1 SMP Sat Apr 2 22:59:58

CEST 2005 i686 Intel(R) Pentium(R) 4 Mobile CPU 1.60GHz

GenuineIntel GNU/Linux
installed. Unfortunately, it doesn't change anything

concerning the usb_audio behaviour. I get notches every 3 to

7 seconds again caused by xruns.
Except, OTOH, I did something wrong when patching (sorry for

my ignorance). Can I somehow check if the patch has been

applied successfully by probing the current running kernel? A

location in /proc probably?
 Thanks a lot & best regards
