I built a test KMP containing the USB audio driver(s) in OBS home:tiwai:bsc1206766-kmp1/usb-audio repo. Fetch usb-audio-kmp-default package from http://download.opensuse.org/repositories/home:/tiwai:/bsc1206766-kmp1/openSUSE_Factory/ and install it. This will replace the driver on the latest TW kernel (as of now 6.1.1-1). If this fixes the problem, it means that the problem is somewhere in the USB audio driver update between 6.0.x and 6.1.x). If the problem persists, it means the problem being in a deeper level.
