OK, it's good to know that the old code is working fine. I'm building a test kernel with the latest upstream fixes wrt usb-audio, with a little hope that it fixes as well. The package is being built in OBS home:tiwai:bsc1182552 repo, will be available later at: http://download.opensuse.org/repositories/home:/tiwai:/bsc1182552/standard/ Please give it a try later. Note that this is a package with unofficial key, so Secure Boot won't work with this kernel. Disable Secure Boot on BIOS if you enabled it on your machine.
