Try with Linux 3.15 (or at least something recent) and ALSA 1.0.28. Reopen the bug if the problem continues and try to provide a bit more emerge information, kernel config, dmesg, lspci, and what else you can think of. Nothing to work with yet here. Change the status to UNCONFIRMED if the problem persists...
