Motherboard: A-Bit AWD9-MAX Using 2.6.24, everything is fine, using 2.6.25, no audio (used make oldconfig).. Kernel configs used attached. I did not see any errors of any kind it just did not play any audio, I booted back to 2.6.24, everything working fine again. The second one I enabled debugging.
