alsa name mismatch处理办法
2.6.11以来snd_intel8x0的alsa一直有问题:codec_semaphore: semaphore is not ready
codec_semaphore: semaphore is not ready
set_control:894: warning: name mismatch (Center Playback Switch/Master Mono Playback Volume) for control #2
set_control:896: warning: index mismatch (0/0) for control #2
set_control:898: failed to obtain info for control #2 (No child processes)
好像一直没出补丁，今天偶然搜到处理方法极简单:
先alsactl store即可。
不过启动时还有codec_semaphore: semaphore is not ready
