Subjectalc262 streams synchronization
From
Date

Hello,

I have faced the following issue with alc262 codec on kernel 3.2.34 :

Trying to play a file through vlc (libvlc/emotion), I did not have any sound on the speakers. Having a look at my kernel logs, I have noticed 2 calls to snd_hda_codec_setup_stream() separated by a call to __snd_hda_codec_cleanup_stream().

Nevertheless, adding some debug prints, I have noticed only one call to snd_hda_codec_write() in snd_hda_codec_setup_stream() to set the stream id. It seems like the stream id of the codec was not synchronized with the flag p->active the kernel maintains for the codec.

Setting the no_sticky_stream field in patch_alc262.c solved the issue. What about setting that field ? Am I the only one who faced that issue ?
