ALSA: hda - Disable sticky PCM stream assignment for AD codecs
The sticky PCM stream assignment introduced in 2.6.36 kernel seems causing problems on AD codecs. At some time later, the streaming no longer works by unknown reason. A simple workaround is to disable sticky-assignment for these codecs. Tested-by: Vasily Khoruzhick <anarsoul@gmail.com> Cc: <stable@kernel.org> Signed-off-by: Takashi Iwai <tiwai@suse.de>
