[ALSA] hda-codec - Fix handling of multiple capture streams
Fixed the bug that multiple capture streams conflict on Realtek codec routines. Also, this adds a framework to enable the alternative playback stream, e.g. for VoIP. It's not fully implemented yet, though. Signed-off-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Jaroslav Kysela <perex@perex.cz>
