[ALSA] hda-codec - add support for swapping center/LFE channels to STAC codecs
Center/LFE channels are located on same jack, so it can be usefull to swap them. Signed-off-by: Maxim Levitsky <maximlevitsky@gmail.com> Signed-off-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Jaroslav Kysela <perex@suse.cz>
