https://git.kernel.org/cgit/linux/kernel/git/tiwai/sound.git/plain/Documentation/sound/alsa/Channel-Mapping-API.txt

seem chnmap type _FIXED , _VAR and _PAIRED does not fit when LFE and FC can
be swapped for internal speaker and external speaker

https://git.kernel.org/cgit/linux/kernel/git/tiwai/sound.git/commit/sound/pci/hda?id=0fb87bb474f978446786263deff6263284e6e011

How do the driver implement channel map when codec has  swap center/lfe
switch ?

Do chnmap contain both {FL FR RL RR FC LFE} and {FL FR RL RR LFE FC} ?
