Thanks. We can have total channel number.
Then do we have common DT settings/method to indicate below ?
I guess we need this settings on both CPU/Codec.

6ch
 - 2ch x 3
 - 6ch x 1
 - ...

12ch
 - 4ch x 3
 - 12ch x 1
 - 8ch x 1 + 4ch x 1
 - ...

Moreover, my IP can output 6ch x 1 sound via 8ch wide
(= with empty 2ch).
I guess I need this settings on both CPU/Codec too.
Do we have common settings/method ?
