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 ?
