If you connect multiple front ends to one back end this should work (with DAPM routes and so on). If it doesn't work then that's something that should work.
I considered about DPCM, but *maybe* this is not goot match for us. If my understanding is correct, and if I used DPCM for this, all of sound A/B/C are start/stop:ed in same time ?
ex) start sound => start A/B/C and codec stop sound => stop A/B/C and codec
I guess it works if it has this connection
data -> [A] -> [B] -> [C] -> codec
We would like to do is like this
+-+dataA -> [A] -> |M| dataB -> [B] -> |I| -> codec dataC -> [C] -> |X| +-+
init => working: start sound A => working: codec + A start sound B => working: codec + A/B (mixed) stop sound A => working: codec + B start sound C => working: codec + B/C (mixed) stop sound B => working: codec + C stop sound C => working:
I guess current DPCM doesn't support this ?
What you're describing is what I'd expect to happen - I'd say if that's not working it's a bug and we should fix it.
