Sometimes I get a data block of random noise... But that might be DMA/interrupt related buffer-underrun, although I do not see any significant messages. Or sox/play has a bug.
Have been playing 4 channel wav with aplay for about an hour and I have not experienced any noise (via line-out + headset), so not sure what could cause it.
In my experiments, playing music is done by sox/play:
play somefile.mp3 remix 1 1 2 2
Let me try this.
now playing some mp3, but I think the sox parameters should be:
play somefile.mp3 remix 1 2 1 2
Ah, yes you are right!
so the stereo input will be stereo on the headset (ch1-2) and on the handsfree (ch3-4)
Now it sounds even better and like real stereo :)
BR and thanks, Nikolaus
