[CLAM] the object rightChannel is not ready

[Xavi Rubio]

Are you sure that is rightchannel the processing that crashes? I see
that the only processing you don't configure is mAudioIn, and the code
related to audioout seems correct (if the other audiooout starts correctly
I assume that you have the right options for audio devices).

Anyway, try to see if you have any difference with this section of code
in Playback example, because it should work without problems.
