Problem 2: Test tone is being presented by the user application, providing a 1Khz tone sampled at 44.1Khz. The data are S16_LE, right channel only. Left channel is quiet. The data seems to slip back and forth from left to right channel. This is reproducable and verified with a scope trace.
Anybody have any ideas what might be going wrong here? Traces for codec reg dump and mcbsp are attached.
As Jarkko already asked: are you seeing the channel switch while running or is it happens on playback start?
AFAIK this phenomena can be also seen on Beagle board.
I have done some investigation regarding to these, but so far I can not say that I know what causes it.
BTW: these are separate issues (startup switch and runtime switch).
Thanks, twebb
