Hi alsa-devel list,
I'm currently working on an internal project.
Here is some details :
This embedded project includes a AT91SAM9260 CPU and a WM8900 codec.
Audio driver is using ASoC API.
Audio data could be either switch from I2S or DSP A, but I prefer the second
Audio Codec is master.
We have an issue : when we play a right channel stereo track, sound is
played on right channel, but sometimes on left.
This issue could happen right after starting kernel, or later after 10-20
With Frank Mandarino, we've checked any issue from SSC(audio bus) or PDC
(dma) controlers, but no much success.
Any idea to help us debugging this issue would be welcome !
