I am working with digital TV in Linux platform. Currently I am facing with one issue in audio. When I give stereo audio to
snd_pcm_write_i
Function and after long time running the audio channels get swapped. That is, right channel audio hearing in Left channel and Left in Right. I dumped the PCM data in to a file before giving to alsa in issue case and played using 'aplay' and audio is good.So I think the PCM data is OK. In my system,'AK4643' audio codec device is used. Does any one faces this issue? If so please help me.
The issue was associated with the I2S driver . Fixed the issue with updated driver from chip vendor.
