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.
