Hi Margarita,

Thanks for your reply..,

rc = snd_pcm_writei(playback_handle, pInBuf, size/2);
if (rc == -EPIPE)
{
/* EPIPE means overrun */
OSA_ERROR("audio play underrun occurred\n");
snd_pcm_prepare(playback_handle);
return 0;
}
else
{
if (rc < 0)
{
OSA_ERROR("audio error from write : %s\n", snd_strerror(rc));
}
else if(rc != NUMSAMPLES )
{
OSA_ERROR("audio short write:%d frames\n", rc);
}

return rc;
}

I'm getting the ERROR logs... Before It was under run occured

ERROR (audio_playback.c|Audio_playbackPlay|267): audio short write
ERROR (audio_playback.c|Audio_playbackPlay|267): audio short write
ERROR (audio_playback.c|Audio_playbackPlay|267): audio short write

Hi,

In file ipnc_mcfw/demos/mcfw_api_demos/multich_usecase/playback_tsk.c

if(frameFetchTime < instance->interFrameInterval) {
OSA_waitMsecs(instance->interFrameInterval - frameFetchTime);
}
else {
PB_ERR("Spent %d msec in getting free IPC Bits Out Buf\n", (getEmptyEnd - curTime));
}
Sometimes I'm getting PB_ERR logs .., the value goes upto 100 msec !!!!

In by default, instance->interFrameInterval = 25, frameFetchTime = 5 or 6(based on packet time )

Whether problem with sending audio date to snd_pcm_writei() ???

Suggest me to solve this issue ??
