TLV320AIC3101 Audio Capture Broken Pipe

Refer this post - http://e2e.ti.com/support/dsp/davinci_digital_media_processors/f/716/t/254728.aspx

Ok, I understand this tuning for TVP5158.
But what can we do for TLV320AIC3101 to avoid "Broken Pipe" while capture ?

Thanks for Your advice. Changes are done, I will test audio recording for some days.

Best regards Holger

After testing for a longer time I can say that the behavior became better with changes for AIC configuration in linux psp.
But I also made some modification.
We do not recording in ulaw format, we write pcm files now.
Converting of pcm to wav is done offline independent from recording.
And I also added a recovery if "Broken Pipe occurs".
Now audio capture / record is running well.
Best regards Holger

Good to know that things have improved. Please share any of your findings / fixes for the benefit of others.

The main change is to try recover from capture "Broken pipe":

Sometime this problem occurs, than we try to recover.

The recover was successful for us currently.

                /* Read interleaved frames */
                err = snd_pcm_readi (capture_handle, temporary_buffer, len);

                if ( err != len )
                 {
                     LOG(LOG_ERR, "%s: Read from audio interface failed (%s)", __FUNCTION__, snd_strerror (err));
                     len = 0;
                     captureStats.errorCnt++;
                     captureStats.lastError = err;
                 }

                /* Try to recover from "Broken Pipe" error */
                if( err == -EPIPE )
                {
                    LOG(LOG_ERR, "%s: %s, Capture Audio failed, try to recover!", __FUNCTION__, snd_strerror(captureStats.lastError));
                    err = snd_pcm_prepare(capture_handle);
                    if (err < 0)
                    {
                        LOG(LOG_ERR, "%s: Can't recovery, snd_pcm_prepare failed: %s", __FUNCTION__, snd_strerror(err));
