Here's a simple test: Actually the problem is due to "mismatched" recording and playback rates. My test was recording at 8kHz and playing back at 48kHz. The codec driver only supports playback rate = capture rate. When the playback starts the codec starts clocking at 48kHz which causes the xruns. Will see if the codec driver (tlv320aic3x) can be fixed up. randolph _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
