Hello, After upgrading to release 0.9.14, I'm getting these message in /var/log/messages. Is this useful to anyone? linux pulseaudio[25073]: module-alsa-source.c: ALSA woke us up to read new data from the device, but there was actually nothing to read! Most likely this is an ALSA driver bug. Please report this issue to the PulseAudio developers. I've provided "stat" and "list" from pactl below. Anything else desired?
