I now saw you also filed a log in bug 1284415. The following message: alsa-sink.c: Underrun! alsa-sink.c: Scheduling delay of 21.88ms > 14.11ms, you might want to investigate this to improve latency... Indicates two things: 1) A playback stream is active. Executing "pactl list sink-inputs" should help you understand which stream. 2) Ogra posted something about not being able to get RT priority. The above shows that this is a practical problem for us - it causes audio drop outs. You might not notice it much with normal music playback, but it would be worse for, say, VoIP. -- David Henningsson, Canonical Ltd. https://launchpad.net/~diwic -- Mailing list: https://launchpad.net/~ubuntu-phone Post to : ubuntu-phone@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-phone More help : https://help.launchpad.net/ListHelp
