Whiteboard

Note: the people in the audience have not had problems with the audio latency and find it to be working just fine.
On the previous audio gaming session, 16 ms (one 60 Hz frame) was a reasonable target to aim for w r t latency.

[nobody-signed-up-for-this-one] Investigate if there are (open source) apps that are failing at syncing audio/video: TODO

See http://arunraghavan.net/2012/11/pulseconf-2012-report/ for the notes about "low latency" on the PulseAudio miniconference.
