Recently the trunk build of Mythtv checks if pulseaudio is running and aborts if it does. This is because of the rather large audio delay it induces and the resulting sync with video issue. Here is the reference http://svn.mythtv.org/trac/ticket/5473 particularly: Changed 3 months ago by sPOiDar ? FYI, I get ~300ms lag on 0.22 with audiooutpulse-0.12.2 when using pulse. Changed 13 days ago by danielk ? (In [20310]) Refs #5473. Adds a check for PulseAudio? at startup of mythfrontend and mythtv. PulseAudio? causes delays that range randomly between 500-2000 ms when playing back audio, so we abort startup if the pulse audio server is currently running. Note: I've referenced a ticket that adds PulseAudio? support to MythTV, but even using the PulseAudio? API's the delay is still 300 ms; if we can get that down in the 20 to 50 ms range we can adjust when we display the video frames to compensate for the delay (which we should be doing anyway when using multiframe deinterlacers). --- I haven't contributed to that thread, but observed the same random delay and just realized it was pulse related when myth made me turn off pulse. Any thoughts on this?
