Sound lag problems with pulseaudio
Last modified: 2009-04-23 18:17:51 EDT
Description of problem: In Fedora 10 I experience sound lag problems in flash player when playing flash games or watching movies.
Version-Release number of selected component (if applicable):
How reproducible: Play a flash movie on youtube or play a flash game somewhere on the internet.
Steps to Reproduce:
1.Install Fedora 10
3.Play a flash movie or game.
The sound is lagging in the movie or game.
No sound lag.
I was able to solve this in fedora 8/0 by creating a ~./asoundrc file with the following contents:
However, now in fedora 10 this doesn't work anyomore.
Do you see the lag right away? I mean, from the very beginning is it like .2 seconds off or does it start off synchronized and slowly drift?
For me I see it slowly drift out of synch, this is mostly observed with xine/miro.
When I open for instance http://onslaught.playr.co.uk/ in firefox and wait for the game to begin then the sounds of the first rockets being fired by the turret are still in sync but right after that is starts falling behind. The lag is however constant just a little behind the animations.
This is the same with every game. Like the gambling (fruitmachines) on http://www.slotplaza.com/
Playing video on for example youtube changes from video to video. The lag is almost never constant. Sometimes it is in sync, sometimes it is not.

This is brokeness in Flash. PA provides correct timing information to applications via snd_pcm_delay() and similar calls.
Please open a bug against Flash.
Closing now, feel free to reopen, if you manage to reproduce this issue with open source software!
