PulseAudio High CPU Usage. I've noticed that when playing games, PulseAudio uses a less than insignificant amount of CPU time and this doesn't seem to have any real valid reason. It's 0% when idle (as expected) but if a game is playing audio, it can be between 2 and 50%, depending on the game. Running Factorio for example causes Pulse to use 15-20% CPU …

The pulseaudio CPU usage goes down to 7 - 6%, I think it is still a lot, but better than 13%. Changing values of nice-leve and realtime-priority did not changed anything. I can't see any setback of sound quality, should I? Last edited by sifrax (2012-06-26 06:51:44)
