Description

Hello,

I use Ubuntu precise 12.04 64 bits. This distribution uses the pulseaudio sound system.
In Dolphin, I'm not using pulseaudio but alsa or openhal plugin, because they emulate sound faster than pulseaudio and are less cpu consumers. Is it a bug? I think, normally, in a wonderful computer world ^^, a dsp plugin should have better performance with the sound system it is made for.

Config:
Ubuntu precise 64 bits
AMD Radeon 7850
Catalyst 12.6
Dolphin 3.0-750, compiled from git 11 august 2012.

I could reproduce this problem withh all games I play.
I attach some Dolphin log relative to audio.

Thanks for your help.
