Subject: audio: Lower default wakeup rate to 100 times / second
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=40a814b0b1789b94c483190b3208729b5182e5bd;p=qemu.git

audio: Lower default wakeup rate to 100 times / second

This is more then plenty to keep audio card fifos filles / emptied.

This drops host cpu-load for audio playback inside a linux vm from
13% to 9%.
