Subject: Included PulseAudio consumes too much CPU when launched with high priority
From: Nable 80 <nable.maininbox@googlemail.com>
To: submit@bugs.x2go.org
Content-Type: text/plain; charset=ISO-8859-1
Package: x2goclient

When I use sound forwarding and launch inside X2Go session some application
with sound support, pulseaudio.exe at client side starts consuming ~100% CPU.
By default, X2Go Client starts pulseaudio.exe with high priority (13).
When I set priority to "Above Normal (10)" PA's CPU load drops to 10-20%.
With "Normal (8)" it drops to almost 0%, although sound is still played stable,
without any additional delays.

I'm using WinXP SP3 (32-bit) on my laptop with single core CPU.
This issue seems to be "PulseAudio 5.0 && WinXP"-specific.
