Package: pulseaudio
Version: 2.0-6
Severity: normal

Dear Maintainers,

I installed Wheezy KDE amd64 on several machines:

*Sempron 3000+ on GA-M55S-S3 (motherboard output)
*Athlon X2 4850e on MSI K9VGM-V with HD4670 (HDMI output from the graphics
card)
*Turion X2 TL56 (integrated speakers)
*Core I3 2120 on ASUS P8H67 (motherboard output)

and on startup I'm getting a strange audio delay/crackling.

The worst sound delay is on the Sempron, the crackling there is so awful, you
have to turn off speakers. On the i3, there is only a slight delay. It looks
like this problem is related to the CPU speed and load on startup. If I try to
open a folder at startup, the delay gets worse.

I had squeeze installed before and it worked with no problems. I'm not sure
what data to collect to pinpoint the source of this problem.
