[solved] bad sound with pulse

hi
since I updated my system last time, I hav a problem with my sound.
I use alsa with pulseaudio.

The problem is that skype has a very bad sound or sometimes no sound at all.
But I discovered a fix:
If I change in /etc/pulse/default.pa the line

load-module module-udev-detect
to
load-module module-udev-detect tsched=0

skype works, but most other aplications do not.

I have no idea which update causes this problem.
It can be any update from the last two weeks...

Can someone help me?

Re: [solved] bad sound with pulse

Skype has a problem with proper low-latency pulse resampling remove the tsched=0 again, edit your /usr/bin/skype script with an editor with root rights and prepend:

PULSE_LATENCY_MSEC=60

to the exec line. This workaround was included in earlier releases of the packages but was removed since the exact value/necessity is highly specific to one's system. This was mentioned in the post-install message however, which you should always make sure to read.
