Strange crackling noises in Wine games and winecfg sound test?
1. Edit your /etc/pulse/daemon.conf
2. Scroll down to the line that reads „default-fragment-size-msec = 10“
3. Change the 10 to a 5 and save.
4. Restart pulseaudio or reboot. Maybe. I called „sudo /etc/init.d/pulseaudio restart“ but got no output, so this might not be required.

kill pulse audio daemon or
