Fedora with noisy audio



If at any given moment the audio is very noisy, which happens most often when using Kontact or Kmail, edit the following file


[root@amd64 ~]$ nano /etc/pulse/


and look for the following section:


### Automatically load driver modules depending on the hardware available
load-module module-udev-detect
### Use the static hardware detection module (for systems that lack udev support)
load-module module-detect


Fedora has support for udev, so edit the first line of load module to


load-module module-udev-detect tsched=0


Then restart pulseaudio or restart the computer.


[pratajo@amd64 ~]$ pulseaudio --kill

[pratajo@amd64 ~]$ pulseaudio --start
