I have a problem with Skype in Ubuntu 13.10. When I try to make a call or when any application sound plays, my laptop starts making high pitched noises that won't stop until I quit Skype.

Do you have any ideas?


So, basically you got "Skype generating neverending scratchy white noise sound for notifications"

Edit /etc/pulse/default.pa and change from the code from:

load-module module-udev-detect


load-module module-udev-detect tsched=0
  • This worked for me. I hope it keeps working. I will update if it is not consistent. – Sileria Feb 21 '14 at 16:40
  • This has (severe) side effects including echoing in moc, overspeed play in chrome. The other answer doesn't have these side-effects – sehe Jun 20 '14 at 10:10

user1039704's answer did not work for me but this command did:

sudo sed -i 's/^Exec=.*/Exec=env PULSE_LATENCY_MSEC=30 skype %U/' /usr/share/applications/skype.desktop

  • Also seems to work for other problems - in my case apparently wrong sampling rate. – Thomas W. Oct 29 '18 at 21:28

I struggled with high pitched sound in skype from middle of 2018.

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


resample-method = speex-float-10

won't help anymore

Explicitly set in /etc/pulse/daemon.conf

default-sample-rate = 48000
alternate-sample-rate = 44100

(default-sample-rate already set beforehand)

And voula! Skype usable again!
