I can confirm the same behavior in Fedora 17/18, Skype 4.1.0.20, i.e. opening pavucontrol fixes the problem which reappears after closing pavucontrol. Another interesting thing is that even if I open pavucontrol, it takes some time until the problem goes away (first 2-3 playbacks still have crackles). It only concerns the "skype system sounds", the voice quality is OK on both sides.
So, it's not an ubuntu problem but Linux/PulseAudio/Skype in general. ** Also affects: skype (Fedora) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/787772 Title: Major sound distortion, random To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/skype/+bug/787772/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
