Thank you for reporting this bug to Ubuntu. Ubuntu 11.04 (natty) reached end-of-life on October 28, 2012.
See this document for currently supported Ubuntu releases: https://wiki.ubuntu.com/Releases We appreciate that this bug may be old and you might not be interested in discussing it any more. But if you are then please upgrade to the latest Ubuntu version and re-test. ** Changed in: pulseaudio (Ubuntu) Status: Confirmed => Incomplete -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to pulseaudio in Ubuntu. https://bugs.launchpad.net/bugs/778852 Title: Sound is distorted sometimes Status in pulseaudio package in Ubuntu: Incomplete Bug description: Binary package hint: pulseaudio When I'm listening to rythmbox sometimes sound becomes distorted. Sometimes it is distorted when I unpause playback, but if I pause and unpause once more it becomes fine again. I found pretty good way to reproduce though: 1) Have rythmbox playing. 2) Open video file in totem 3) Close totem 4) repeat 2-3 Always, when totem opens/closes I hear a small dropout in music. But sometimes along with dropout distortion begins. And distortion finishes when I open/close totem again. I.e. I open totem - just dropout, I close totem - distortion begins, I open totem again - distortion disappears. Distortion doesn't appear 100% of the time, but pretty often. Dropout can be heard always. This problem appeared after upgrade to Natty. Before this update I never heard any distortion on this laptop. Here is an alsa debug output when I start totem and distortion begins: --------------------------------------------------------------------------------------- I: client.c: Created 19 "Native client (UNIX socket client)" D: protocol-native.c: Protocol version: remote 16, local 16 I: protocol-native.c: Got credentials: uid=1000 gid=1000 success=1 D: protocol-native.c: SHM possible: yes D: protocol-native.c: Negotiated SHM: yes D: module-augment-properties.c: Looking for .desktop file for totem I: client.c: Freed 19 "Видеопроигрыватель Totem" I: protocol-native.c: Connection died.
