2009-04-29 17:14:18 Daniel T Chen description I hope this isn't a dupe. A few people (myself included) are experiencing odd crackling / scratching noises when using pulseaudio. This frequently happens when you try to start a new piece of music or video. Sometimes it will crackle for a few seconds, then play as normal; sometimes it will fast-forward through a few minutes of the song then start playing; sometimes it will crackle then stop entirely and I have to kill pa. Here's a URL of my output of alsa-info.sh: http://www.alsa-project.org/db/?f=44dc1549d60508bd181a03ee1c65465aa5c9024d Here's a link to the ongoing thread at ubuntuforums: http://ubuntuforums.org/showthread.php?t=1084919&page=4 I have pulseaudio 0.9.14 from the main jaunty server. ProblemType: Bug Architecture: i386 DistroRelease: Ubuntu 9.04 MachineType: Packard Bell BV EasyNote MB85 NonfreeKernelModules: nvidia Package: linux-image-2.6.28-11-generic 2.6.28-11.35 ProcCmdLine: root=UUID=36b4053e-7e48-4a1a-8666-b63058a30816 ro quiet splash ProcEnviron: LANG=en_GB.UTF-8 SHELL=/bin/bash ProcVersionSignature: Ubuntu 2.6.28-11.35-generic SourcePackage: linux Jaunty SRU information follows: Impact: Users of certain Intel8x0 and Intel HDA controllers are experiencing crackling and popping while playing audio files. These symptoms appear when the mixer elements are unmuted. These anomalies are due to buffering and clock adjustment calculations that incorrectly assume that the underlying hardware is well-behaved. Resolution/Fix: Improve the buffering and clock calculations by providing more conservative floors and ceilings. Changes are backported from linux-2.6.git and alsa-kmirror.git. Provenance is given in the commits listed below in the Changesets section. Users have fared well using test kernels from http://kernel.ubuntu.com/~dtchen/. The original proposal is available at https://lists.ubuntu.com/archives/kernel-team/2009-April/005405.html. Test case: If one's audio hardware is among the affected Intel8x0- or Intel HDA-based, simply playing music in GNOME using Rhythmbox will expose this behaviour.

Practically, users of jack-audio-connection-kit (JACK) and other native ALSA apps [not routed through PulseAudio as is the default in Ubuntu] may notice changes in jitter. Testing since Jaunty's release has revealed no regressions. -- Original bug information follows: I hope this isn't a dupe.
