Start Rhythmbox / Totem 2. Rapidly Start and Stop music/video What is expected to happen: The audio (flash-player, Totem and Rhythmbox) should output their sound. What actually happens: If music/sound is played I hear something like "fast forwarded" bells (high pitched randomness) Pulseaudio -vvvvv: see attachment. How to work around (get sound working again): 1. Shut off all audio-sources. 2. Unplug headphones 3. Mute sounds 4. Unmute sounds 5. Plug in headphones 6. Mute and Unmute sounds When did I register this issue the first time (I don't know if it regressed at this exact date but in 12.04 this bug never happened): 09 March 2013 (I'm updating and rebooting daily) ProblemType: Bug DistroRelease: Ubuntu 13.04 Package: pulseaudio 1:3.0-0ubuntu4 ProcVersionSignature: Ubuntu 3.8.0-11.20-generic 3.8.2 Uname: Linux 3.8.0-11-generic x86_64 ApportVersion: 2.9.1-0ubuntu1 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: octavian 2379 F.... pulseaudio /dev/snd/pcmC0D0p: octavian 2379 F...m pulseaudio Date: Sat Mar 9 12:07:03 2013 EcryptfsInUse: Yes InstallationDate: Installed on 2012-12-04 (94 days ago) InstallationMedia: Ubuntu 12.04.1 LTS "Precise Pangolin" - Release amd64 (20120823.1) MarkForUpload: True PulseList: Error: command ['pacmd', 'list'] failed with exit code 1: Daemon not responding.
