I'm also experiencing audio stuttering and wanted to contribute my findings. I'm using Ubuntu 8.04 with the rt kernel.
First off, I think there are many sources of this problem which all result in audio drop outs, which is likely why this bug has become so confusing. I was also experiencing various issues with PulseAudio, so I have completely disabled it and am now using ALSA dmix. For this reason, I should probably be filing this under another bug, which I will do as I gather more information. In my case, the audio drop out issue does not occur with applications like MPlayer, Amarok and aplay. I also tried VLC, which suffers very slightly from this issue (which I suspect is another issue). Rhythmbox, Totem, and Sound Recorder on the other hand are really bad. Minimizing/maximizing windows causes a rather large audio drop out about 50% of the time. This lead me to believe there is something wrong with gstreamer. So I decided to try gst-launch: gst-launch-0.10 filesrc location=test.mp3 ! mad ! audioconvert ! audioresample ! alsasink Indeed, this gstreamer pipeline has the same audio drop out behavior as all the other applications using gstreamer. I also tested ogg files with a gst-launch pipeline, with the same poor results. So in this case, I think I am experiencing some issue involving gstreamer. I'll be sure to post any more info as I discover it. -- Over-optimistic buffering in PulseAudio causes underruns (audible stuttering, pops) https://bugs.launchpad.net/bugs/190754 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
