doing time play /usr/lib/openoffice/basis3.2/share/gallery/sounds/ok.wav I see the same similar result on 10.10 maverick meercat with different sound hardware from what you are using. when I stopped pulseaudio from running, the delay went away unlike you, I did not experience a sync problem when playing video files. However my sound input was unusable due to an approx 1 second delay and choppy/jerky sound on VoIP. killing pulseaudio also solved this problem. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/582600 Title: Ubuntu Lucid / PulseAudio Alsa-Plugin : 2 sec delay -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Oli, Before I saw this bug, I did upgrade from Karmic to Lucid (rather than installing Lucid on an empty drive), and am still running Lucid, as noted in my original report in 591003 (but I am now running 2.6.32-24-generic): ProblemType: Bug DistroRelease: Ubuntu 10.04 Package: sox 14.3.0-1.1build1 ProcVersionSignature: Ubuntu 2.6.32-22.33-generic 2.6.32.11+drm33.2 Uname: Linux 2.6.32-22-generic i686 Architecture: i386 Date: Mon Jun 7 17:38:46 2010 ProcEnviron: PATH=(custom, user) LANG=en_US.UTF-8 SHELL=/bin/bash SourcePackage: sox Karmic ran ok, and Lucid (with pulseaudio) has the slow audio bug for me. It is possible that a fresh install, rather than an incremental install might fix my problem, but that means something is wrong with the incremental install. (Is it possible that I should try to reinstall some packages?) I still have the bug as before, where playing a sound file results in an extra delay of about 2 seconds or more. This is a problem when I have code that uses /usr/bin/play on several sounds in a row, and I expect them to play in rapid sequence. If you play /usr/lib/openoffice/basis3.2/share/gallery/sounds/ok.wav and it is supposed to take .4 seconds, but instead it takes 3 seconds, if you play it 5 times, it takes 15 seconds instead of 2 seconds, which makes for a poor user experience. -- Ubuntu Lucid / PulseAudio Alsa-Plugin : 2 sec delay https://bugs.launchpad.net/bugs/582600 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

Hi Oliveiro, Welcome back.

[Bug 582600] Re: Ubuntu Lucid / PulseAudio Alsa-Plugin : 2 sec delay
I'm getting this problem, too. Pretty much anything that uses alsa (and therefore pulseaudio through the alsa-plugin) for me has a roughly 30 second delay. This happens with flash, as well as the native Enemy Territory: Quake Wars port, as it uses alsa and is unlikely to ever be updated for pulse-audio. This makes sound on 10.04 virtually useless most of the time for me, whereas sound worked reasonably well in 9.10. -- Ubuntu Lucid / PulseAudio Alsa-Plugin : 2 sec delay https://bugs.launchpad.net/bugs/582600 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

Hello Daniel, I read many of your posts around here ;-) Well thank you for your answer, but as I wrote in my first post, I already tried ppa:ubuntu-audio-dev... without success. To follow your advice, and to double-check, I did a fresh install again, updated with lucid-proposed activated, added ppa:ubuntu-audio-dev and installed linux-alsa-driver-modules from there (Kernel is 2.6.32-22-generic). Failed again... I notice that logs change : rewind messages and also memblockq.c messages appear, they did not before i used ppa:ubuntu-audio-dev. But I still get an approx. 2 sec delay on the audio. And the message source-output.c: Created output ALSA Capture occurs last, after the message sink-input.c: Created input ALSA Playback In Karmic, it was the contrary. I still don't if it's related.

And also, here's the same syslog but under Karmic: (where the 2 sec delay does NOT happen) I see a lot of differences now, but I don't know how to interprete them For instance lot of: alsa-sink.c: Requesting rewind due to latency change or memblockq.c: memblockq requested: and some alsa-util.c: Maximum hw buffer size is 341 ms that do not occur in lucid... What's strange, it's that under Karmic there are many messages from pulseaudio sink-input.c creating, then freeing inputs ALSA Playback before succeeding. And also another difference I observe, is that in karmic source-output.c: Created output ALSA Capture occurs before sink-input.c: Created input ALSA Playback In lucid the order is inverted : first sink-input, then source output. And all protocol-native.c: Final latency are the same in Lucid and Karmic. Finally, I also notice a message in Karmic, which is not in Lucid protocol-native.c: Early requests mode enabled, configuring sink latency to minreq. But again, all final latencies are equal (?!?)
