[karmic] ALSA random lags

[svetylk0]

Description: Ubuntu 9.10
Release: 9.10

Hi, I am using ALSA as default for a long time without problems, but this happened the first time when I upgraded to Karmic.

When I play mp3 [i've tryed mplayer and xmms] , I get randomly small lags, but not often - cca 1x per minute? or sometimes 1x per more minutes ...

When I play some film in mplayer, after maybe 10 or more minutes the video freezes and sound gets into a loop, which makes noisy sound :-) . When I press "q", it takes a few seconds and then mplayer exits. (I will try it again sometime to get more info about prospective error messages)

When I play some film in VLC, it does the same, except video continues without a sound ... when I turn it off I see in the console message like: "ALSA: broken pipe"

I also tried to delete my ~/.asoundrc but mp3 is still lagging sometimes .. (haven't tried films yet after deletion of this file)

mplayer actually doesn't print any message... I need to kill it :-)

but VLC prints out:

[0x8b37948] alsa audio output error: cannot write: Broken pipe

Hi svetylk0,

Please, if you are still having issues, test with the latest development release of Ubuntu. ISO CD images are available from http://cdimage.ubuntu.com/releases/ .

If it remains an issue, could you run the following command from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report.

apport-collect -p alsa-base 490743

Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds .

Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text.

Please let us know your results.

Hi Brad, now I'm on Lucid Lynx and it looks much better ... no lags have been unambiguously detected for now :-). I'll keep testing and let you know if some issue will occur. Thanks.

Update: while listening to MP3s, some little lags occured again. It seems they are less frequent than before, but maybe it's only my impression :-).
