Bug Description

Binary package hint: pulseaudio

On my Asus Eee PC 900HA using Ubuntu 10.04 RC, listening to music is nearly impossible with stuttering occurring regularly even when no other applications are running. I'm attaching a pulseaudio log to show you what's going on.

This looks like a sound driver bug. Can you reproduce this symptom using linux-alsa-driver-modules-$(uname -r) from ppa:ubuntu-audio-dev?

I just installed that package, and while it seems like the stuttering is less frequent, it's still occurring, but I've only listened to music for a few minutes with the new alsa drivers installed... a long period of listening may prove that the problem is still just as bad as before.

Yes, I can say for certain now that the stuttering is still just as bad as before.

Can you try adding the following line to /etc/modprobe.d/alsa-base.conf and rebooting?

options snd-hda-intel position_fix=1

Please a verbose pulse log and dmesg with position_fix=1 active.

Well yesterday seemed to be a bit of a fluke... today, the most I can seem to reproduce is occasional popping... nothing nearly as severe as yesterday.

The following workaround seems to have done the trick for me:

System: Ubuntu 10.04 amd64

File: /etc/pulse/default.pa
Add " tsched=0" to the following line:
load-module module-detect

Even after adding " tsched=0" I still have stutters.

A couple of things to try:

1. Try installing linux-alsa-driver-modules-2.6.32-22-generic from the ubuntu-audio-dev PPA, http://launchpad.net/~ubuntu-audio-dev/+archive
If installing this package and rebooting doesn't help, then try adding the following line to /etc/modprobe.d/alsa-base.conf
options snd-hda-intel position_fix=1
Reboot after you make this change.

Please report back with the results.

Luke Yelavich,

I've already tried your suggestions, they don't fix the problem for me -- see my comment (#29) on Bug #551949:
https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/551949/comments/29

(Re the workaround in my comment #14 above: The stuttering/skipping returned a couple of days later.)

Ok, instead of position_fix=1, try changing that to enable_msi=1 and report back with results.

Did this and rebooted. No change in behaviour, the problem persists.

Closing that outdated report as EOL has been reached long time ago
