Once it has finished building in ppa:diwic/pulseaudio-testing, can you please
do this:

Looks like you've found it Raymond. :) What happens next? Is this
something that I could fix my Precise installation myself? Or is this
something the Ubuntu Pulseaudio team could release a fix for? Or does it
need to be reported upstream?

Joel Ebel, this bug was reported a while ago and there hasn't been any
activity in it recently. We were wondering if this is still an issue?
Can you try with the latest development release of Ubuntu? ISO CD images
are available from http://cdimage.ubuntu.com/releases/ .
If it remains an issue,
AlsaVersion: Advanced Linux Sound Architecture Driver Version 1.0.24.

I reproduce this on Precise with an up to date kernel. This bug is not
fixed.

Liz Fong-Jones, please do not apport-collect to another person's report.

Christopher, Liz is a colleague of Joel's and mine, and was responding
to your request for whether this bug still affects us. The answer is
yes, and Liz was providing the information you asked for, because Joel
is no longer on the team. Can you please restore what you deleted and
treat her
Thomas Bushnell, my request for information was only addressing Joel,
not Liz, anyone who mark themselves affected, or those who are just
subscribed. As well, Linux package bugs work in a completely different
way then userspace bugs, as detailed in
Christopher, you have misunderstood. I have explained that Liz is not

Thomas, Liz, if you need me to help work around bugs in Launchpad and
broken bug policies, if you can give me login access to a machine I can
log in and run apport-collect as myself. However, in the long run,
Launchpad really should deal with this problem of turnover better.
But seriously, this
Still happening on Precise, with a DA40.

This has been happening since my upgrade to Karmic and now also in Lucid

drop the master to around 70-80% the distortion seems to go away.

I spoke too soon. This is NOT fixed in Karmic or Lucid. Yesterday I
was testing with a file that didn't use maximum amplitude. Once I
tested with my favorite overdriven audio (Eagles Greatest Hits), I
reproduced the overdriven sound on both Karmic and Lucid. Turning down
the application
The overdriven sound seems to no longer be happening on Karmic or Lucid.
Though I'm puzzled since according to my notes, I did see this in Karmic
previously, and I don't see any changes to pulseaudio in Karmic that I
feel should have fixed it. I may do some more testing with the original
There has been no activity on this bug for a while. Is this still an
issue with either Ubuntu Karmic 9.10 with latest updates installed, or
Ubuntu Lucid 10.04 alpha 3?
Thanks.
