Hi Brad,
I tested the most current Lucid beta release on the machine. The problems do
not persist there. Audio and system in general run smoothly already since the
alpha phase.
So this is a bug in Karmic only, not in Jaunty nor in Lucid.
Do you still need me to test the upstream kernel?
Regard

Hi Alexander,
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). I
I have something I thought could be useful.
To avoid confusion, I've found a workaround and I'm only posting here in
case it helps you guys who work on ubuntu. I'm trying to get into linux
but just don't have the time.
Thus, excuse amateur posting, and let me know if I can provide more
info.

Yes, it's funny. I actually have had problems with power_save=0, a value
of 60 or higher has worked better for me. Even though I actually
experience those pops that are described in

higher values. This is definitely related to b
Ok, after an evening of perfect sound and no glitching, including a
number of reboots which didn't change that, this morning I boot up and
the sound problem has returned. Checked the alsa-base.conf file and
it's the same as I left it when I changed it, and which immediately
stopped the glitching,
I have had exactly the same bug and following the advice in that thread
fixed it perfectly for me, my audio works with no flaws whatsoever since
I changed the power_save value to 0.

Audio stutter
Hm, somehow I got rid of the problem.
After playing around with the power_save value in
/etc/modprobe.d/alsa-base.conf. I changed it to 60 and the dropouts disappear.
However when I temporarily switch back now to a value 10, it is very difficult
to reproduce the dropouts. I did otherwise not cha
Uff, wow, that was harder than necessary, trying to add an apport report to
this bug. apport-collect didn't do more than the above comment and then
aborted. And I first had to find out that I have to update apport from
ubuntu-updates to fix a bug with the apport-cli offline mode in Jaunty.
But h
@Daniel: Of course. Next free minute I have I will boot into a Jaunty
Live-CD and make apport send the information pack to this bug as well.
Then we can compare what has changed since then regarding the sound
card. Since it worked out-of-the-box in Jaunty, this might lead us to
the culprit change.
Right, -rt and -generic are very different kernels. I can't test -rt
on this hardware because of stability issues, so I have to concentrate
on the latter.

Ok, did a quick check of the situation in UbuntuStudio 9.04. Thinking about it,
the environment there is quite a bit different, especially the 64bit rt-kernel.
So I guess it would make more sense to boot into a Jaunty Live-CD and do some
comparison there.
But for the time being here my findings
Argh, I meant "some vlc and top example outputs" and "verbose output of

@Daniel: Thanks for the tips. Actually I have turned off pulse
autospawning before doing any tests for this bug report, and verified
that pulseaudio is not in the process list after killing it. (I had read

To rule out some further things:
- It does not make a difference if the 3D effects are turned on or off
- I does not make a difference if the proprietary nvidia driver is used or not
I guess the most important thing right now would be to find out if this
