Bug Description

Binary package hint: pulseaudio

Maybe this is interesting to you: Sound prolems were much worse under Intrepid; I couldnt watch a movie or listen to music:
When using the mouse while playing a video, especially, when (as I _guess_) some mouseover stuff happened (like pointing onto or moving over the system monitor panel applet), the sound stopped. Often within 0.5 seconds, sometimes only after 3 seconds or so.
It stopped without moving the mouse, too, but in many cases, i could listen for some minutes before the error occured. I saw some "POLLERR" in the logs. In many situations, restarting the app helped getting sound again, sometimes i needed to restart X. Rotating the compiz cube with the mouse via the key bound to "Initiate" in Rotate Cube seemed NOT to have had the same bad effects to the sound, as moving the mouse over the screen normally.

Ubuntu 9.04 (the os, with which I created the report): Video playback works fine, also playing 2 vids and/or music at the same time works good. The problem seems to happen with Skype only now: When selecting pulse audio in Skype, i get it basically working, but I hear stuttering sound and my call partner only gets scrambled sounds or noise. When selecting ALSA i have good sound for a few seconds. In the last case, my call partner stopped hearing the noise completely after roughtly 10 seconds, and sound playback stopped for me another 10 seconds or so later, too.

I am currently testing recording sound with the "Sound Recorder" appliction, while simultaneously playing 2 videos. So far, it seems to work properly, 3 minutes recorded successfully.

Skype version: (should be the most current version.) installed from the .deb file downloaded from skype's web site several weeks ago.

As advised by someone in #ubuntu+1, I installed the kernel from but it didn't make any difference.

As this is my first bug report, I want to apologize, if I left out anything important. Hopefully apport did include all you want to know.

Thank you for taking the time to report this bug and helping to make Ubuntu better. The issue that you reported is one that should be reproducible with the live environment of the Desktop CD of the development release the Karmic Koala. It would help us greatly if you could test with it so we can work on getting it fixed in the next release of Ubuntu. You can find out more about the development release at . Thanks again and we appreciate your help.

I have a new 9.04 amd64 install kernel 2.6.28-11-generic
Running the static Skype kype_static-
I see this has been a problem since Jan 09 tracing back many internet posts......
Seems neither Ubuntu nor Skype is addressing the issue ..or at least has not fixed it in 11 months..Yikes.
I have a plugin camera
Bus 001 Device 002: ID 046d:09c1 Logitech, Inc. QuickCam Deluxe for Notebooks
and the only way I could get this to work is with an assignment like such to run skype
PULSE_SERVER= /home/sqlpython/skype/skype
 The only problem would be is that with my roving laptop I would have to continually modify the ip address depending on WiFi hookup or Cat etho direct connect...
So I wrote a Bash to identify the IPaddress and run the Skype command based on the existing connection and inserting correct IPaddress as a variable..........
 Here is the Script but it does Not fix the Fact the I can not Play back any sound While Skype is connected VOIP to any other Person....
Please Fix it!!!!!
  This does not happen in my 8.04 install I get Sound Play Back with 8.04 while Skype Connected.



ifconfig wlan0 | grep "inet addr" | cut -d: -f2 | cut -d" " -f1 $1
ifconfig eth0 | grep "inet addr" | cut -d: -f2 | cut -d" " -f1 $2
if [ $1 -gt $2 ]
echo $1
PULSE_SERVER=$1 /home/sqlpython/skype/skype
if [ $2 -gt $1 ]
echo $2
PULSE_SERVER=$2 /home/sqlpython/skype/skype
