Bug Description

Hello,
the problem appears mostly on the start from cold and only sometimes at restarts:
When the sound is not muted at start:
i hear nothing, when i turn the sound off i hear the sound but very silent.
After a while esd using sometimes ~80% cpu.
When the sound was muted at start:
turning the sound on helps; After a while i hear only every second sound and every music sounds corrupted. The problem comes randomly, and sometimes it disappear after hours without restart.

i have two mixers under master:
Alsa mixer
and oss mixer

hello,
i will add attachments next time it appears, but i want to add something to the description.
Often when the sound is at start silent it helps to play with the master volume, then i hear something and then with the pcm volume, then i have sometimes full volume.
Sometimes not, when that happens i mute and unmute the sound few times with xine and make it louder with xine.
mosttimes after this the sound works.
So it seems that the problem is that the soundpanel works not proper...

i use gnoe ant the volume controll panel

Beginning with the Hardy Heron 8.04 development cycle, all open Ubuntu kernel bugs need to be reported against the "linux" kernel package. We are automatically migrating this bug to the new "linux" package. However, development has already began for the upcoming Intrepid Ibex 8.10 release. It would be helpful if you could test the upcoming release and verify if this is still an issue - http://www.ubuntu.com/testing . If the issue still exists, please update this report by changing the Status of the "linux" task from "Incomplete" to "New". We appreciate your patience and understanding as we make this transition. Thanks!

The Ubuntu Kernel Team is planning to move to the 2.6.27 kernel for the upcoming Intrepid Ibex 8.10 release. As a result, the kernel team would appreciate it if you could please test this newer 2.6.27 Ubuntu kernel. There are one of two ways you should be able to test:

1) If you are comfortable installing packages on your own, the linux-image-2.6.27-* package is currently available for you to install and test.

--or--

2) The upcoming Alpha5 for Intrepid Ibex 8.10 will contain this newer 2.6.27 Ubuntu kernel. Alpha5 is set to be released Thursday Sept 4. Please watch http://www.ubuntu.com/testing for Alpha5 to be announced. You should then be able to test via a LiveCD.

Please let us know immediately if this newer 2.6.27 kernel resolves the bug reported here or if the issue remains. More importantly, please open a new bug report for each new bug/regression introduced by the 2.6.27 kernel and tag the bug report with 'linux-2.6.27'. Also, please specifically note if the issue does or does not appear in the 2.6.26 kernel. Thanks again, we really appreicate your help and feedback.
