Crackling sound

[Sebastian Breier]

Version: Intrepid Alpha 3
Machine: Dell Inspiron 6400n
Audio device: Intel Corp 82801G (ICH7 Family) High Definition Audio Controller (rev 01)

I have constant crackling when hearing sound.
The crackling/static noise stops when sound stops, after some time.

I'll try to get better data on this later.

I confirm this issue, I only have this problem playing games. Media players like banshee and amarok are doing just fine.

This problem has been resolved for me by a fresh install of Intrepid Alpha 4.

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.

This bug has been fixed for me, how about you Sebastian?

Niels: No problems here. Seems to work in latest daily-live.

Per a decision made by the Ubuntu Kernel Team, bugs will longer be assigned to the ubuntu-kernel-team in Launchpad as part of the bug triage process. The ubuntu-kernel-team is being unassigned from this bug report. Refer to https://wiki.ubuntu.com/KernelTeamBugPolicies for more information. Thanks.

The symptoms sound exactly like your output PCM audio being muted. See https://bugs.edge.launchpad.net/bugs/272321
