lost sound after resume from hibernate

Bug #249714 reported by balak on 2008-07-18
Affects Status Importance Assigned to Milestone
linux (Ubuntu)

Bug Description

Binary package hint: linux-source-2.6.24

I upgraded from gutsy to hardy. ABIT AN-M2 motherboard. Sound was working perfectly fine in gutsy - no issues whatsoever.
In hardy, sound is working when I start/restart. However, sound does not work after I resume from hibernate.

Two experiments tried:
1. After resuming from hibernate, I logged out and opened another virtual terminal (Alt+F1) and did 'rmmod snd_hda_intel' and 'modprobe snd_hda_intel. Logging in now results in sound working properly.
2. Adding 'snd_hda_intel' in MODULES in /etc/default/acpi-support does not help at all

$uname -a:
Linux ubuntu 2.6.24-19-generic #1 SMP Fri Jul 11 21:01:46 UTC 2008 x86_64 GNU/Linux

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.


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.

The Intrepid Ibex 8.10 Beta release was most recently announced - http://www.ubuntu.com/testing/intrepid/beta . It contains the 2.6.27 Ubuntu kernel. It would be great if you could test and verify if this is still an issue. The status is being set to Incomplete until we receive further feedback. Thanks.

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.
