Hi Cristian
i have a quite similar card, which use the same kernel module, and in my case, the only control which make the light turn on and off is the Master one, but by default you may have your desktop controlling the PCM for instance.
Could you please check by running the following command:

amixer sset Master toggle

Hi Cristian,

You mention in the upstream bug report that this issues existed in the upstream 2.6.25-rc4 kernel. I imagine it is then still an issue with Hardy final. Will reassign to the kernel team.

Also note that I'm opening the "linux" task and removing the "linux-source-2.6.24" task. Beginning with the Hardy development cycle kernel bugs should be reported against the "linux" package instead of linux-source-2.6.xx. Thanks.

Also closing the 2.6.20 task as this does not qualify for a stable release update - .

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 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.

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 for more information. Thanks.
