Bug Description

After upgrading to
Linux buznote 2.6.24-7-generic #1 SMP Thu Feb 7 01:29:58 UTC 2008 i686 GNU/Linux
from -5 today, switching between sound from the docking station and from the laptop directly does no longer work as it used to on -5. I used to have a PCM device, a "Front" device and a binary device called IEC958 for sound output. The latter would decide if the docking station would output sound. Now I have TWO "Front" devices which apparently don't do anything and the IEC958 is still there (toggling sound from the docking station) but sound from the laptop does no longer turn on.

Linux 2.6.24-8-generic #1 SMP Thu Feb 14 20:40:45 UTC 2008 i686 GNU/Linux

also suffers of this bug.

I assume this happened after the update to alsa-1.0.16 final ?

2.6.24-10 is also affected, same symptoms.

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.

I can confirm a problem also with the Dell Latitude E6500 and docking station.

When docked, sound comes from both the laptop speakers and the speakers plugged into the docking station.

Here is the URL from the also-info script.

This bug was reported a while ago but there hasn't been any recent comments or updates. Is this still an issue with the latest Inprepid -proposed kernel, or with the pre-release of Jaunty 9.04? Refer to http://www.ubuntu.com/testing/jaunty/beta . Please let us know.
