kernel 2.6.22-10 breaks sound on lenovo c200 (regression from 2.6.22-9)

[Peter Maydell]

Binary package hint: linux-image-2.6.22-10-generic

My Lenovo 3000 C200 laptop runs gutsy, primarily because feisty doesn't support the sound hardware in it. Tribes 3 worked fine for sound. However, I did a dist-upgrade last night to get the most recent gutsy packages, and there is a regression: sound has stopped working. If I boot with the old kernel (2.6.22-9) then sound is fine; however with the new kernel (2.6.22-10) nothing plays. Apps like xmms don't claim to be unable to play, but there is no sound output. Also alsamixer shows a greatly reduced set of mixer controls.

Alsamixer reports the sound chipset as "Card: HDA Intel; Chip: Realtek ALC861-VD".

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!
