(I'm the thinkpad-acpi upstream) 2.6.32.10 (and 2.6.33.1) has a lot of thinkpad-acpi fixes, but they are for real bugs in the driver, not extra functionality. I will try to submit the extra event functionality for backlight (not sound, which is what this bug is about) to 2.6.32.y very soon now that the bugfix queue is empty. 2.6.32.y still doesn't have ALSA mixer support, and it will take a while for it to be submitted to 2.6.32.y. The ALSA stuff is not working well in mute-only thinkpads yet, the firmware on the newer mute-only thinkpads changes behaviour depending on OSI(Linux), and not always in the same (or sane ;-) ) way. This results in weird behaviour and the mixer may not report properly the mute state. Using the ALSA mixer to CHANGE mute state is not working well, either. NOTE: I specifically do NOT recommend that the ALSA mixer be enabled in write mode by any distro. The driver defaults to read-only mode which can be used to get events, but the user is to use the volume hotkeys to change volume or mute/unmute. You would do well to heed that warning. If you guys backport this stuff from 2.6.33.1 (or current mainline), I recommend you change the driver to disable the ALSA mixer on mute-only thinkpads for now. -- "One disk to rule them all, One disk to find them.
