@xiaq,
Here we are trying to solve the mute issue for Maverick & later version. Could you try to collect the alsa-info on Maverick *with* and *without* thinkpad-acpi driver loaded.
I am wondering if `modprobe thinkpad_acpi enable=0` works, this parameter prevents the alsa mixer from being initialised.
Since I have no hardware in hand, I am just doing the source-level investigation. It seems that some initialisation steps of thinkpad-acpi is affecting the behaviour of the mute function. But it is difficult to track since this driver has almost 10000 lines.
My last attempt to change the hotkey_mask is also based on this assumption.
I hope we are lucky enough to narrow down the possible hotspots. As it is hardware-related and it is not really observable, it is also possible to occur somewhere obscure.
