Is there any facility for developing an ALSA device driver in userspace? I'm particularly interested in mixer devices; my goal is to expose the Thinkpad hardware volume buttons as an ALSA mixer.

Thanks for any pointers!

The volume buttons should be supported by either acpi controls or keyboard settings. Try running showkey and seeing if they trigger keycodes. Once you have those, you could map them to a macro that adjusts volume through amixer. I know that there are applets for KDE to support the thinkpad keys, there may be others as well.
