My only real problem with it at the moment is that i can't get the special mute and volume buttons to work; they beep and produce tildes but don't do anything with the sound. I checked in /proc/acpi and for volume I unfortunately see "not supported". I've googled this but most of what I have found has to do with xmodmap and xev. I'm not running X right now on this machine because (1) I tried the install the first time with gnome and my braille display totally stalled at "starting gdm" so I just decided to reinstall and leave it out for now; and (2) I tend to do a lot of my gui stuff on Mac (especially) and Windows (sometimes) so mostly I just play with the gui on linux and don't really need it right now. The right keys do show up in /usr/share/acpi-support/key-constants but I'm assuming the right keycodes aren't being used; at least that's what most of what I've read online suggests

I did ask this question on the alsa-users mailing list, some time ago.
Please find the answer I got at the following URL:
