I just tested with three TPs.

T42p -- mute, vol up, vol down all work.
T61p -- mute, vol up, vol down all work.
T500 -- vol up, vol down work. mute has no display and only mutes -- it does not un-mute as the second press does on the other two models.

I would like to figure out why there is a difference... but not sure what data should be gathered.

The behavior on the T500 = press vol up or vol down and OSD displays the message properly, press mute and the sound is muted with no OSD message displayed, if mute is pressed while the sound is muted it does not restore sound.

The behavior on the T42p and T61p is that mute, vol up, vol down display a message using OSD and the second press on the mute button restores sound.
