So, I've done some first tests and I can confirm the following: Thinkpad T440p / Debian 10 / R 14.0.9 (Development) / kmilo-trinity & legacy HDA Intel PCH FN - F1/F2/F3: mute on/off is shown, but no effect Sound 100& / 90% appears but no effect There are some problems with HDA Intel PCH and HDMI: some time kmix tries to control HDMI so HDA Intel PCH does not react. Thinkpad X220 Tablet / Debian 9 / R 14.0.5 (Development) kmilo-trinity & legacy Fn-Home / Fn-End work (screen backlight) Fn- sound keys (play, stop, etc...) don't work Sound +/- button (physical) work Mute button mutes but does not unmute. It does print "unmute" on screen, but I need to use kmixer to get sound back. Thinkpad T400 / Debian 9 / R 14.0.8 /kmilo-trinity & Legacy Fn-Home / Fn-End work (screen backlight) Fn- sound keys (play, stop, etc...) don't work Sound +/- button (physical) work Mute button mutes but does not unmute. It does print "unmute" on screen and kmimx icon shows mute, but I need to use kmixer to get sound back. I did not test other buttons.
