I have recently acquired a Corebooted Lenovo ThinkPad T440p from minifree, and it is awesome except for two things:
- Fn in the lower left and Ctrl next to it, instead of Ctrl in the lower left. Oh well.
- No audio over HDMI. This is more than annoying and impedes our ability to enjoy movie night.
I thought it was maybe because I had an Apple miniDP->HDMI cable, so I bought a generic one, but it still doesn't work.
Audio settings recognize that there is an audio device on the HDMI port, but when I try to use it, mpv and vlc both just speed through the video with no audio output and mpv says "Audio underrun detected".
I'm finding surprisingly little about this on the web so far. I would have expected a distinguished old model like this to Just Work and failing that having a very well documented workaround to make it work.
I'm using Debian and KDE. Any ideas?
