You might be able to use amixer to toggle that 'HDMI/DP,pcm=3 Jack' control.
I'll try that.
The idea with the BIOS turned out to be a dead end. The BIOS is already the latest version 1.46 (from 2018 - kudos to Lenovo for a new BIOS version seven years after the purchase); I had not remembered that I had already updated it a few years ago.

Thanks for the hint. If only I knew a little bit more about ALSA's internals ... :-)

}The speaker is probably called phantom jack because it's in-built, no jack. The value is true, as it's 'plugged' i.e. available. The Headphone's value is false, because none are plugged in. The HDMI (DisplayPort) value is also false, even though the home theater system in connected and ready to play audio (no video - projector is off)! If my interpretation is correct, then it looks as if ALSA does not see the cable being plugged in. The reason is unclear, I could imagine a buggy BIOS, though (mistakes in the ACPI tables, for instance).
I'll try to download a new BIOS.

Hi,
I wasn't sure if this maybe instead belongs into 'Desktop & Multimedia', but since that says 'Everything running on X', I figured ... Anyway, feel free to move it if my assessment was wrong.
I have successfully installed Chimaera on my old, trusty Lenovo Thinkpad X220. At the heydays of Windows 7, I used to hook it to my home theater system via the DisplayPort socket. Wenn I try this with the Devuan installation, video comes out alright, but no sound, and I cannot figure out how to activate the sound. ALSA apparently can see the DisplayPort as an audio sink.
Just in case it's relevant, the hardware ist a DisplayPort to HDMI adapter, that is plugged into an AV receiver, which is responsible for the sound, with a projector (AE-2000) connected to the receiver's HDMI output. The setup is exactly the same as it used to work with Windows 7.
The first hint that on hardware level things seem to be okay comes from aplay:
$ aplay -l

I have not figured out why it is not loaded automatically. This may be a configuration issue of PulseAudio.
By bypassing PulseAudio, I tried to use the DisplayPort audio directly. I played some MP3 via
mpg123 --output alsa --audiodevice <dev> <mp3-file>By setting '<dev>' to 'hw:0,0' it plays nicely on the laptop's speakers. Using 'hw:0,3' it looks like it is playing, but nothing comes from the home theater speakers. Could it be muted, or explicitly the volume set to zero? It seems not to, see further down. Passing anything else, like 'hw:0,1', or 'hw:0,7', mpg123 baulks at me, which makes sense.
There are proper device files for card 0 device 3, and proper entries in /proc/asound/, so superficially it looks as if in terms of ALSA everything's OK (on the other hand, this may just be the source of the 'aplay -l' data):

( 7.064| 0.000) I: [pulseaudio] protocol-native.c: Connection died.It is interesting that after this operation, mpg123 does not allow choosing an audiodevice anymore: Choosing any of 'hw:0,0' (which worked before with the built-in speakers) or 'hw:0,3' (which looked like working), now gives an error.
Even more interesting is that in pavucontrol's 'Output Devices' tab, after the forced loading a second entry appears, just as I'd expect for audio via DisplayPort. I can switch over, and the level indicator of the new entry shows the Music playing if I do. Here I can also mute and unmute, and set a volume level. But, whatever I do, there is no sound from the home theater system.
'pacmd' now lists the second sink as well, but for that one it doesn't list any port! ???
