[SOLVED] Can't get port names for headphones / speaker

I need to use a script to switch between headphones and speakers ports. I would like to use this command:

pactl set-sink-port <sink index = 4> <port symbolic name>

Hower I don't know how to get correct port (symbolic) names as stated as required in manual. All I see is pacmd list output where only "speaker" is present (I would excpect something like "analog-output-headphones").

	Ports:

		[Out] Headphones: Headphones (type: Headphones, priority: 200, available)

Any ideas how to get the corret port name?

Ports:
		[Out] Speaker ...
		[Out] Headphones ...

these are your port names, you might have to escape the space i.e.

pactl set-sink-port 4 "[Out] Speaker"

. You'll also want to use the full sink name rather than rely on the index: alsa_output.pci-0000_00_1f.3-platform-skl_hda_dsp_generic.HiFi__hw_sofhdadsp__sink

That "weird" designation just means that your card is setup using ucm configuration files which I'm also not entirely sure as to the technical reason why these started to be used that way for newer cards, presumably to be more portable to different systems/APIs than the standard designation pulse would do.

Oh gosh, I do feel dumb, I've tried many combinations but not most forward one.

You're my saviour! Thank you, V1del, have a great day!
