[SOLVED] No sound through DP++ to HDMI, no HDMI device option (KDE)

Hello, I am running Arch Linux 5.16.14-arch1-1 on a Lenovo Thinkpad X230T.

I am using a passive adapter to convert DP to HDMI for an external monitor. The DP port is DP++.

I cannot get the HDMI sound device to automatically appear in the KDE system settings and thus, I cannot switch to the HDMI output through the KDE UI.

Here is the output of

pacmd list-cards

1 card(s) available.

                                device.icon_name = "video-display"

The only way to switch to the HDMI output is to manually set it with:

pacmd set-card-profile alsa_card.pci-0000_00_1b.0 output:hdmi-stereo

Are there any packages or settings I am missing to make this work through the KDE UI?

Re: [SOLVED] No sound through DP++ to HDMI, no HDMI device option (KDE)

Which KDE UI are you looking at? With that kind of cards output you definitely should have a relevant profile selection in the "extended" system settings UI of plasma-pa (and for that matter, in the hamburger menu if you just check the plasmoid/the sys tray integration)

Both in the System Settings (systemsettings) and the Audio Volume integration of latte-dock. I am using latte-dock and not the usual KDE bar.

Can you post a screenshot? Are you using KMix or plasma-pa? iirc KMix profile selection was right clicking on the card control, but haven't used that in a while in favor of plasma-pa

I had both KMix and plasma-pa installed for some reason, I uninstalled KMix before starting to troubleshoot this so I am only using plasma-pa now.

Here is the screenshot with the external display attached without the manual fix:

Here is after I manually switch it to HDMI with pacmd:

Yes, and if you click on the profile drop down, that doesn't work/show the HDMI profile? It should and does so here and that would be the analogous action to you manually running the card profile command.

Oh yes, silly me. I was expecting a second Playback Device to appear as it does on my desktop.

I didn't think of changing the profile in the dropdown, now it makes sense since it is the same output device and I just need to change the output profile.

Just another case of PEBKAC.

Thank you very much, sorry for taking up your time. Marking as solved.

On your desktop it's a completely separate card. You can technically manually allocate a profile that shows both rather than doing the switch via the profile logic, but that requires a change in the pulse config files.

Yeah, that is what confused me. No need to go through that hassle, I just needed an easy way to switch from the UI. Thanks again!
