Note that I needed sound.enable = true;
for this to persist across reboots (this runs alsactl store).
But that way camera support vanished.
oh, surprising
Cheese is for me the only application that I cannot get to work, irrespective of what I do. zoom/obs/firefox/chrome work, but not cheese.
Actually, I can get cheese to work if I run it as root, change in the preferences the app to select the good camera, and restart it. Not sure how to fix this as I get:
(cheese:13230): cheese-WARNING **: 15:47:35.995: stream error: can't negotiate buffers on port: ../src/gst/gstpipewiresrc.c(689): on_state_changed (): /GstCameraBin:camerabin/GstWrapperCameraBinSrc:camera_source/GstBin:bin36/GstPipeWireSrc:pipewiresrc1
I read this morning a notification of someone suggesting me this fix, with a link, but impossible to find it again!?
Seems like this is an upstream bug of cheese https://bugs.launchpad.net/ubuntu/+source/cheese/+bug/1978757
It's been a very long time since I last used this laptop, and have no idea how much of what I know or this Gist is still relevant. Are the current drivers able to automatically create a v4l2 device? Because if not, you might still need the v4l2-relayd stuff (create a virtual v4l2 device and automatically stream your webcam through it when an application wants to use it), unless everything has been updated to support whatever new protocol there is instead.
I do also remember the sudo alsactl init
thing, and think I ended up needing to run it every reboot but forgot to mention it.
Thanks for the answer. So the code of p-alik seems to be the minimal set of changes to apply. To avoid typing alsactl init, it seems like enabling sound.enable = true;
does a thing to preserve the setting.
Sorry I didn't mention sound.enable = true
before. :-(
@p-alik do you plan to submit your changes to https://github.com/NixOS/nixos-hardware? If yes, maybe add the sound.enable
line and a comment on alsactl init
(see also NixOS/nixpkgs#294170), and a line mentionning that cheese is broken due to an upstream bug. I also slightly improved your setting to hide the dummy camera (not even sure why it appears from the start) as it was confusing some softwares, see my changes here NixOS/nixpkgs#225743 (comment)

will do on coming weekend

Thanks
Great your mic is finally working. The browser is the only application I need camera support so far. I tried to install the browsers my home-manager also. But that way camera support vanished.
Looks like
cheese
would have the same issue on my laptop
