I don't think the issue was powertop in the end, still trying to figure it out. If someone is experiencing the same, please do tell. I'm using pipewire 0.3.56.

It seems like any run of powertop --auto-tune during boot is enough to throw the sound off (playing through speakers will stop after a while). You don't need the sof kernel either, upstream works fine, but you can't use powertop --auto-tune, at least on my system. If someone has found a way around this, please do tell...

I wonder if requiring pipewire to keep it active is not enough to "solve" that (but I guess it's counter intuitive for battery life)
example how to keep it open

If you're on Gentoo, the fol4 overlay has ebuilds with ipu6-drivers and ivsc-driver. You still need to fix userspace and firmware yourself, but then at least you have an easy way of rebuilding modules.

They don't check if you have the required CONFIG set yet, so look out for depmod symbol errors. You might need to enable some media devices (e.g. IPU3) to make the kernel include all dependent libs in the build.

Seems like zebra-ok on github was successful in building the modules with dkms using ubuntus srpms: https://github.com/intel/ipu6-driver/is … 1191848414
So with that method of building the module, I guess there's no need for that v4l2loopback workaround. Someone should test if it works properly, I'm a bit fed up with this now...
Edit: Sorry I didn't see the previous post, I had the tab open

Have you found a configuration to make the webcam work without having to run the gst-launch command manually before apps can access the camera?

Hi Mads,

first of all thank you very much for your efforts so far. I am now at the same point as you with the gstreamer error message. After I run the modprobe and gst-launch I still get:

The modprobe command for the v4l2loopback segfaults if I don't boot with kernel parameter ibt=off but with it gets loaded fine.

Kernel messages look good so far except for the "set secure mode" error:

Even an strace did not reveal anything useful at least to me.

I am out of ideas. What am I missing?

@sxw The sensor kernel module is missing. Look at my output, there is "ov01a10", too

How did you build the modules? After using vicamos repo and applying their patches for Ubuntu, and afterwards building first the ivsc, then the ipu6 with dkms, it worked.

Oh, indeed. Good point. I checked the module tree and found the ov01a1s module what is appearently the wrong one. Maybe I have to go back and check if I patched the sources correctly.

When you are talking about "vicamos repo" you are referring to https://github.com/vicamo/ipu6-drivers/ … inst-v5.18 ?

Thank you!

No, the reasing I said that was due to a misunderstanding. I thought it was working with the ubuntu provided drivers, but they were the same in the end.

So I still use gstreamer. I actually have started with using gstreamer for other webcams too, because cheap webcams often only give the best resolution when using codecs like MJPEG, and you can't get browsers to use that. But by using gstreamer you can convert it to something that the browser accepts, thus you end up with a video stream that is a lot better.

@sxw I had exactly the same output as you.

But running

journalctl -k --grep=ivsc

told me that that actually ivsc-firmware hasn't been installed properly. So instead of copying to "/lib/firmware/vsc" one should copy it "/lib/firmware/vsc/soc_a1_prod/" and add corresponding "_a1_prod" suffixes to the files. See the notice for production platform.

after that running "gst-launch" with sudo did the trick for me!

plant34 · 2022-08-09 22:52:17

@sxw
Check the last page, I linked the launchpad repos from vicamo.

@Mads
But how does Ubuntu solve it? Do you also need to run a command on the terminal before you plan to use the webcam?

Nicolas_CoderVie · 2022-08-10 14:07:01

Hello all and thank you for efforts !

my camera currently works on my Dell XPS 13 Plus. :-)

I'm sharing my steps, maybe it could help someone else (i hope so).

1) i followed procedure described by sachkris

NB : compile linux kernel was mandatory for me, because of error with other ways tested

2) i followed feedback provided by Dell support and available here : https://bugs.launchpad.net/ubuntu/+sour … omments/40

NB : i'm not using Arch but KDE Neon (ubuntu LTS + latest KDE Plasma)

Currently i dont know what made my camera working, because i first tested dell procedure (found before Dell reply feedback) and it didn't work.

So maybe some binary copy + dell procedure + reboot could explain it.

It's in french, but i made a step by step procedure to help other Dell XPS 13 Plus owners right here : https://coder-pour-changer-de-vie.com/d … plus-9320/

NB : the bash step could help, i wrote a bash to update .Konfig and Makefiles in one step.

Have a good day !
Nicolas.

I'm not sure, but I thought that was the case..? Do anyone have the opportunity to test with the Ubuntu OEM image and see?

Finally, I got it!

It indeed was the ov01a10 module that was not build because I kept trying the out-of-kernel-tree build variant. Doing the in-kernel-tree variant did the trick.

Thank you very much to all of you.

Another post in this saga. I previously mentioned that I got sound freezes if I used powertop --auto-tune. After a series of tests, I found out that the triggering setting was if I enabled powersaving on my wifi card. Really strange. If I enable everything with powertop _except_ powersaving on my wifi, the sound doesn't freeze anymore.

Posted about it here (and the script I use for applying powertop settings is there too): https://github.com/thesofproject/linux/ … 1214373478
