I finally had time to investigate the issue. It looks like that as of 11.5, the DesktopVideoHelper.service has to be running for the capture card to work properly.

fyi, upstream forum issue thread: https://forum.blackmagicdesign.com/viewtopic.php?f=12&t=144876

About a month ago I had sent in my card to their technical support team, thinking it might have been a hardware issue. The other day I finally heard back from them, and they said it was working on Windows. They said they did not have a Linux machine to test with (despite advertising Linux support on the box) and were not able (allowed?) to run a live DVD. They are now shipping it back to me.

@scaramanga I just coincidentally found out that the drivers are currently broken (I barely use the card) and therefore found your comment. Thanks for the heads-up & contacting upstream! :)

Short update: After almost a week Customer Support told me they won't help with Linux "due to the high level of user customisation and configurability", but referred me to the Developer Support team.

There they actually helped and provided a fix. It sounded like there should be an official update to the driver some time soon, but they didn't say a date.

Yes, the module doesn't build on 5.13.5-arch1-1 and unfortunately I'm not sure I can patch this error myself.

I suggest you to stay on LTS and report the error to blackmagic support.

the dkms modules don't build on 5.13.5-arch1-1, either. Running off of LTS for now.

No device is recognized for me after upgrading the kernel from 5.12 to 5.13.4-arch1-1. Might be a regression in the kernel.

For now I have to fall back to LTS. Did anyone else experience that?

Oh yes, I tested it with that, too. I also tried the card in Linux Mint, and on a different PC running Ubuntu 21.04, and then the first PC again but I had replaced Linux Mint with Ubuntu 20.04 LTS. Nothing but black capture with all of them, with a docked Nintendo Switch attached to it via HDMI. This may be a faulty unit, though the seller said it was never used. I'm corresponding with BMD now.

Is the DesktopVideoHelper.service enabled and runnning ? I remember having weird issue like that when it is not.

Otherwise I won't be able to help you much. I don't own a blackmagic capture card anymore, my old one broke.

I can't get my Intensity Pro 4K working. Desktop Video Setup detects it just fine (I wish this included some troubleshooting utility) but OBS doesn't see it. Here's where blackmagic shows up in dmesg:

blackmagic_io: loading out-of-tree module taints kernel.
blackmagic_io: module license 'Proprietary' taints kernel.
blackmagic_io: module verification failed: signature and/or required key missing - tainting kernel
blackmagic-io 0000:05:00.0: enabling device (0000 -> 0002)
BlackmagicIO: Intensity Pro 4K as blackmagic!io0 [0000:05:00.0]
BlackmagicIO: Initialised serial driver for blackmagic!io0

I could try the LTS kernel, but the drivers are being initialized, so maybe that's not the issue? What else should I try? I've tested /dev/video0 through /dev/video3 and found they were my other video devices (Index cameras & webcam). You'd think this would be /dev/video4 but it doesn't exist. EDIT: Using linux-lts didn't help. EDIT2: Neither did using Linux Mint. Using Media Express there just shows black. I'll try another PCIe slot. EDIT3: That didn't work either. I've emailed BMD support.
