Interestingly, I looked deeper and even before I wrote the comment
above, the patch had already been added to the 5.10 and 5.15 stable
trees. It seems that for some reason it wasn't added to the 5.4 tree.
Weird...I wonder if it doesn't cleanly apply or something.

Technically this fix hasn't actually landed in an official kernel yet.
Right now they are in the part of the cycle where they release weekly
release candidate builds of 5.17. This fix first showed up in v5.17-rc3.
I would expect v5.17-rc6 to be released today, and the final 5.17 to be
released in
Can anyone tell me how come the patch is not integrated with the
mainline kernel yet?

Thank you very much for the workaround! Without it, the bug is still
present here, too.

After installing kernel 5.0.4.100 the bud is still there - is the bad
news. The good one is that trick from macg3 still works.

Thanks to macg3, the workaround you suggested works for me on kernel
5.4.0-99.112. There is one correction. The name of the audio driver is
snd_usb_audio and not snd-usb-audio. So in my case after a fresh boot
the webcam did not work, and after executing:
sudo modprobe -r snd_usb_audio
sudo
Thank You macg3, I'll try this solution when I'll have time to
experiment. If it works in my case i will make you know. Thank you
again :)

I believe this bug was caused by this commit in the kernel:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/sound/usb/quirks-
table.h?id=48827e1d6af58f219e89c7ec08dccbca28c7694e
A patch to fix the issue was committed to the kernel 11 days ago:
I've just tried 5.4.0-99.112 it still doesn't work (I mean the camera [lsusb:
Bus 002 Device 005: ID 041e:4095 Creative Technology, Ltd Live! Cam Sync HD
[VF0770]). I will not report the bug again. Nothing happens. I roll back to
5.4.0-91
I can't find any hardware problem so the onlu solution
@bonej079 I've tried every kernel from the 5.4 line and can confirm that
Creative Live! Cam Sync HD (VF0770) doesn't work on any of them after
5.4.0-91. Once I run the system using 5.4.0-91 it works like a charm so
no hardware failure for sure.

I use Ubuntu 20.04. Latest kernel with working webcam is still 5.4.0-91
for me. Just tried the new 5.4.0-97.110 and webcam is not working as in
all other kernel versions after 5.4.0-91.

@Piotr: Maybe provide 'sudo lshw'. I have one machine with the same
issue for this cam, another without the issue. Perhaps there's a common
piece of HW causing this.

I've tried everything I could but camera still doesn't work with the new
kernel. Perhaps it is some hardware failure :(

Thank you bonej079 for your answer. I've installed the kernel from
Mint's update and nothing have changed with my camera - does mean it
still doesn't work. If in your case it works thus mean I need to look
for a solution. If I find any I will make know it over here

Hi @orsei,
Yes, it is working now. However, the version reported in Mint's update
history is is 5.4.0.97.101. Full /proc/version
Linux version 5.4.0-97-generic (buildd@lcy02-amd64-032) (gcc version
9.3.0 (Ubuntu 9.3.0-17ubuntu1~20.04)) #110-Ubuntu SMP Thu Jan 13
18:22:13 UTC 2022
and the camera
I have tested two of such cams each on two different machines using the same
kernel. On one machine the cams worked, on the other not.
What information is needed for further analysis?

@bonej079. I have installed it and I have reported bug again. Are you
sure that with 5.4.097 110 it worked?Perhaps you have different type of
the camera?
