Bug 212771

Try to pass quirk_alias=0c46636b:047f1111.  This will make the driver applying the same quirk as Plantronics device, and the error should be gone.
If this actually makes your device working, we can cook up the proper quirk patch.

$ cat /proc/cmdline 
root=PARTLABEL=Linux_Root rootflags=subvol=@/live quirk_alias=0c46636b:047f1111

However, the same error persists and the microphone still does not work.

Err, it's the module option for snd-usb-audio.
So, on the boot options, you'll have to pass like
  snd_usb_audio.quirk_alias=0c46636b:047f1111

Ah. That removes the error message, but the microphone still doesn't work. It does work when tested on a Windows laptop. Might I be missing some kernel module? (I am using a self-configured kernel.)

Then the error message was irrelevant from the bug itself.

Please give alsa-info.sh output (run with --no-upload option and attach it to Bugzilla), as well as the output of lsusb -v for the device.

Also, as a blind shot, try quirk_alias=0c46636b:046d1111 instead.

With that, the error returns.

Hm, then try quirk_alias=0c46636b:046d084c.  This is the alias to Logitech ConferenceCam Connect that has quirk for the sample rate ep and the delay for each setup.

You're testing with a too old kernel, that's why get freq error is shown with this quirk value.  But, the delay quirk was already applied in 5.10 kernel, so essentially this doesn't seem helping the primary problem.

I have no further clue ATM.  You can try to apply the similar workarounds found in quirks.c for your device.

Thanks for your suggestions. I'll likely just wait and hope this gets fixed at some point.

Oh, BTW, when you test recording, you'd better use arecord with -Dplughw:xxx option directly without PA (where xxx corresponds to your card index).

Where can I find the card index?

/proc/asound/cards

Thanks. (I should've read man arecord and done arecord -l.)

I did. No sound for the Sonix, but sound for the Quick Cam 9000, as via Pulse.

Were you able to get the microphone working?

> Were you able to get the microphone working?

No. I just tried again with 6.6.13 and the same issue is still there.

Because of the audio issue, I've never really used it. Now, while testing, it is clear the video is just bad as well. It's just not good hardware my organization gave me. I was just using old stuff of my own. I'm going to return it and ask if they have something else, which does work with Linux.
