This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed- focal' to 'verification-done-focal'. If the problem still exists, change the tag 'verification-needed-focal' to 'verification-failed-focal'.
If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.

[Fix] Give these two cards profile name, so userspace can identify them to add addition support. In addition to that, disable non-working element and relax error handling for speaker, so there's no error left. Otherwise usb-audio driver will stop working completely. [Test] After the patch is applied, `cat /proc/asound/cards` can show correct profile name for each card. No more error can be spotted from dmesg. The audio is still not fully working yet, because it requires more work in userspace ALSA and PulseAudio. [Regression Potential] Low. Adding profile name doesn't change any code flow. The only behavioral change is error handling towards "Speaker." Becuase it actually relaxes the error handling instead of tightening, so devices that don't have this issue won't be affected.
