Bug Description

[Impact]
Users plug a headset to this AIO and select headset-mic from UI, but
can't record any sound from the headset-mic.

[Fix]
The root cause is the driver return a wrong type of the headset, need
to add more delay in the determine_headset_type(), so backport that
patch to ubuntu kernel.

[Test]
Booting the system with patched kernel, plug headset and select
headset-mic from UI, could record sound from headset-mic, we tested
more than 10 times, all worked well.

[Where problems could occur]
This could make the user experience a small delay from pop-up dialogue
when plugging a headset, but the delay is less than 1s and the delay
is not much longer than other codecs, QA think it is acceptable.

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. Thank you!
