Ok, I've gotten the first feedback. I ve asked the
users to test the following after running the 4 suggested
hda-verb commands:

1. Speakers
2. Headphones output
3. Internal mic.
4. Headset mic. (using a phone headset with builtin mic with a single T-R-R-S connector)

I've got feedback from a user with a UX533FTC-A8221R laptop:

1. Speakers: works
2. Headphones output: works
3. Internal mic: doesn't work
4. Headset mic: works

So things are looking ok, but we still have some
work to do to get the internal mic to work.

Kailang do you have any suggestions for getting the
internal mic to work?

Regards,

Hans
