Comment 19 for bug 1846148

So, It looks like we need to set some coeff to make the internal mic work, but only Realtek engineers know how to set the coeff registers.

And do one more test for external mic:

run sudo hdajacksensetest -a
plug the headset or external mic
run sudo hdajacksensetest -a again

upload the output-before.txt and output-after.txt.
