The pop noise sound like the pop noise in scenario #1376

This bug should not be related to UCM or pulseaudio.
It can easily be reproduced by aplay. Seems to be codec driver or fw or controller driver issue.

@ClarexZhou Could you use the following command to mute/unmute in playback and see if there is a pop when mute/unmute?
amixer cset name='Speaker Switch' 0and
amixer cset name='Speaker Switch' 1ClarexZhou commentedon Mar 5, 2020
@bardliao no this pop noise if using above cset instead of headset plug.
Here is the amixer contents with and without headset with UCM PR#24

Since ucm2 issue #1999, output source won't auto switch to headphone when plug in headphone. So tested it via switching to headphone manually, issue cannot be reproduced after #1897 merged. Close the bug.
