@libinyang please help to check first

[ClarexZhou]

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

[libinyang]

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' 0
and
amixer cset name='Speaker Switch' 1

[ClarexZhou]

@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
24headset.txt
24speaker.txt

Here is the amixer contents with and without headset with UCM PR#28
noheadset.txt
headset.txt

[ClarexZhou]

Error also can be reproduced with below steps:

1. paplay 1.wav -vvv
2. open system sound setting, select output source, to switch sources between Speaker and Headphone.

Error not seen on UCM without PR#24 or without PR#28.

Error not seen with kernel sof-dev, commit: 0f90705, contains PR #1887 + PR #1897 and FW: https://github.com/thesofproject/sof/tree/cml-010-hot-fix, commit thesofproject/sof@0ed0dba + commit thesofproject/sof@f73332e

But still has slight noise on internal speaker with same kernel sof-dev, commit: 0f90705, contains PR #1887 + PR #1897 and FW: Master, commit: thesofproject/sof@afd97708

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.
