4. Do headset hot plug during suspended.
5.Check the Sound setting after wake up
Expected behavior
UCM works normally when wake up from suspended.

@RanderWang Please provide clues by check the error log.
RanderWang commentedon May 9, 2019
It should be a driver issue. There is a HDMI monitor connected, I don't know whether this would affect the issue.
mengdonglin commentedon May 10, 2019
@RanderWang @libinyang to check with HDMI support on CML
RanderWang commentedon May 10, 2019
The error sequence is:
(1) pcm: prepare stream 0 dir 1
(2) pcm: hw params stream 0 dir 1
(3) pcm: trigger stream 0 dir 1 start
(4) pcm: trigger stream 0 dir 1 cmd stop
// miss pcm free
(5) pcm: prepare stream 0 dir 1
(6) pcm: hw params stream 0 dir 1
error: hda dma is not free for application didn't free this hda dma by calling pcm free.
This bug is hard to be reproduced, so I can't make sure it is caused by application or ASoC.

@RanderWang
Found one way to reproduce ipc error for 0x60010000 . Same dmesg and error sof logger. But UCM still works after these steps.
To Reproduce
Terminal output
dmesg
error logger
ipcError_dmesg.log
ipcError_All_logger.log
libinyang commentedon May 10, 2019
hmm, it seems to be the pcm FE/BE resume issue. It may be caused by one Ranjani's patch. This is what I'm concerning when I reviewed Ranjani's patch. There is one argument state not precise. I will submit a patch next week after my HDMI jack task finished.
wenqingfu commentedon May 10, 2019
how often can these steps trigger the error? 100% or still intermittent? @ClarexZhou
ClarexZhou commentedon May 13, 2019
These steps can 100% trigger ipc error for 0x60010000 . But UCM still works after ipc error for 0x60010000 .
@RanderWang Need to analysis if they are same root cause.
YvonneYang2 commentedon May 13, 2019
Split the bug that 100% reproduce ipc error for 0x60010000 to #934
ClarexZhou commentedon May 13, 2019
Original UCM stop work issue still occurred twice (reproduce frequency:2/20)via below steps：

@ClarexZhou Please check if patch #936 can fix this bug or not.
ClarexZhou commentedon May 15, 2019
Error not occurred with patch #936 during daily test. Close.
