Description
Describe the bug
No volume controller for DMIC16/32
To Reproduce

- alsamixer, press F4 to check Capture items.
Expected behavior
Should support volume controller for DMIC16/32

Now DMIC 32 volume can be adjusted via PGA 10.0 on CML laptop.
But still no way to adjust volume for DMIC16

@libinyang @singalsu Please evaluate if we still need PR #1271 for the 16khz DMIC, which applies passthough pipeline for this DMIC and so no volume control.

#1293 is submitted for this issue

@ClarexZhou lack of volume control is not a firmware issue, please rise driver issue on linux repo.
singalsu commentedon Apr 23, 2019
@emilchudzik Why linux/driver issue, would this be a topology issue?
ClarexZhou commentedon Apr 23, 2019

@singalsu Emil meant that it's not a firmware issue, but yes, it can be topology issue, so we may keep it open because topologies are in this repo, just someone from driver team has to modify them.
emilchudzik commentedon Apr 23, 2019
Using alsamixer volume control starts driver to send suitable IPC to firmware. So if there is no such volume control, then firmware can't receive IPC.
Lack of volume control issue should be checked by driver/kernel team. I'm not sure if it is topology issue.
jajanusz commentedon Apr 23, 2019
I see you made 2 PRs related to this issue. I guess this one is the right one: #1293
libinyang commentedon Apr 23, 2019
Yes. #1293 aims to fix this issue.
