Standard controls don't seem to work well both for audio record and playback from Youtube, etc. and mic input from Audacity, Zoom, Skype also fail even when I use system settings, Kmix, Also Volume Control to adjust them.
This has been an episodic issue with this Transformer 3 Pro laptop under Neon for a long time, and I have not figured it out. In this virus threatened era it is troubling to have a Linux issue like this unsolved.

I hope to use Zoom on Monday afternoon Calif time for a meeting.
Last attempt I was able to get a workaround with a USB mic on a headset, but that is also not reliable.

Today I can use Skype under Win 10 (but not Skype under Neon) and may line up a trial with Zoom after I download it to Win 10 so I have a workaround.

I read a bunch of past postings on other forums and did the following to get some sense of my setup, but I am not able to interpret it all.

I will go across town and check back again in about an hour and check in over the weekend around the clock.
