Hello,
I've hit an issue since upgrading to Zoom 5.10.4 (or it appears) that rebooting nor removing and re-installing Zoom fixed.
Historically, I could set my System Audio out to my "Headphones - Built-in Audio" and my Mic to "Headset Microphone - Built-in Audio" and leave Zoom at "System Settings" for both and it would just work.
After a recent upgrade, the "Headset Microphone - Build-in Audio" doesn't work or will work briefly if I set Zoom to use another Mic input setting and flip back to "System Setting". The weird thing is I can see the volume bar for what's being picked up by my headset Mic move as I talk in the Setting -> Sound in Ubuntu, but in the "Test Audio in Zoom it will quit and the input volume bar will show absolutely nothing. Switching to another device and back tends to resolve this for about 5 seconds.
I also noticed under the Zoom audio settings, my "Headset Microphone - Build-in Audio" no long appears in the "Select Mic" option dropdown, nor does the "Headphones - Built-in Audio" appear in the Speaker selection drop down although *both* appear in the Ubuntu audio selections list. If I plug in my USB Webcam I can see that show up in both my Ubuntu sound settings and Zoom as a mic input, and the same holds true for my USB Speakers.
I can't figure out where this issue is coming from so I can't resolve it, and it's extremely annoying not being able to use my headset to chat in Zoom sessions, anyone have any ideas/solutions?
