Let's tackle this mess bit by bit because I feel like there's at least a dozen problems mixed and minced together.
> Distro: MX-21.1_x64 Wildflower You submitted this bug report to the Debian BTS (bug tracking system) while running MX Linux. Even though it claims to be using the Debian archive (thus, Debian-based), it may come with completely different configs on top of the base system. They have their own bug tracker: https://bugs.mxlinux.org/ > I had installed zoom and it was working fine then in June I found out when I > go to share screen I lose audio and sometimes got message driver not > available. Zoom is not available in the Debian archive (and will never be since it's a proprietary software). You should contact their support: https://support.zoom.us/hc/en-us/search#q=linux&t=All&sort=relevancy > I followed the direction on Linux mint website to localize problem. What direction? Which website? Again, Linux Mint is a completely different distribution with its own community. > I was able to repeat problem on different machine. What machine? Windows? Mac? Vague. > When changed desktop problem went away. >From what to what? Where did the problem go? > I tried Budgie, Mate and a friend tried Cinnamon they all work. None of these names start with 'X', end in 'e' and have 'fc' in the middle. What constitutes work here? > I think it was a security update. Security updates seldom introduce new features or touch the existing ones. Even if one did so, we still have point 2: Zoom is not available in the Debian repos. > It also showed up in the MX usb witer if opened from file manager it loses > the iso you want to write. What is it that also showed up? MX usb witer or whatever that is doesn't exist in Debian. Which file manager? > These both showed up at the the same time. Who or what are both? Where did they show up? > This one is a small problem that is nothing more than annoyance but it might > point to the cause of the bigger problem. Sounds ominous. I wouldn't call it small, though. > the technical details are below Mostly irrelevant. Here's your prize for reaching this far: https://forum.mxlinux.org/
