My experience may be a unique one with a combination of software and hardware.
When I open Telegram (1.9.3 from the repo - but also many previous versions) on Solus Budgie, my USB Blue Yeti Nano microphone starts flashing yellow, and goes back to solid red or green when I open Sound Settings (which I have permanently on my panel).
It's one of these things I have just gotten used to, but also wondering if anyone here is experiencing the same or has any idea what is happening to cause this?

For the record, this situation is no longer happening.
When I open Telegram my USB Blue Yeti Nano stays either red or green, and does not go to flashing yellow.
Unsure if it was a Telegram or Solus update which fixed the issue, but I am happy!
