My profile photo is of my desk during covid (yes my profile name and photo are just whatever happened to be in front of me at the time).
A pile of CDs, a cuddly toy, a deodorant can in the background and a speaker plugged into a CD/DVD player that gets louder as the volume number decreases all...
Slightly alarming though when the call that I've barely been listening to goes silent for a few seconds and then somebody says "you're on mute by the way".
No way to work out who they're waiting to say something, so just have to sit tight until either a) somebody else works out how to unmute...
