I have the latest Zoom so that's not the issue. When I joined a meeting half an hour ago, sound was fine. I need to do a study and after a couple of minutes with me being recorded, the sound suddenly went very low. I could still hear the host, but my speech wouldn't raise allowing me to give the feedback sought. I have rescheduled so I have a few days to figure this out. I know this was an issue last time I used zoom, I just don't know how it was able to be fixed. Please if someone uses Zoom more frequently then once around the sun, help. Thanks. If you know of others not on here, feel free to have them get my contact info and talk to me. Thanks. A very pissed Irishman P.s. Even after I left the meeting, my sound was low until I used the keyboard to raise the volume so it might be a system sound issue. note I was not wearing headphones at all.
