iMac volume is very low after Proton Meet call
My iMac (Retina 5K, 27-inch, Late 2015) has Monterey version 12.7.6 Last night I was speaking to someone on Proton Meet (they sent the link). Since then my iMac volume is very low. I created a guest user account and checked the volume there and it is fine so it's not the sound card. I checked the sound in the settings app and even when it's on high it still sounds low. What can I do to reset the sound card settings for my login?
Thanks for your help.
