Message-ID: fascinating how zoom has suddenly come into regular use. especially as until this spring i'd managed 66years entirely without it. well with a half decent headset it actually works pretty well. except the headset does just a little too well at blocking out sounds in the room, which meanwhile are going through the mic and being annoying to the other folks in the meeting. i don't believe sideband is a feature on this (arctis 7) headset. so how might i mix a bit of the headset's microphone stream into the earcup streams? do i need jack? or just some mixer software? or both? specific recommendations anyone? i tried installing ubuntustudio-audio and poking around with carla but got nowhere, lt looked like i ought to be able to make connections(patches) between various device streams, i could drag from one to another, a connection prospect would show, but would always disappear when i let go. it seemed like either my setup is missing some basic prep or i need some basic tutoring. any advice or pointers? -------------- next part -------------- An HTML attachment was scrubbed...
