Recording Issues

I've been using the podcast studio for a while now, and the past two times I've tried to use it there have been issues. The recording randomly stops, one of the participants drops out of the session, I can't hear the other participants, they can't hear me, the visualiser stops working. It is completely unusable. The last studio session I attempted, everything worked fine, and as soon as I pressed record it stopped working. I never had these issues before now.
