I was writing a similar post before realizing I was in the client beta forum by mistake and then I posted it by mistake. While waiting for mods to remove that, I'll post my related audio issues here to corroborate other audio related issues.

With record microphone on and record audio from being set to all system audio, my voice is barely audible. With automatic gain control enabled, my voice is audible but very distorted/crunchy/loud. I believe that this could be mitigated if the user was allowed to control the volume of their non microphone audio and/or if automatic gain control had a limiter put on it to prevent clipping.
