Solving interference when using Audio Hijack

A simple three block diagram from Audio Hijack - the first block ("Application, Discord") connects in parallel to ("Recorder, MP3 Stereo, 256kbs", with 'pause' and 'split' buttons) and also to ("Output Device, Jabra SPEAK 510 USB").

If you've been following my posts on the Jägermeister Adventure, you'll know that I've been recording the audio from the game sessions to process and capture the transcript. 

I'm using a MacBook Pro M1, with a Jabra Speak 510 USB conference speaker attached to it. I capture audio with Audio Hijack (by Rogue Amoeba).

I'm seeing an issue when recorded where the players are getting interference from my channel when we're recording. The diagram above shows how I have Audio Hijack's blocks set up. I think that the issue may be that Discord is repeating my audio input a fraction of a second after I talk and it's interfering with for the other players. However, I'm not sure how to solve it.

I tried a serial connection instead, but the issue remains.

I then tried switching off the output block, which removed the interference  but that meant I couldn't hear the other players (but they could hear me).

Using Chrome (with Roll20's own AV) as the audio source also makes no difference.

I'm wondering if the answer may be a headset? Anyone got any ideas?

Thanks!
