No Audio on Several Devices

Hello, I am hoping to be a convert from Stremio to Nuvio, however, after configuring with Torbox via Comet and AIOMetadata, I am not getting any audio on any device I try and use it on. My Windows PC via the web player, a MacBook, an Android phone and my Google Streamer 4K. Can anyone assist? I've tried searching through the settings but most of the settings people tell me to check I just cannot locate for the life of me.

TIA
