Ah. Okay. I see what's happening. Something is triggering the volume on Tabletop Audio tracks when you play another track simultaneously. A really good example I'm playing Tabletop Audio's "Solemn Vow", which is an instrumental track rather than an ambient one. It's louder than most. If I start playing that at maximum volume, and then play a BattleBards Track like, "Tavern Owner - Epic Tavern", you can hear the volume drop on Solemn Vow noticeably. I tried doing this the other way around, and it looks like the volume is always dropped if you're playing a Tabletop Audio track alongside anything else. I'll put together a bug thread for this. Thank you for pointing this out.
