Quick report:
Played pretty much normally last night. Did a few quests, recruited some agents and farmed some deepstalkers and dragonlings. I did clear my journal and codex (got a few quest completes notifications to previously finished quests as well,) and I did do the mount/dismount/rest routine as I got into camps. I wasn't going back to camps anymore often than I needed to in order to either heal or just get to an area quicker. I didn't futz with the audio settings either. I also quicksaved as I normally do, which is to say frequently.
I played for a little over two hours. I had new party members as well, so I put Iron Bull into my party when he was recruited last night. I bombed around with Varric/Solas/Iron Bull. For the record, I love Iron Bull as a two-handed tank in battle. Anyway, in that time, minus about 10 minutes to go pick up Vivienne (so around an hour and 45 minutes, and that was just before I called it for the night) I had one banter. It was between Varric and Iron Bull. Otherwise, mostly quiet outside of occasionally looping music.
The only instance of battle music kicking in was when I started to get a little too close to that dragon in northeastern Hinterlands. I did not get close enough to aggro her (thankfully, as I'm level 9 and would not have survived her,) but it was enough to get the music to kick in. Otherwise, no battle music, and no hints of music in Val R. later when I went to go window shop for new gear (I'm a bit broke and a bit underleveled for it at the moment.) Not even a few seconds of music before fading out either, as what happens when I exit the Chantry in Haven.
I will honestly say that while this bug/glitch is rather depressing, I am still having great fun with the game. In fact, I stumbled across a choice I didn't notice before, and got more agents this time as a result. The banter I do get is very savored and oftentimes, extremely funny. I'm looking forward to this issue getting taken care of, as I know it'll make future completions of the game that much sweeter.
