I have to admit, I'm worried they're ignoring that there is a sound issue, and just once again coming back to us being picky about banter. I hadn't realised I'd lost sound recently, until I went into battle and realised it was completely gone - it took a few seconds of combat to bring it back. I've noticed lots of combat soundset delays.
I've also had battle finish and then had the game immediately go into party banter . The party banter must have pushed ahead in front of the cue? At the end of the banter, I got experience points and a battle finishing comment from my Inquisitor. The banter had delayed the experience points - or at least the experience notification sign + Inquisitor comment. I was pretty surprised, as I didn't think they were correlated. Again, agreeing with all those who say it's a priority issue.
I've been trying to keep on top of the journal in my still-glitched-but-not-quite-as-glitched-as-the-other game save. It keeps the music and combat soundsets in check. When the sound stops firing, sure enough, the journal's been filled up again. I think those that said the game is keeping track of what's in a companion's codex, and then relating it to their banter could have a point: after clearing my codex, I was surprised to see that Cole's and Sera's codex logs update on the left of the screen. At that point, it had been a long time since either of them had participated in any banter. It could have been a coincidence, obviously, but it was an interesting coincidence.
I seem to be getting party banter every 30 mins if I'm lucky - if that, it's generally 40mins or longer. (Which I know is a lot in comparison for most people!) I also know they say enemies being around should block banter, but the only place where it's more frequent is the Fallow Mire. So many bloody enemies there, and yet so much banter! Like a lot of people have mentioned before, I've also had banter trigger whilst going into combat.
I haven't been getting banter at camps, too - and I've been ignoring the requisition offers, so I wonder if that's why. My dislike for the officers at camp are deep and all encompassing.
I've noticed huge sound delays too (ie. level up, get the sound ten seconds later), and codex updating delays. (I actually don't think it was this sluggish in my other glitched game save.) I think it always takes about 20 to 30s for companion approval to show up, too - I'm always worried that it hasn't worked.
