I believe it is coincidence if your sound quality changed by selecting a different driver. Latency, maybe; quality, no. But whatever works...

In your original post, you asked about shutting down other tasks. If DPC Latency Checker shows no problems with underlying services, I have to ask, what are these tasks to which you refer? If it is other programs running while BIAB is running, then yes, close them. If it is something else, please elaborate.
