I've only had two audio issues.
Maybe about twice a week, one type of sound will cut out completely until reboot - battle noises, BGM, etc. A reboot fixes it.
Second, in the Old Sharlayan BGM, there's an INCREDIBLY loud clicking sound every 30 seconds or so, that with my headphones, sounds like it's coming from 3 feet behind my desk chair.
The clicking sound stopped with the update; and I haven't lost sound ... yet.
