I've waited for the 6.05 patch to fix the audio issues (or at least officially acknowledge them).

My sound always has been fine pre-Endwalker but then I got audio stuttering when doing
combat, inn rooms, Fates, dungeons (while in combat), Rhalg'r Reach, Raids and the Alliance Raids(the Nier raids are especially bad but I didn't encounter a sound issue in the Crystal Tower raids).

The sound seems to stutter more in cramped areas while in combat but that goes away if I position my camera facing my character.

I tried the fixes brought foward in this tread, except installing the audio pack, but the only change that had a positive effect was enabling DirectX9.
Now the stuttering only happens combat in cramped spaces, Raids and the Alliance raids although the only Trials I've done since then are some ARR Extremes so I don't know how affected they are overall.
