People might have dismissed this post of yours thanks to all other ramblings you love to do in this thread, but surprisingly this had a
DRASTIC IMPROVEMENT for me. I have finished Stormblood and its patch content today and had
NO STUTTERING/VO CUTTING OUT during all of the cutscenes. The problems stills comes up in combat but I can deal with that. It's barely noticeable for me atm. Before overclocking my CPU, 85% of the dialog cutscenes had been HORRIBLE. Constant stuttering and audio popping, with acted out lines being slowed down to a point of cutting out halfway through text. Sometimes it would be a constant ear rape and nothing more - it was THAT bad. I have no idea how I was able finish ARR, with addition of full HW, and most of SB. Surly, that has reduced my potential enjoyment of these storylines but that's in the past now. Now I'm ready to have fun with Shadowbringers as that's the one expansion everyone praises over all. Can't wait!
For people still confused on what to do - I suggest you watch this short video as it explains what to do rather well:

CPU I own is
AMD FX 8120. For it I've tried few different set ups but the one that seems the most stable is 4,1 GHz. I'm confident I could go higher but I really didn't wanna increase voltage control in BIOS as I use a dogshit stock cooler. I had troubles with overheating in the past. I'd also recommend changing your power plan to
BALANCED (Control Panel > System and Security > Power Options) if you also have a shite cooling in your machine. It might feel redundant but I swear it helped me achieve peace regarding the sound issue.
Apologies for a chaotic comment but I'm tired AF, been up the whole day. Once again thank you Xenophine, and I hope others might find this useful. Good luck!
