Thanks for reaching out to QA and doing the additional research on the Bose QC 35. At first, I thought the issue was the headphones as well because of those same forum links you posted (and many others), but the desync was still present after I switched to Sony WH-1000XM4 and Sony WH-1000X M3 headphone models. I also tried all three headphone models with the direct audio jack connection with no improvement. I also tried to turn off my Wi-Fi router and have direct ethernet connection in case that was causing issues but that also saw no improvement.
I tried all of this again right after I read your last post in this thread just in case. A few weird things happened that I had no encountered before. When I plugged the headphones in directly through the audio jack (both Sony and Bose separately), the same quest giver that I was testing the sound on stopped having lip animations altogether. Instead only body movements (including eye blinks) would happen with mouths either staying wide open or closed. Each dialogue phase would also not move on by itself sequentially unless I pressed the spacebar and move it on manually. Additionally, throughout this time since plugging in the headphones, no sound whatsoever would play in the game. When quitting the game, the game would sort of crash and a Windows pop up saying to close down the program forcefully would show up. Once the game was restarted, all sound and lip animations came back to normal (normal meaning desynchronized for me). While there was no sound playing in the game and prior to quitting the game, I tabbed out and was able to hear sound on Youtube with no problem. This complete disappearance of lip animations did not occur when swapping between Bluetooth connected headphones. I reset the quest giver each time by abandoning the mission and restarting the conversation.
I managed to grab a video of the peculiar complete lack of lip animations with no sound using my NVIDIA overlay. I also grabbed a video with the lip animations and sound present (although desynched in my opinion) from the same quest giver. Is it OK if I send the two videos in? I also have a video of the desync from a different character as well. This way someone watching the videos would be able to tell if the delay is truly being cause by something on my end versus the game, correct?
