Hello - I started experiencing this issue directly after the last FFXIV patch and have not been able to play for more than 10 minutes since then. It's possible there were Windows 10 updates around that time frame as well, but unsure, as I have them auto updating. As far as audio set up, I utilize the Razer Leviathan soundbar, which has its own digital devices (but worth mentioning nothing has changed with that configuration and I have never had an issue previously and still do not with any other game or application).

Not sure what approach to take in regards to troubleshooting this issue, as it just appeared to happen overnight with the latest patch. From what I've seen, I don't think it's actually an audio issue, rather a more critical conflict issue that is causing issues with core processes in the OS and crashing audio, other applications, etc. My first thought is that it's something that was tied to DX11 that possibly changed and is now causing conflicting breaking changes.

I've seen others on the forum talking about similar issues since the last patch, so curious if they're related and what the common configuration may be.
