When you switch from Speakers to Headphones, onboard-audio and expansion card audio that is correctly setup, re-routes the pins (in a technical sense, not an electrical sense.) So for some sound cards this is treated as ejecting the sound device as it's switching from "front speaker" to "headphones" which goes through it's own op-amps. Yes "lower sound quality" is a nonsense reason for not simply going "oh the audio device has disappeared, better mute until it comes back" rather than crash the game. I know what he's trying to say and I just don't believe he knows it's crashing because he personally plays it on the PS4. The tech forum is filled with two kinds of errors right now.
Stack traces which are the "USB/HDMI or Bluetooth headphones unplugged" crash, and "DirectX error" 1100000f or 11000002 are all on an uptick over the last patch cycle.
These kinds of crashes are things that SQ and mitigate in some way without degrading anything, if it's a watchdog thread that checks for "hardware unplugged" messages and knows to react to them, or at worst, temporarily mute the audio/video until there is a valid output device, or they could have it fail more gracefully with a "Oops your sound card has gone away, click here to reconnect (device name)"
And FFXV is notoriously buggy in the nvidia gameworks libraries, that the recommended way to play the game is to turn all the nvidia features off due to memory leaks. Same game engine family as FFXIV. FFXIV is actually the better working of the two on the PC.
Edda first appears outside Sastasha before you play it the first time. At that point she is little more than a player model with a few lines that you don't even need to interact with. The Edda that appears in PotD is a specific boss model that isn't the same as the first incarnation.
The issue with Zenos is simply that he's the bad guy and his design was created with unique features that the player models don't have. More or less, we can't get "zeno's hair" any more than we can transform into a dragon a la Nidhogg-Estinien .
The developers have to specifically make something. And really the problem is that long hair clips normal models. All my characters have long hair in some form and the only ones I can really stand are the pig-tail/pony-tail designs that don't clip into the back.
