Fallout 4 no audio on deck

So i installed fallout 4 on the deck the other day and i was surprised it worked flawlessly... at first.

I use my deck away from wifi a lot so i got about 2hrs into a new save with zero issues. When i got home i decided to plug the deck into the dock and try to play fallout on the tv.

The game launched, but did not upscale to the tv and was still in 720p. So i re launched the game, tried to change my resolution in the game launcher but max res was 720p.

I dicked around with the dock in desktop mode trying to get it to upscale correctly but ended up reverting back to what i had video setting wise.

I disconnected the deck from the dock and tried to launch fo4 in game mode again, and the game refused to launch.... so i flipped back to desktop and the game launched and ran fine with audio.

Went back to game mode and the game launches again but absulutly ZERO audio, not even the menu screen. Every other games audio works fine.

I uninstalled the game, nuked every fallout config file i could find, and reinstalled... nothing. Tried -autoconfig as a launch paramiter.. nothing

Forced compatability mode makes the game not launch. I have a hunch that when i launched the game on the dock some audio setting got swapped to the tv settings and now its not going back, but fallout lacks any audio device settings.

Sorry for the wall of text but i'm stumped and i want to play this damn game for my 5hrs of travel a day to/from work.
