PC Host, Moonlight no Audio

[Muchfury]

Hello, I've been trying to get moonlight working on my Recalbox PC. I think the issue is my ignorance but I can't seem to find google solutions. I get video on my streamed to client, but no audio. I'm concerned that there is an onboard audio Piezo that is messing with the audio output. I've attempted -audio local and -audio HDMI also attempted audio = HDMI.

Feel like it's a syntax error on my part in the config but I'm pretty ignorant on how this works, any guidance would be awesome.

Attempting streaming via Nvidia Shield, not steam. Also I've adjusted "NVIDIA HDMI OUT" on my volume mixer to max.

Print out of my audio config in moonlight folder

## Enable selected input devices
## By default all available input devices should be used
## Only evdev devices /dev/input/event* are allowed
## To use a different mapping then default another mapping should be declared above the input
#input = /dev/input/event1

## Enable GFE for changing graphical game settings for optimal performance and quality
sops = true

## Play audio on host instead of streaming to client
#localaudio = false

## Select audio device to play sound on
audio = sysdefault

## Select the audio and video decoder to use
## default - autodetect
## aml - hardware video decoder for ODROID-C1/C2
## omx - hardware video decoder for Raspberry Pi
## imx - hardware video decoder for i.MX6 devices
## x11 - software decoder
## sdl - software decoder with SDL input and audio
## fake - no audio and video
#platform = default

Thanks,
