[USB-Audio - Logitech G933 Gaming Wireless H, playback] volume controls wrong output

[CuTeBoi]

I have multiple outputs:

I have a Dell AC511 USB Soundbar which has its own volume control
I have a G15 Logitech Keyboard with volume control
I have a G933 Wireless USB Gaming headset with a volume control

Currently I have my default output for the whole system is the Dell AC511 USB Soundbar.
Chrome has configured communication device as the G933 headset, NOT the "Default" sound.

I am unable to control the volume independently of the headset or the system with the correct volume controls.

I change volume on my G933 Headset, and the volume of the system is being controlled, and the volume does not change on the headset.

I change the volume of the G15 and the Dell AC511, and they correctly control the system volume.

This was not an issue on 16.04, each volume control would control its output correctly, while the G15 always controlled the System Volume, never the headset.
