OBS - Macbook Pro - Game Audio Quality is Terrible

[bedoyabean]

My stream's game audio quality output is trash

Here is a link to a sample stream output I just tested. My mic quality is fine but the game audio is absolutely terrible. Generally what I see happening is while I'm streaming, I can only hear other voices, including in-game voices on stream. But not any sound effects like gunshots or in-game music. And if I can hear it, it's super low or sounds crappy like in the link I sent

I've been scouring the internet but can't find a solution so I wanted to come here for help

Here is my hardware setup:
- Macbook Pro M2 2022
- USB Hub: PLUGABLE USB-C TRIPLE MONITOR DOCKING STATION, 60W LAPTOP CHARGING
- Elgato HD 60x
- Xbox Series X

Here is my software setup (included in screenshots):
- OBS V 30.0.0
- Streaming via Restream.io
- 5,900 Kbps Bitrate output
- Mic/Auxillary Audio 1 is my external mic (FiFine USB mic)
- Mic/Auxillary Audio 2 is my Game Capture HD 60x (Elgato capture card)
- Sample rate at 48 kHz
- Log file from OBS

Observations:
- I see the volume going up for the 'game audio' from the capture card while on OBS whenever there is in-game sound. So I know it picks it up and I slightly hear it on stream, but the quality is atrocious

Attempted Solutions:
- Attempted to use Shinywhitebox but the software didn't seem to run on my Mac version (Sonoma)

I can't figure this out. If anyone out there has any ideas, this would be incredibly helpful! (New streamer here trying to work out the kinks)

Edit, here is my updated OBS log file. I tested a game of Fortnite -> Went into the pre game lobby, shot some guns and there seems to be an echo + lack of game audio sound coming out
