Strange audio on PC in Main Menu and Gameplay

When I play Halo:MCC on my laptop, I experience very a strange audio problem that is quiet difficult to describe. It sometimes sounds like the audio is very low bitrate and other times it sounds like most of the audio is missing or heavily muffled. This problem does not affect my desktop PC.
This problem occurs both in the main menu and in gameplay. I’ve noticed that the problem starts as soon as I press enter on the title screen.

I have captured a video to demonstate the problem here: - YouTube

Can anyone help shed some light on this issue? I know that there are audio issues that 343 are currently working on fixing, but I haven’t seen anyone report this kind of audio problem as of yet.
I have tried the usual troubleshooting steps of reinstalling the game, updating Windows and graphics drivers.

For those interested, here are my laptop specs:
Model: Razer Blade 15 (Advanced early 2019)
OS:Windows 10 64-bit Build 18362
CPU: Intel i7-8750H
RAM: 16GB DDR4
GPU:Nvidia RTX 2070 Max-Q
