Browser Source audio and video not synced

Hello,
I'm helping run a tournament that is rebroadcasting 8 Twitch streams through OBS and letting OBS control the audio as well.
The broadcast PC is getting roughly ~250ms of audio delay on each browser source, but not having any other issues.
However, when I load 8 browser sources on my own PC, I don't get any noticeable delay.
The broadcast PC has much better specs than mine does, so what could be the issue?

What troubleshooting steps can we do here to try and fix this problem?
Currently we are just adding a 250ms render delay to the browser sources.
However, the delay is not consistent, so it doesn't always fix the issue.

We're both running OBS version: 25.0.8

Broadcaster specs:
Code:
CPU: Intel Core i9 9900K
GPU: NVIDIA GeForce GTX 1080 Ti EVGA Hybrid FTW3 Edition
RAM: 32GB DDR4 Trident Z Royal
OS: Windows 10
Audio interface: Objective2+ODAC Combo
Internet speed: Gigabit

My specs:
Code:
CPU: Ryzen 5 2600
GPU: 1070 TI
RAM: 16GB DDR4
OS: Windows 10
Audio interface: Focusrite Scarlette 2i2 1st gen
Internet speed: ~10 Mb/s on a good day

Hi Megalon! This might be a late reply but i had a similar problem that i ended up fixing.
So i'm just gonna reply here in case other people find this thread while looking.

When you add a browser source, you have the option to "Control audio via OBS". Disabling this and setting the volume in the browser sources themselves instead fixed the audi desync for me.
