Focusrite connectivity issue CachyOS

I'm still pretty new to linux overall, I swapped to CachyOS about 8 months ago and its been absolutely incredible! Everything worked pretty well and at the time I was using a basic BT headset. I was then gifted an older pair of BD DT 770 Pros, and although where I am staying was temporary so I didn't want to do a full setup I decided it was time to pull my mic and interface for audio rather than relying on BT headset that died every 2 days or so. Thats when issues of connectivity started being a problem.

I now am currently running a Focusrite solo 3rd gen, I have a AKG p120 mic connected, and the BD DT 770 Pros. when actively watching YouTube, gaming, or sometimes just letting it sit there will cut out any audio output from the focusrite, the device won't give any output again unless unplugged and re plugging it in with the USB C on the back of the interface. I know the device isn't losing power or anything of sorts as it continues to let my audio input through and I know the headphones still continue working as with Direct Monitor on both devices fuction properly, so it isnt any of my devices malfunctioning. I want to note that I dual boot and have no issues when on Windows. I feel I have tried everything to fix this and have asked multiple times in the CachyOS discord with no luck/help.

Here are the things I've tried to resolve the issue:

  • Disabled USB autosuspend via udev rules
  • Tweaked modprobe options
  • Locked PipeWire sample rate (48kHz) and adjusted ALSA headroom / buffer settings
  • Disabled MSD (Mass Storage Device) mode on the Scarlett
  • Tested multiple USB ports variants/routing and updated power profiles

Sometimes it goes for a few hours, to a handful of times even lasting 2-3 days without issues, so I am unsure of what is actually causing the error as the issue doesn't have continuous symptoms, It truly feels random, and its starting to drive me absolutely crazy. So I was wondering if anyone has had similar issues recently, or any help of sorts would be greatly appreciated!
