Blackshark V2 Pro (Not 2023) Equalizer Not Applying

I’ve had my Blackshark V2 Pros for at least two years now but all of a sudden my equalizer on Synapse 3 has stopped working. I’m on Windows 10.

It’s odd because I was tweaking it literally just the other day and changing the equalizer settings has 0 effect on the sound quality now. I can still change the volume of the headset from Synapse which is responsive but changing the sliders for the equalizer doesn’t work, changing the bass boost doesn’t work, THX audio doesn’t work (I don’t use this feature anyways), sound normalization doesn’t work, and voice clarity doesn’t work. The buttons and sliders are all useable but they don’t change the sound quality.

I’ve looked through the forums and have seen many Windows 11 fixes with changing “Audio Enhancements” settings but doing the same on Windows 10 hasn’t really worked for me in the advanced properties of the headset. I’ve clean installed Synapse multiple times. I’ve used the driver cleanup tool which, thankfully removed  many unused drivers over the years I suppose, but did not change the outcome. Not really sure what to do now because all the forums I look at are quite repetitive. I also cleaned out the registry. Any help? I’ve become awfully used to my equalizer settings and this is pretty irritating.
