Little late to respond but wanted to leave this here in case anyone else is having this problem and couldn't find a solution.
The above solution using Equalizer APO works perfectly! Initially it had no effect but after changing the install to SFX/MFX in the config and restarting I was able to get it working. I cleared out all the settings but the preamp in the editor. I set it to -20db which is the max it would allow, that helped a little but it also lets you add another preamp and do the exact same thing to make it even quieter, so right now im running at -30db which lets me put the volume up comfortably to the 30-50 range which gives me a lot more flexibility with volumes.
Thanks for the recommendation!
