Hey there fellow forum members.
I am having issues using audio in a Windows 10 guest VM. I passed through a USB port for my Audient Evo 4 DAC. The problem is the audio distorts or cuts out for a second from time to time out of nowhere but also when the system is under load. For example when opening Firefox or another application distorts it. I haven't figured out a way to get rid of this issue. Passing through the whole USB controller does not make a difference so I am looking for another solution. Has anyone dealt with this issue? I am not sure the MessageSignalInterrupt solution that is often suggested is useful in my case since it is not PCI. I would appreciate any help :)

Cheers

My system:
Xeon E-2124G
Supermicro X11SCA-F
2666Mhz DDR4 UDIMM ECC
Nvidia GTX 970
Intel X520-DA2
Intel i350-T2 v2
2x500GB Crucial MX500
2x500GB SanDisk SSD Plus
