Audio gets interrupted while hard drive spins up

[gizmer]

If while playing audio in Windows 10 VM a disk drive is spinning up, audio gets interrupted and continues to play after the disk ist fully spinned up (couple of seconds).

I'm using an external USB sound card plugged into a USB controller passed through to Windows VM.

Using Unraid 6.5.2. Data drives and parity drives are plugged into a PCI-E SATA HBA (Host-Bus-Adapter). Windows VM uses 4 isolated CPU cores.

 

Your comments and suggestion are highly appreciated.
