Hi,

I had a similar problem with my Primare DAC 30 ([ROCK losing USB DAC](https://community.roonlabs.com/t/rock-losing-usb-dac/123421)). Unfortunately, I didn’t receive any assistance from the Roon support team 😒 Primare didn’t answer my mail either ☹

Fortunately, I was able to solve it myself but I can’t post my solution because my ticket was closed automatically although still unsolved. Therefore , I thought I’d inform you what I did in order for you to try yourself. Check your audio settings In the BIOS. I had to make the following changes:

1. USB Legacy = deactivated (was activated)
2. XHCI Mode = deactivated (was activated). Google this one! USB 2.0 ist definitely what you want for audio!
