Topic: Fireface UCX WDM audio dropouts
I have a Fireface UCX connected to a Windows PC:
CPU: Intel Core i7-5775C
Mainboard: Gigabyte GA-H97N-WIFI
The Fireface was running stably for years on Windows 8.1, connected via Firewire using a PCIe extension card.
A few weeks ago I updated to Windows 10. My Firewire card does not seem to work correctly with it, so I switched the Fireface connection to USB (using USB driver 1.167). Since this change, I encounter random audio dropouts when I play back audio via WDM (e.g. Spotify, YouTube). Audio via ASIO seems to work correctly (at least I did not have any dropouts there, yet).
When a dropout happens, the meter of the output channel in TotalMix FX drops as well. The error counter in the Fireface USB Settings dialog does not show any errors, though.
The manual suggests using a dedicated USB controller for the Fireface and connecting all other USB devices to a different controller. I downloaded USB device tree viewer (https://www.uwe-sieber.de/usbtreeview.html) and found out that I only have one single USB controller, so I cannot change it. I tried different USB ports, but this did not make any change.
Does anyone have an idea how to solve this?
