No sound with PS Audio ethernet

Hi All… I am on the trial version for Audirvana Studio Mac version 1.5.1 (10501), so don’t have any experience with this tool.

MacBook Pro with macOS 11.4.0 (Ethernet) → unmanaged Switch (Ethernet) → PS Audio DSJ

I am using the streaming from tidal mainly.

When I play any track in Audirvana nothing is being played…. Sometimes I hear some random sounds, but no music.

If I switch to USB everything plays well.

The PS Audio Ethernet connection is working as I can use Spotify connect and stream tidal from mcontrol app.

Any suggestions on how to get this working are very much appreciated.
