Loading first track... and nothing happens

Hi, I have just installed Audirvana for the first time. I have local files and Tidal linked, and it displays everything fine. When playing Audirvana through the built-in speaker of my Imac, all is well. When I then select my Audiolab 6000N as the output, it says “loading first track…” and nothing happens from there on. Any idea? Thanks!

Hello @mvdh,

Can you check the firewall settings: In System Preferences > Security and Privacy > Firewall > Firewall Options > Automatically allow signed software to receive incoming connections check that this setting is selected and “Block all incoming connections” is not selected.

Hi, I did and they were all as you indicated. Mysteriously though, it now works - no idea what happened…
