UPnP problems with Audirvana

Hello, I searched the site but couldn’t find an answer.

I’m using Audirvana to stream to Volumio on an RPi using UPnP. The connection is wireless. Everything worked fine until last night when I restarted the computer. Audirvana still connects to Volumio but there’s some sort of issue now. Track will load and then not work (doesn’t play and no audio output). Volumio displays a “Failed to decode Audirvana wav file” error. Any idea what’s going on?
