Output to airplay only from Audirvana

Is it possible to stream content from Audirvana only to Airplay device, but leave system sounds to system device?

Don’t think that’s possible since Airplay output is selected on system level.

i can route system sounds to Airplay and Audirvana stream to local speakers, but not the opposite

Maybe your endpoint also supports UPnP.

Can you explain me how use airplay with a PC to get SONOS Players?
