Audirvana can talk to Diretta via the UPnP protocol. By all reports, it works quite well. If you have Audirvana, you don't need Qobuz Connect as Audirvana handles the communications with Qobuz servers and streams the audio over your home network to your endpoint(s).
AudioLinux (and, by extension, my preferred Diretta implementation), is not compatible with the Qobuz Connect app, but Quboz works just fine when streamed from a compatible media server, like Audirvana, Roon, etc.
