Soundcloud and all other services works fine. But when I trying to listen my local media library (.WAV format) I get this error "network connection speed insufficient to maintain playback buffer".
macOS Mojave 10.14.5
2x Play 1 in Stereopair.

That being said, generally the "network speed" error is a reflection of an issue internal to your LAN, most often caused by local interference of some sort. Essentially, your speakers are having a hard time staying connected to the source of the music, i.e. your local media library. Could potentially be the hard drive sleeping, depending on where your local library is stored. Not being a Sonos employee, I don't have access to your diagnostic.
