My music setup at my house is no longer functioning well in Catalina. The iTunes Remote app on my iOS devices no longer functions to control the new Music app. And I think my Gen 1 Airport Express devices aren’t functioning the same.
I don’t believe there is a replacement for the iTunes Remote app.
Does anyone know of an inexpensive Airplay 2 device that I could use in place of my Airport Express that would allow me to stream from the Music app to a pair of powered speakers?
I don’t think there are any 3rd-party devices that do that. Gen 1 Airport Express cannot do Airplay 2, but you can easily buy Gen 2 models on eBay for $20-$80.
I have powered Presonus monitors attached to an Airport Express (I’m not on Catalina yet). Idon’t cast from iTunes/iOS but I do regularly cast from iTunes/Mac and from Apple Music (iTunes on Mac, Music app on iOS) to the speakers without any problems. (Not to mention a variety of streaming music apps on iOS, or audio casted on the Mac via AirFoil.)
That said, the era of using those monitors is coming to a close. I simply adore my HomePods, and I may pick up a 3rd one if someone comes up with a good enough Black Friday deal. (B&H has them for $275 right now, but a couple of weeks ago BestBuy briefly had a clearance sale at $200)
