An AirPlay 2 licensee reports that Apple Music sends an AAC stream to their devices when playing back Apple Music Lossless tracks, despite device support for ALAC.They do say that HomePods, which are AirPlay 2 receivers, only support AAC playback at this time. Apple doesn’t say anything about AirPlay on their Apple Music Lossless support page (as of ).
The situation on iOS is unclear at this point. What is true:Īpple Music on MacOS does not transfer lossless data over to AirPlay 2 receivers when playing Apple Music lossless tracks. People assumed that they’d be able to play back these lossless streams losslessly over AirPlay because AirPlay uses lossless ALAC (Apple Lossless Audio Codec) to transport audio.

However, when the output is an AirPlay v1 receiver, the iOS version apparently maintains a lossless chain from Apple’s servers through to the AirPlay receiver (MacOS switches to stream an AAC version from Apple’s servers and then uses ALAC to transport that over the LAN)Įarlier this month Apple released an update to Apple Music that allows “lossless” streaming in addition to the previous high-quality AAC compressed version. It looks like AppleMusic on iOS and MacOS use AAC when the apps is set to use an AirPlay 2 receiver for output. June 25, 2021: More information that adds to the picture on iOS.
I will investigate further as time and ability permits. There is evidence that the iOS version of Apple Music behaves differently with AirPlay v1 receivers. UPDATE June 23, 2021: My testing, below, was done on MacOS.
