I get 44.1 kHz recognized on my DAC (Topping e30) when streaming via Airplay2. From the Apple Support forum:
AirPlay 2 currently supports streaming audio wirelessly at 16-bit/44.1 kHz in the ALAC (Apple Lossless Audio Codec). Many songs downloaded through Apple Music are downloaded at 16-bit/44.1 kHz ALAC, but AirPlay 2 technically isn’t lossless streaming by definition of lossless, although it will be higher quality than AAC 256 kbps (the High Quality setting in Apple Music).
AirPlay 2 does not support 24-bit/44.1 kHz ALAC or anything higher than 44.1 kHz. It’s possible, but uncertain, that Apple could add support for this in a future update to AirPlay.
