kwatch Posted March 28, 2023 Share Posted March 28, 2023 I have a Holo Audio Spring 3 KTE connected to my MacBook Pro via USB cable. When I attempt to play high-resolution lossless audio files in Apple Music, the Holo Audio Spring 3 KTE display shows that the audio is playing at 44.1K, which is not the expected sample rate for high-resolution files. However, when I use Audirvana to play high-resolution files, I do not encounter any issues. I am wondering what could be causing this problem. Link to comment
Axiom05 Posted March 30, 2023 Share Posted March 30, 2023 That's because Audirvana handles sample rate changes for you, I believe this still needs to be done manually if you're playing using Apple's own app. kwatch 1 Main System: [Synology DS216, Rpi-4b LMS (pCP)], Holo Audio Red, Ayre QX-5 Twenty, Ayre KX-5 Twenty, Ayre VX-5 Twenty, Revel Ultima Studio2, Iconoclast speaker cables & interconnects, RealTraps acoustic treatments Living Room: Sonore ultraRendu, Ayre QB-9DSD, Simaudio MOON 340iX, B&W 802 Diamond Link to comment
stefano_mbp Posted March 30, 2023 Share Posted March 30, 2023 @kwatch the only way to avoid this problem is to use an iphone/ipad to play Apple Music, connect it to the dac using the CCK (Apple Camera Connection Kit) accessory Stefano My audio system Link to comment

kwatch Posted April 2, 2023 Author Share Posted April 2, 2023 I purchased the Apple Lightning to USB3 Camera Adapter and tested it on my iPhone 12 and iPad (9.7", 2017) models. I have set Apple Music to play in Hi-Res Lossless quality, but the music is only playing at 44.1 kHz instead of the expected higher quality. What could be wrong? Did I miss anything? Link to comment
kwatch Posted April 2, 2023 Author Share Posted April 2, 2023 It probably allowed for auto audio sample rate switching before, but it seems like the sample rate is now locked at 44.1k Link to comment
kwatch Posted April 2, 2023 Author Share Posted April 2, 2023 I think my iPad(9.7", 2017) is not compatible with Hi-Res audio. Link to comment
kwatch Posted April 2, 2023 Author Share Posted April 2, 2023 i asked ChatGPT if all iPads are compatible with Hi-Res Lossless using the Apple Lightning USB 3 Camera Adapter. It replied as follows. No, not all iPad models are compatible with hi-res lossless audio when connected to an external DAC via the Apple Lightning to USB 3 Camera Adapter. The following iPad models are compatible with hi-res lossless audio when used with the Apple Lightning to USB 3 Camera Adapter: iPad Pro 12.9-inch (3rd generation and later) iPad Pro 11-inch (1st generation and later) iPad Air (4th generation) iPad (8th generation) It's important to note that the external DAC being used also needs to be compatible with the iPad model and the Lightning to USB 3 Camera Adapter for hi-res lossless audio to work. It's best to check the specifications and compatibility of both the iPad model and the DAC before making a purchase. Link to comment
