I’m experiencing a persistent issue with the new USB-C lossless audio feature on AirPods Max (firmware 7E101). I’m using original Apple USB-C to USB-C cable and have tested this setup across multiple Apple devices, including: • iPhone (running iOS 18.5 beta) • iPad Pro with USB-C • MacBook Pro (15.5 Beta) ❗️Problem: Despite Apple’s announcement that AirPods Max now support wired lossless audio over USB-C, I’m unable to get any audio output via USB-C on any device. • On iPhone: I disabled Bluetooth, connected via USB-C — no sound. • On MacBook: The device is shown as “AirPods Max USB Audio” in System Information > USB, but it does not appear in Sound settings or Audio MIDI Setup as an available output. • On iPad Pro: Same behavior — no audio output. Other details: • I performed a factory reset of the headphones, but the LED flashes red instead of the expected amber → white sequence. (Apple’s documentation does not mention red flash behavior during reset — might indicate an error state.) • The issue is not isolated to the iOS 18.5 beta — since the same behavior occurs on macOS and iPadOS. What works: • Bluetooth audio still works fine. • The cable and USB-C ports function with other audio devices. ⸻ Summary: It looks like: • USB audio is being detected on a hardware level (at least on Mac), • but software support for output (especially on macOS/iPadOS) is either not implemented, disabled, or bugged — possibly connected to iOS 18.5 beta or broader OS-level limitations.
