Unfortunately I don't that option if any of my active devices...

In fact, it works. I am on a MI 9TPro, but seems don't fully decode in full and its only working on 48kHz.

Thank you. And how about the Amazon Music Unlimited?

@FiiO Kang any new or update? Saw that are also some similar complaints with Tidal, and even the system recognition.

Amazon Unlimited V24.5.0 Xiaomi Ultra - Android 14

@FiiO Kang , I think you are using a different version of the app, with lower definition. Even with the yellow light on, and all working on the Fiio control, there's no sound, no output.

Amazon Music (Unlimited)? Hires?UltraHD?

Thank you. Let me know the results then from your side, this is quite annoying.

Dear @FiiO , So, after a new burning, all good and running the 0.08 version: - Blackplayer, Spotify, Fiio Player all working. - Amazon Music does not work, it seems an issue on how KA11 decodes the signal. I have a small ESS Asus dongle and it works, so its really something on the signal...

Dear @FiiO , thank you for the answer. UAC 2.0 is selected by default, and so far this is happening with the streams coming from the Amazon Music App. KA11 seems to detect the signal and it works for a few milliseconds and then becomes mute. When mute all continues working, the app stream and...

All updated, but the Amazon issue continues. @FiiO any idea or solution for this?

I received mine today, but just find out that doesn't work in Amazon Music. Its detects the >48KHz once the light changes to yellow, but there's no sound. Spotify (<48KHz - Blue) is working properly. @FiiO , Should I update the firmware to the 0.08?

Its kind a surprise Fiio still stick to the 660 SoC, but I still wait and I am expecting to see this with Android 12 (at least). But using the 660 will also narrow the chances of upgrade the system to more newer Android versions in a very short time frame.

Where did you get the Android 10 reference? There is and article that points to Android 12, even still on the 660 SoC.

Seems that it will compete side-by-side with other interesting device...
