So the first test is requires HiBy's USB to SPDIF cable, did you use it?Here is the verification music file, it is a repackaged DSD in a Flac container. https://github.com/Lurker00/DX200-f...README.md#tracks-to-test-bit-perfect-playback
If the player or DAC does not know how to bit perfect, then there will be no music to be heard.
The instruction says
The point is possible downsampling to 44.1kHz in Android system, and not mystical bit changing in HiBy OS.Connect your device' S/PDIF output to S/PDIF input of a DTS-capable decoder, and start playing the track in any software player.
Anyway, dts_test44.zip plays correct and I can hear music. The third file DSD64-in-DoP.flac is also plays correct and I can hear music.
I use FoxLess DA1 DAC and it shows correct (not changed) sample rate for PCM and DSD rate with LED color indication.
Moreover I tried the different test files from 2L and it's always shows correct LED color indicator.
You can also dig deeper and get access to UART log console, HiBy OS is always reports sample rate to log.
BTW SPDIF and USB are different and separated 'sound cards' (or output devices) in HiBy OS. Specifically spdif can be limited to 192k sample rate and USB output is unlimited.
BT output is also limited to 192kHz.
