[Requests for Hi-Res Support (please state which build of Poweramp you are using)]

1. Sony NW-A100TPS

2. Android 9.0 (firmware 1.00.06)

3. https://www.sony.co.uk/electronics/walkman/nw-a100-series/specifications#features

Also, the stock Music player app does support Hi-Res. Looking at the Audio Detection Log, I can kind of tell why it is the only one that does...

UP, this also affects the ZX-500 series. They seem to be in the same development line. They get updates together and have similar setups.

So can it be supported on Sony NW-A100 / ZX-300 / ZX-500 series? 

From a person close to Sony I've got this info

" Sony has implemented is a proprietary upscaling across the board to 192 kHz / 32-bit, this will not be reflected in the software logs of the third-party software logs as the S-Master HX™ chip performs the up-scaling before converting into analogue signals.... An implementation that is universal and fuss-free, however, does not offer Bit-Perfect. I have provided feedback to the Sony team who are now sticking to this implementation which I can understand why. "

My question is can anything be done? If so what other info can I provide to help to get support on it ?
