LG G7 Fit Hi-Fi Quad DAC DSD support (ESS ES9218P)

[Matwar]

Hi,

I know that LG G7 Fit Quad-DAC is officialy supported by USB Audio Player Pro, but I can't make it to play .dsf files with DSD Native or DoP - they are converted to 24-bit/176kHz PCM at the output.
Is it possible to play .dsf files with DSD Native or DoP? According to ESS ES9218P datasheet, this DAC supports .dsf files up to DSD256.

Please help, as I have a lot of music in DSD :(
