Hello, recently I manually configured some developer options since my USB Dac was not recongnizaed by my S10e phone. In the devoloper options, I choose in USB predetermined setup, the option that said MIDI. Magically I started to hear music through the DAC. I was curious so I tried different apps and different sample rates tracks and I was surprised. Every time I played something 32-48 khz, my DAC turn on the blue light. I also tried Hi Res audio and the light turned green. I'm concern because I cannot know the exact sample rate, I can only know if it's CD or HiRes. Has someone tried this with a DAC like the topping D10 that shows on a screen the sample rate?. This could be a game changer for android users.
