A Google search shows that this has been asked multiple times, but there's never a satisfactory answer.
I have a HiBy R6 2020 music player. One of the features is an LED on the side of the player that glows a different color depending on the sample rate being played (blue for <=48khz, green for 48<=192khz, orange for 192+khz). It's a neat feature, even if it's mostly cosmetic. Using the stock music app (HiByMusic), the LED changes color depending on the source material I'm playing.
However, when using Poweramp with the Hi-Res output enabled, that light is always a color based on the sampling rate that I set in the output preferences. So basically it's always orange, because I have it maxed out at 384khz. Even if I'm playing 16/44.1 files, that light is glowing orange. Hi if I set the output to 192khz, it'll glow green. And if I set it to 48khz, it'll glow blue.
This is both reassuring because I have confirmation that Poweramp is really pushing out a high sample rate, but also annoying because it means there's some unnecessary processing being done to the source files by the resampler. I do have the SoX resampler enabled with no dithering, but when doing an A/B comparison between Poweramp and HiByMusic, I can definitely notice a difference in quality, with HiByMusic giving me slightly better clarity and more distinct sound stage, especially with 24/196 source material. This is with the EQ completely disabled in both players (right in the output settings in the case of Poweramp) and any sound processing done at the system-level rather than the player-level.
The HiByMusic app kinda sucks, I much prefer Poweramp, which I purchased directly for this music player (not through Play Store). I use Poweramp on all my devices and my music collection is organized with that in mind. Is there a way to bypass the resampler and eliminate that extra processing to send the file directly from the decoder to the DSP? That way the LED on my player would behave as intended, and I'd have the peace of mind knowing there's no extraneous processing happening in the decoding path.
