a petition wouldn't change a thing, the only way we could have third party players like Neutron to play files in their native bitrate/freq would be to ask the apps devs to get in touch with Fiio so they can include a driver for the X5 III's DACs. But as far as i know the AK drivers for the X5 are not even developped by Fiio but a third party (german company if i recall) company who privably licenses it to Fiio.
Not much hope for it to happen i'm afraid.
thanks, i contacted neutron developers and hiby player developers.... answer from hiby >
FiiO claims that 3rd party apps do not resample on their players, but I do not see hi-res audio outputs being enabled on players that explicitly support them, e.g. Poweramp or Neutron.
As for HiByMusic, it does not have support for hi-res audio outputs on the device itself (rather than the USB output) and the current version of HiByMusic resamples all music internally to the expected Android sample rate, regardless of what the Android system on a given device claims to do or not do.
This makes it no better or worse than any other 3rd party music player on a FiiO, because we have not seen any evidence that a FiiO is capable of bypassing sample rate conversion for any 3rd party music player.
SRC stands for Sample Rate Conversion within the HiBy music player. It allows you to e.g. set the output to a high sampling rate even when the music is at a low sampling rate.

Hi Joko,
We tried to query Fiio's firmware developers regarding direct DAC
access API but even though their Tech. Support is responsive,
developers are keeping silence, e.g. do not reply. Thus without proper
communication with them it is currently impossible to implement direct
DAC support for Fiio except the standard output which Android OS
provides. May be it will change in the future, who knows.
I advise to keep Generic Driver switched on. Also switch on 32-bit...
Ok, then it seems firmware of your device has some issues with 32-bit
floating point samples. It is known problem of some earlier firmwares.
very very Disappointing...
... is 32 bit in neutron working for someone without disorted sound?
