Under audio settings I have ....CPU ARMv8+ NEON64 64bit underneath VEC...NEON64 so looks like the correct download for device.I am happy that it works then.
I don't have that enabled, but it needs it when playing through a dap and not just external dac i guess. Thanks for the information, it might be helpful for me in future and if someone reads and want try this.
The one in the Fiio is something like 32bit+DSD64 in Neutron. One side to make sure you do not get distortion in sound and another to save battery i think. And....this is the reason why people often do not hear difference with all to dsd option On in their daps.
Ahm....how is the battery consumption ? Is it OK ? I have phone that i use as music player and i have 7-8% per hour 32bit+DSD64. 10% with 64bit+DSD64. Around 11% with 32bit+DSD128. And 15% with 64bit+DSD128. Multithreaded processing will add 1 or 2% + to all these. So...if it can without it, its better to turn it off. Also for comparison with 'follow source frequency' i get 3-4% drain per hour. Not that for your dap will be the same numbers, but just to give idea. 64bit+DSD64 is best balance, quality and performance i feel.
Something else that may help as information to someone that reads. When you go to settings audio, at the top is written what type CPU a device have. And in brackets is written 32 or 64 bit + Neon for example. Then under it in VEC you might have 'Neon' or '-' nothing written. If it's nothing written then probably the google play store have not installed the best possible version of Neutron so one might want to check Neutron website for manual downloads and installation. That counts only for 32bit CPUs however as i understand. If the device have 64bit CPU and Neutron works, then this is the optimal one as 64bit version does not have versions with or without Neon. What this does is you get 20% or something around those lines more performance with VEC 'Neon' vs '-'. So...if for example you get distortion and your device can't do upsampling to DSD well, installing the correct version might help a lot. Will not do miracles but can help.
Happy listening.
PS: and something else, whoever reads. It also depends on what sample rate the input file has. So...Flac 16bit 44 100hz will be easier to upsample to DSD than Flac 24bit 96 000hz and so on. This is another reason why one may get distortion with hi-res files vs standart 16/44. Keep this in mind also. Its not huge difference, but there is.
With regards to battery life it looks similar to yours around 10% with audiophile on , 64bit + DSD 64. Not a problem for me I’m mostly listening at home and usually only a couple of hours at a time .
