Huawei Mate 10 ALP-L09 (non pro version) running Emui 18.104.22.1680 (Android Pie), not rooted phone. 32bit 192khz from 3.5mm audio jack works. Test conditions: Huawei Histen sound effects (Huawei's own equaliser for earphone/headphone use) is disabled Poweramp build 853 Volume steps of 2 clicks up from silent Enable direct volume control: On No DVC: On For some reason, audio on Hi-res output is quieter compared to OpenSL ES output. Weirdly on Hi-res output, setting the sample rate at 44.1khz and 176khz, the music speed is faster. On 48khz, 96khz and 192khz, music is at correct speed. Preset equalisers with higher bass and treble sound harsh. Is there a way to get Hi-res audio output to be alittle louder, especially on lower volume; or is that how Poweramp works on Huawei phones with 32bit 192khz audio?
