IFW Posted February 17, 2020 Share Posted February 17, 2020 when listening to audio using the Hi-Res output on my Fiio M6 I have a faint popping/cracking noise in the background of all tracks, I've tried tweaking various settings from resampling, buffer sizes, disable the equaliser/tone control and enabling/disabling DVC. so far I've not managed to find a fix or work around. OpenSL ES output works fine but I'd prefer to use the Hi-Res output and utilise the onboard DAC (ES9018Q2C). For comparison the same audio tracks are fine when played through FIIO's default player, I'd rather use Poweramp though if possible due to the better UI, support for Album Artist tags and advanced shuffling etc....
