I don't understand which method I have to use for removing audio HISS on analog output.
I have to set disable_audio_dither=1 as stated here
https://www.raspberrypi.org/documentati ... t/audio.md
or audio_pwm_mode=2 from here?
I have a RPi 3 and my system is updated with kernel 4.9.35-v7+, the latest official kernel from Raspbian.
