Hardware: Pi zero
Afternoon - I have set up Volumio (running in a a Bush DAC90) - it works but there is a background hiss on radio stations?
Any ideas would be great, its like listening to FM with a slightly weak signal,
edit update - at low volumes there is a constraint hiss when playing, none when not playing. Over volume 55 its not as noticeable but when listening at low volume there is a notable background hiss…
