BOSS 1.2 & VOLT : low buzzing

[AnnaBlume]

Hello,

In my combination of RPI 3B+, BOSS v1.2 & VOLT a low buzzing can be heard. I use the certified RPI power supply for both RPI and BOSS, and a 19V /65W notebook PSU from HP.

The buzzing doesn´t increase when volume is iscreased. Has anybody discovered this as well? Any clue where it comes from?

Cheers, AnnaBlume

Usually that means your PSU is very noisy (19V), I would try to change it

Thank you, I´ll change PSU (what will take some time) and revert back.
