Got a PicoPSU 120W for my A1200; and after connecting everything, I noticed that the Amiga run fine, but the audio does not work as expected.

The audio output is exceedingly noisy and feel like I am playing music on a broken speaker. If I use the regular PSU, the audio is just fine using the same exact speakers.

I saw plenty of youtube videos where people modded their Amiga to use a PicoPSU, and I do not see any negative comment about the audio distorted. Do I have a broken PicoPSU? I connected the PSU to the floppy disk to get the load, then I have the +5, +12 and -12V pins connected to a square Amiga PSU connector; so nothing out of the ordinary here.
