Hello,
I own this old but trusted unit,and some time ago I realised I can hear a very high pitched contstant sound coming from all
8 outputs on the back+front headphone output.
I tried changing buffer size and various options in Hammerfall DSP settings but nothing fixed my issue,except when going from:
96khz down to 88.2,then the sound is barely audible so it doesnt ruin playback on quiet parts.
same thing with 48khz,high pitch noise just a bit lower in volume than 96khz.

Can anyone give me an idea what it could be and how to fix it?
If i need to explain anything in more detail I can,just write here or in a private message.
Thanks,
Demijan
