Hi,
I have problem with rampage 5 , aftr doing hibernate i hear a whistle and or "pop" & constant dc voltage on headphone output.
It happens on every hibernate. But this time i forgot to unplug before turning off.

Already my PA first input stage amplifier ruined thanks to constant dc.

I would suspect the headphone resistance testing circuit or bios version but ..
What could it be caused from that at hibernate or poweroff it whistle or put dc voltage on audio output?
