d3fmod hifi blaster

Unread post by Milspex »

Installed the hifi blaster dac in my ironclad but now I get a whining noise when the unit is powered off (at all times)

what could this be ? faulty install, faulty board, solder problem? I emailed Roberto but no reply yet. Figured someone on here could also shed some light on the issue.

Are you using HDMI output with anything like a HDMI switch ? as the HDMI on the DE10 is not isolated and can partially power up via HDMI power.
Apart from this you will have to wait for Roberto
