Hi,

I bought a new DM500s Clone which arrived today from China. I flashed Commando 15 image to the box, the flash was successful and I plugged the box into the TV.

What happens is the box fully functions fine and the picture is perfect but the volume makes a glitching high pitched noise every 3 seconds, this makes viewing unwatchable.

I have tested the AV cables, tried it with a SCART and this still happens, my other DM500 work fine with these input cables. To check if the box had a issue I installed another image (Nabilosat)
and on this image the volume works fine, no issues.

I would like to know if anyone could be off assistance with this issue, I know I could just run the box on another Image but I find Commando is the best image I've found by far.
