Dacmagic plus outputs only high pitch noise

[TheMacap]

Hello everyone,

 

I've been using dacmagic plus for about 4 years, however I bought it used so I don't know how old is it. Since last 3-4 weeks it does'nt work properly. When I turn it on and when there is a input signal, it only produces a noise. When it happened for the first time I let it on for 15 minutes and selected an empty input, then I selected my usb input again and turned it off and on. It started to work properly. But when I turn it off again it made the same thing. Now waiting 15 minutes or even longer such as 24 hours doesn't work, it only produces high pitch noise.  I tried different inputs as well, usb-PC, optical-PS4, Bluetooth-Phone but the result was same.

 

So I think some caps went off but I have no idea. If it is something like that I can solder new caps but I don't know how should I tackle this problem. It would be great if someone could help? Thanks in advance.

 

Here is a video of what happens:
