Anyone else experience random occurrence of audible noise/hiss with the topping D30 pro? It is resolved by power cycling the unit, but really annoying. I've payed with the sampling rates a bit through Windows settings and found that changing it to 24/192 seems to resolve the issue. Not a huge deal for me, but still curious if anyone else has experienced this when set to 32/384?

First thing I would try is the firmware update if you're not on 2.44 or above.

How are you connecting your player / PC to the D30 Pro, USB?

Is there a "direct mode" in the D30 Pro settings? That would help.

I'm on version 2.44 connected through USB. It's in preamp mode because I use it for volume control of my monitors.

From the website it states that UHD only goes up to 24 bit 192kHz. Perhaps that is what the player supports. Can you try another DAC just to rule out the D30 Pro?
