Windows 10 64 2.42 external DAC WASAPI Loopback no recording signal

Hi All,

New user here with a new DAC> Topping D50s.

I’ve got everything set up and v2.42 see’s the DAC with loopback enabled as pictured but when I record 44.1 digital, the cursor moves but no input audio/waveform appears. I’ve exported samples and played back with no audible signal.

So, I can play the source material through the DAC and hear it.
I can see the DAC in 2.42 but cannot get an waveform to appear or export/playback.

Anything obvious I’m missing here?

Thanks in advance for any insight you can share.

Kind regards,
