UR 242 HelpPlease

i,

I purchased the UR242 a year ago, and never managed to make it work as required

My use case is that I have a number of old 1/4" tapes with some tracks on that I need to digitise.

My setup is as follows:

Akai 400D reel to reel tape player connected to
UR242 inputs 3/4 via phono to jack leads connected to
Windows 10 Microsoft Surface Studio PC via USB
Audacity software for recording

I have used a similar setup with a USB turntable for years without issue

I can hear the tape content via headphones on the tape player and through the UR242 headphone socket

I can see the monitor bars on the UR 242 software display.

But. I cannot hear or record anything through the PC.

I have tried every combination of the sound devices via the control panel, but no joy.

I have been at this for days now and I am at my wits end/

Hep please.
