Can't seem to monitor on 2.3.0

I installed the newest Behringer driver manually, but that now provides 2X2 inputs for WASAPI instead of 1X4. I then went back to their older (3.29) driver, and got the 1X4 input back, but, for some reason, it will not save a change to sampling rate in Control Panel.

This problem with the Behringer UMC404HD drivers was also reported here: Installing ASIO in Audacity
It looks like they realised that they had problems with the multi-channel WDM driver, so replaced it with 2x stereo drivers (just my guess).

1. To record from an LP, I need to switch the preamp to Phono. At that point, HDMI video from the PC is no-longer being routed to the TV.

Perhaps adding a “manual HDMI switch” would solve this problem. (Equivalent to unplugging the PC from the pre-amp and connecting it directly to the TV).
Signal route:
Record deck → Pre-amp → SQ-W → UMC404HD → PC
and
PC → TV
