Swapping between 2 drivers

This should be a simple fix

I have 2 devices attached to my PC,
UR44 with headphones (yamaha steinberg USB driver)
computer monitor (Generic low latency ASIO)

I have recorded a lot of songs at 96k 24bit which sound good with the ur44 but when I switch over to the Generic low latency ASIO driver I have 2 problems

#1 Everything plays at half speed
#2 Volume is at 100%

How can I rectify this , ta
