UMC202HD + Win 10: Everyone hears me + piano perfectly. But I don't hear them!

Have you setup port forwarding in your router?

Hi Chris, 
yes, I have set up port forwarding to ports 12000-12001.

In any case, I was able to hear my co-musicians when I tested with built-in speakers, rather than UMC202HD output.
But that is not a sustainable setup, as latency and frame size are not good with WDM drivers.
I definitely want my sound to work in and out of the UMC202HD, using its ASIO driver.

So that is why I'm trying to solve the buffer setting and resetting problem.
Do you think there might be some connection between port forwarding and that problem?
