All,
I just indulged in a highly rated 192kHz USB sound adapter. It's a Behringer "U-Phoria" UMC202HD. For use with the Softrock, I had to get a couple of mini-stereo-phone-plug to two 1/4inch phone plug cables.
Unfortunately, I couldn't get it working. Rocky fails with various low-level OS complaints - stuff like "wrote to an illegal address". HDSDR won't even start the radio. This is on a Windows 10 desktop.
Just on ordinary Windows, it works fine as a sound output device. Delivers absolutely gorgeous sound to my Bose QCII headset.
