To keep my Softrock RXTXs working I had to use multiple instances of HDSDR and virtual audio cables. I could not find suitable internal sound devices so had to accept that USB devices would have to be used. I wanted something that would replace that and run the latest wideband SDRs so purchased a Dell XPS 8930 with a Core I7-9700 and Nvidia GeForce RTX 2060. This had the equivalent of about 10 stereo audio systems including a M-Audio 1010 and 2 Delta 44s.
