I use the VB-Audio + RTL dongle with SDR# on my Windows 7 desktop with no problem. On my Toshiba laptop running Windows 10 after a couple minutes of working fine the VB-Cable stops working. In the Recording Properties tab for the virtual cable the level is set to 0 and the speaker symbol is muted the apply tab in the window is greyed out. If I change these they go back to 0 & Mute. In the volume mixer window multiple Microsoft Register Servers appear all set to 0 & mute. does anyone know what is happening????
