I'm not sure if anyone can help but I guess this must be common problem. I have Focusrite 56 Liquid rackmount soundcard which keeps switching off in Windows 10 so get no sound but machine is still switched on. This happens every 20-30 mins which is driving me insane. I have checked power options and disabled PCI Express as think this maybe issue but still keeps happening. I have re-installed mix control few times so this cannot be issue, as does work on reboot but I want it too never turn off.
