Running with my old computer a USB digital 7.1 external sound card I was able to either listen to my music through my 7.1 Anthem amplifier or with my Sennheiser wireless analogue standard 3.5 stereo headphones with a 3.5 analogue stereo microphone connected for use with Skype etc without having to change things within the control panel. Does anyone know of any reasonable quality 7.1 HDMI, coaxial or SPDIF /optacle digital plus analogue PCI sound card which would achieve this result? Thanks Brian
