if anyone know how to connect a pc to this receiver , then let I know ... there be only 2 input -lrb- one analog -rrb- and one supposedly digital , but the digital optical imput will not connect into my pc spdif for sound , so I can not run sound from a pc through the receiver . what be worse be that the speaker be all run off the power subwooffer , so it only will support this receiver ... really upset with this purchase consider they never provide a upgrade patch ...
