I have 3 pieces of this cable as connection between 5.1 system (Logitech Z-5500 5.1 THX 505 W RMS HiFi speaker surround system) increased and PC.
Unfortunately, in addition to the cables, the connectors are relatively wide so that two plugs fit both the motherboard and the Z-5500 not coexist. If you're lucky, the sound outputs can switch on the motherboard to some space to create. I had to use a thinner short extension between the mainboard or Z-5500.
