Are you sure your hardware supports 6-channel output? There are several version of the 8738 chip (with/without spdif, 4/6 channel). The chip should read something like "CMI8738/PCI-6CH".
Furthermore, it requires some extra hardware (analog multiplexers, for example a 4053) to switch the connections. Maybe the manufacturer left that out (to save a few cents).
