It looks like you have the relevant mixer controls on. I have a Via VT8237 with a Realtek chip, and it plays on all six channels. However, the PCM and Master volume controls only affect the front speakers. Since mixer controls might not all behave as expected, you might try turning on (unmuting) and turning up all playback controls, even ones that seem irrelevant. Of course, try other stuff like switching output jacks, checking speaker connections, speaker/amp controls, etc. I also had to figure out the correct mapping of output jacks by trial and error, since the colors don't match the speaker plugs.
