For getting sound to all speakers I use gamix. I'm sure you can also use
the console based utilities. 
In gamix 
1) Duplicate Front (checked)
2) Surround Enabled (checked)
3) Surround unmute (checked) and get same gain on the channel
4) Line-In as Surround (checked)
5) VIA-DXS - Full gain(don't know why, but xmms freezes if not set)

You also got some settings for reverb/echo effects

Hope this helps, 

Good luck
