The 1/4" outs are balanced and can not be trivially connected to PC
speakers. Balanced connectors use a ground reference and a pair of
differential signal lines.
To connect you need the right cables such as this one:

That is a stereo RCA to unbalanced TS cable.
The manual from emu even mentions it. You can get the PDF at the emu website here:
http://www.emu.com/support/files/storage/1820_1.81_(EN).pdf
The 1820 and 1212 are related.
Or you could use something like this:

That one is easier to use for pc speakers since it has a 1/8" stereo
jack rather than RCA jacks.

Did you remove any saved settings for alsa that were left over from the
sb live? Maybe that is confusing it.

Maybe you should get something more current. 2.6.22 has full alsa
1.0.14 for example.
What do you see in /proc/asound/cards ?

It may or may not be good enough. The support was supposed to be in
2.6.14 but rc2 may not have had it yet.
