Hmmm, The error happens when alsa tries to set the parameters for the
output stream as a whole, it does not do that for each channel (alsa does
not work like that). Alsaplayer may be trying twice to open the stream
for all I know.

Hmmm, you mean you get only one message and it is exactly the _same_?

If you installed alsa-tools there should be a program called envy24control
that could come handy. I don't have a 2496 so I don't know for sure which
options will appear on your screen... So, start envy24control. Click on
the "Monitor Mixer" tab and see if when you play you see the meters move
on the first two channels. If you do then the problem is levels on the 
mixer. If you have a tab named "Analog Volume" verify that both DAC0 and 
DAC1 are up.
