Lsmod and modules.conf do not show any problem to me.

You are most certainly playing a mono signal through the OSS emulation
layer. With hdspmixer preset 1, you should have signal coming out of all
the physical outputs, and also a VERY LOUD signal on the line outs, as all
the playback channels are routed to the line outs and thus summed up.
How is the card wired up ?
Do the meters show signal going through the outputs (3rd hdspmixer row) ?

As a side not, if you want to use alsaplayer with the alsa, you must use
the plughw interface :
alsaplayer -o alsa -d plughw:0

This looks good to me.
