This is often true under working systems. You need a wav player to
really play wavs... It does something a bit more sophisticated than 'cat'.

Again, some software is useful here. sox is a well known sound package.
What you get from the devices is some raw format, not a well-formed
sound file containing a header about the encoding, sample rate, etc.

What does `cat /proc/sound` (or /dev/sndstat) say for Synth Devices?
Do your system logs complain about not being able to find a module for
synth0? I believe the opl3 driver is in the adlib_card module (though
this may vary), does /proc/modules indicate that it is loaded?
