Sure can. The function waveOutGetNumDevs returns a Word with the number of
wave output devices installed. Non-zero results should be a safe bet.

Re:Detecting a Sound Card

Don't ask about details, but the most common way is to query the multimedia
for the presence of wave-audio equipment and use that.

A good place to look would be the calls for MMSYTEM.DLL.
