Making the API call to beep() would be less CPU intensive than a sound driver. My understanding is there used to be (Win98 and before) sound drivers available to use the internal speaker, and you could even play .WAV files. However, with no sound card, the sound driver would have to use the CPU to create the sound.

And, the CPU would be tied up until the sound finished playing...

Ideally, an app would check to see if a sound card (or driver) is installed, and would call beep() (instead of ? chr(7)) if there isn't one.
