I got a problem with detecting sound card with Windows x

I use SDK function waveInGetNumDevs() to test if there is a sound card. But even if there is no sound card installed, the function still returns 1. And even waveInGetDevCaps() returns no error. I checked device->hardware, and there are some items under "Audio, Vido and game" catogary, they includes
"Legacy audio driver",
"Audio codecs
"Media Control devices
Guess there are some onboard Audio support, but no sound card installed

SO how can I detect if there is a sound card installed or not? Can anyone help me
Thank

Your post is off-topic here. You should post again in

It doesn't matter if the sound support is on the system board or a card. If
the driver finds suitable hardware and initializes it so that there is a
device available to be used then the function counts it.
