Detecting soundcard

[faire]

Is it possible to detect whether a user has a soundcard installed? My app has some background music, but it shows some nasty errors if there's no soundcard available. Of course I've made a "-nomusic" switch, but it would still be better if I could detect whether a soundcard is available. Perhaps there's a registry key somewhere that I can read..?

$NumberOfSoundCards=DllCall("winmm.dll","uint","waveOutGetNumDevs")
MsgBox(0,"Number of sound cards is:",$NumberOfSoundCards[0])

[faire]

$NumberOfSoundCards=DllCall("winmm.dll","uint","waveOutGetNumDevs")
MsgBox(0,"Number of sound cards is:",$NumberOfSoundCards[0])

Sweeeet. I can confirm it works, because I have 2 soundcards and it in fact returns 2.

If you don't mind me asking, how did you find out which DllCall to perform?

Edit: aha, MSDN: http://msdn.microsoft.com/en-us/library/ms713748(VS.85).aspx. I can see how that fits together with the command.

As with a LARGE number of questions on this forum, I simply ask google the same question, (often appending a 'VB' to get programing related results) and then convert the answer into autoit.

search phrase: detect a sound card VB

first result.
