Detection of Sound Installation

[tkroeckel]

Hello,

I'm searching for a reliable way to detect if a target-system has a correct installed and enabled soundcard.
My setup requires this information at startup, otherwise I have to inform the user that installation will not work properly afterwards.
Any help is appreciated,
thx in advance

Here's the thing. Just because a sound device is installed won't necessarily indicate that the user can hear your application. I would do one of those quick sound tests which just plays a sound and asks them to click one of two buttons, "Yes I heard the sound" or "No I didn't hear anything". That's the only way to know 100% for sure if the user can hear your app. My two cents. :yes

Hi Corey,
a very "reliable" and extremly save way.
Thanks a lot

Should tell you if they have a soundcard or not, but it can't tell you if they have speakers

nReturn = DLL.CallFunction(_SystemFolder.."\\winmm.dll", "waveOutGetNumDevs", "", DLL_RETURN_TYPE_LONG, DLL_CALL_STDCALL)
if nReturn == 0 then
	--no soundcard
end

I don't want to take over this thread or anything, but I have been looking for a way to detect the names of the installed audio devices. Worm, maybe you can help me using that winmm.dll?

Thanks.

Superb!

Thank you very much! :yes :yes

Oh one thing. Is there a way with this DLL to detect the current default Windows device (as per the Control Panel)?
