Stephan Kappertz Sound Cards & Media Devices Drivers

Hi Stephan, There is a way to first check if a computer has a sound card. Try to use WaveOutGetNumDevs and WaveInGetNumDevs - they return the number of audio playing devices (Out) and the number of recording devices (In). Try to use it like this: if WaveOutGetNumDevs=0 then application.messagebox('Error', 'No sound playing card', mbOK). $72 / €64 / £56.

is soundcard?

hi is there a way to first check if a computer has a sound card before i try
to play a sound, i have some users who don't have sndcards, and this creates
an error on their systems.

i tried using the sndplaysound api aswell, but this creates the same error

thank you

Re:is soundcard?

With a try Except block try to create a TMediaPlayer object and then test
boolean value like (mpCanPlay in MP.Capabilities)

Hi Stephan,

There is a way to first check if a computer has a sound card.
Try to use WaveOutGetNumDevs and WaveInGetNumDevs - they return
the number of audio playing devices (Out) and the number of recording devices
(In).

Try to use it like this:
if WaveOutGetNumDevs=0 then application.messagebox('Error', 'No sound playing
card', mb_OK);
if waveInGetNumDevs=0 then application.messagebox('Error','No recording sound
card',mb_ok);

The best place for this code would probably be in the On Create handler for the
form.

What kind of sound do you want?

Re:is soundcard?

thanks, i will try this, but i think i have come right with the sndplaysound
api,

i have a small autorun app which my company uses on cd's created with
information for our customers, it plays a bit of sound on start and end, and
on the click of the links
