Play multiple sound files simultaneously to different outputs

[KjetilSteen]

Hi!

I want to play multiple sound files simultaneously to different channels using an external sound card. I have no problem accessing the sound card, but I can't figure out how to make the four stereo tracks play at the same time. Is this even possible in LabView?

Hi Kjetil,

as the context help explains you should be using an array of waveforms...

I know how to generate sound, but what I can't figure out is how to make LabVIEW play four stereo tracks at the same time to four different outputs.

Hi Kjetil,

did I understand you correctly? Using one soundcard which provides 8 channels?

Playing an array of 8 waveforms should do the trick.

If it doesn't work: does LabVIEW "understands" how to play more than two channels on this soundcard? Does the card provide a "standard" OS driver? Does it need special software to play sound on those 3 other stereo channels?
