There are some .wav-files in my experiment. But some users (with Windows-Laptops that are a bit older) cannot complete my experiment (it's completely screwed up instead), because of the following error:<br/><br/>DirectSoundError - 2147467263&nbsp;the function called is not supported this time.. line 99, file/win/soundplayer.cpp<br/><br/>Others users with Windows-PCs and Mac-Users report no errors... Does somebody know this problem or has some ideas how to solve it?<br/><br/>Thank you,<br/>MartinaThu, 12 Mar 2015 08:18:09 GMTMartinaThielehttps://forums.millisecond.com/Topic15754.aspxIt's likely a driver issue on those older machines. The error # you reported suggests a problem with processing of float data. See e.g. for something similar: <a href="http://microsoft.public.win32.programmer.directx.audio.narkive.com/elgNlPIn/playing-float-samples-with-directsound">http://microsoft.public.win32.programmer.directx.audio.narkive.com/elgNlPIn/playing-float-samples-with-directsound</a><br/><br/>Not much you can do about that on your end. People would have to make sure the soundcard drivers on their boxes get updated.<br/><br/>The only alternative you can try: Convert your WAVs to e.g. MP3 and use the &lt;video&gt; element (not &lt;sound&gt;) to play those.<br/>Thu, 12 Mar 2015 08:18:09 GMTDave
