E-Prime Device Sound Error

[Trishala P]

Hi all,

I just installed E-Prime 2.0.8.22 on a Windows 7 computer. The program is installed, but when I try to run an experiment file I get the following error:

Device name: Sound

Error: 0x00000385

Unable to create the directx object: 0x88780078

I don't have any sound files on my experiment and don't need sound so not sure why this is happening. The file ran on another computer with the same specifications, but not on 2 other computers.

You might try disabling the Sound device.

Alternatively we found that on some PCs the Sound device gives an error unless headphones or speakers are plugged in.... Even if the experiment does not use sound. So attaching headphones might also do the trick.

You might still want to use sound for a later experiment, so best to get
this fixed at any rate. If you search through the forums you will find
that EP2.0.8.22 was known to have problems with sound & movies under
Windows Vista & 7. You should update to at least 2.0.8.90, or even all
the way to 2.0.10.242. You have already paid for those updates.

You might also contact PST Web Support for more specific help.
