AudioDeviceManager open Primary Sound: error -2004287480


Every once in a while I get the following error at AudioDeviceManager initialization:

Error opening Primary Sound Driver: “Unknown error: -2004287480”

At other times, Primary Sound Driver opens just fine. Is there a way to decipher this error code?

Well, have a look in, and there are a few things you could try. A breakpoint at the line 218 should show you what DSound call triggered the error, though if the device is sending a crazy number back, then only the people who wrote the sound driver could help decipher what it actually means…
