Shaun Hayward Posted August 15, 2011 Report Posted August 15, 2011 So, I'm trying to access a bit of the DirectSound API from LabVIEW. This is because I have multiple sound cards on my system (with the same name) and need to identify them. The built in functionality / "Device ID" technique falls down as sometimes the device IDs can change. Our goal is to use the GUID of the device to identify the device in a more unique, and reliable way (once I have the GUID, I can to a few other tricks that work to make things friendly to my test system). HOWEVER, when I try to create the DirectSound "DevicesCollection" object to enumerate my sound devices, I get the following error: Any ideas? Quote
