It was an app I wrote. I used 32 bit float format, 32 bits per sample, 32 bit container. There's an example wave format struct on MSDN.

And which application are you talking about,did you remember which format you selected in your app (driver == float format):-24 bit (32 bit container) -24 bit -16 bit -32 bit float Thanks, /Uwe Matt Gonzalez schrieb:I've used it for recording in an application.

If I select a 24 Bit audio format in my application (wavelab), there is only silence recorded.16 Bit format recording seems to be ok though. Is this a (known) issue within the windows XP kernel mixer?
