While that's uncompressed, it's not the *raw* data needed by the sound
device, it's formatted data, so you'll still hear noise.

I can't say that I know what raw format would be needed, though.
Someone else would have to chime in about that.  This is why we have
device drivers, to provide the particular data wanted by the hardware.
