In natty the sound on this device was flawless. On a fresh install of Oneiric I sound more like Alvin and the Chipmunks. I've tried plugging in a headset on the off chance that it was a device driver at fault no joy. So it can only be a codec (but you'd have more reports) or an issue with the onboard soundcard driver. I'll have and tinker and report any improvements here.
