Title:
[USB-Audio - USB Device 0x46d:0x802, recording] Sound is distorted
Status in alsa-driver package in Ubuntu:
Incomplete
Bug description:
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.
