Comment 55 for bug 580183

Okay - I've had a bit more of a thorough look.

If I shift the balance all the way to the left, the noise stops. All the way to right and center, noise.

Looking at the source code there was something about nomicbias which I'm hoping addresses the balance stuff though I'd have to get something from the microphone to get an idea of the balance issue.

So how do I go about getting the sound card working? By the looks of the source code, the only thing that differentiates the different models are verbs and more specifically, the vendor specific pins. HDA-Analyser is next to useless in this regard as it doesn't describe anything about what can and can't be set with with those pins.

Does anyone know how hard it would get to get that information?
