Comment 64 for bug 994685

OK, here's a quick update. I collected alsa-info data, for Joseph's fixed 3.2.0-26 kernel as well as for a failing 3.2.0-23 Precise stock kernel. For each kernel I did a collection with the headphones plugged in, and one without them. I'll attach them in a bit.

I also tested Herton's request to use alsa-info -D hw and play with the volume settings, with no change; indeed, as can be seen in the screenshot I'll also attach, the headphone volume isn't even controllable. The screenshot was taken with the headphones plugged in (this is why the speakers are "muted", so it looks like the kernel detects headphone insertion at least).

I'll next try to find kernels from which to start a bisect for the 3.0-3.2 transition.
