[alsa-devel] missing control in alsamixer capture for CA0110-IBG

I have a Creative X-fi pci card (HD-Audio Generic) that uses Creative CA0110-IBG. Under alsamixer / Capture, there used to be two adjustments / sliders. The first was for "mic" and controlled the volume. I don't remember what the second was called, but it was very useful. It's default setting was "0." But recording worked ideally if it was to one notch above "mic." I used to set them at 45/46 respectively.

Anyway, this handy adjustment / slider vanished a couple of weeks ago, and I was wondering where it went? Now I only see one slider, for "mic" and the performance of my microphone isn't as good, and I have to turn it up louder.
