Original bug at Ubuntu: https://bugs.launchpad.net/ubuntu/+bug/252237

The problem is, the volume control skips around and jumps to zero sometimes
when adjusting it.

I limited the problem down to the ext/alsa directory of gst-plugins-base.

The problem is introduced sometime between 0.10.12 and 0.10.14 or at 0.10.14,
and it still exists in 0.10.18.  I believe this commit is at fault:
