Bug Description
Binary package hint: gnome-media
Using either the panel volume control or the master volume slider in gnome-volume-
In the attached image, note that the 100% mark is only about 2/3rds up on the slider, this may be a significant part of the problem.
To reproduce the problem, the hardware tab setting must be in one of the 5.1 modes, the stereo modes don't seem to have this problem.
Also, individual application sliders do not seem to have this effect. If I tune the master volume to a point with no distortion I can manipulate the app specific volume controls and not introduce distortion.
maybe helpful info:
~$ aplay -l

I have distortion in 5.1 modes after upgrading from 9.04 to 9.10. The volume slider has some effect on it, but it doesn't disappear fully unless I use stereo mode. It happens with both HDA ALC1200 Analog and Creative X-Fi.
