Bug Description

I'm using a Compaq Presario 2107us Latop.
In Ubuntu 7.04, Volume Control was no issue; the QuickKeys (Volume Up/Down/Mute) on the side worked very well. Also the keyboard shortcuts (Fn/PageUp and Fn/PageDown) were equally smooth.
When I clicked on the Panel's Sound Icon, moving the volume slider was also smooth and accurate.

In Ubuntu 7.10 on the same laptop (a clean install, not an upgrade install), the Quick Keys and shortcut keys are erratic, meaning that a single tap of a key can one time mute the sound or move it to maximum. When I click on the Panel's Sound icon and move the slider up and/or down, the display on the mouse pointer alternates from a number (percentage) to "Muted" to a number to "Muted", etc.

I can make it work but it's very erratic.

I have the same problem with an Asus laptop:
The volume shortcuts do not work anymore on Gusty, the volume down cuts the sound and the volume up actives the sound.

What's the output from `asoundconf list`?

Please attach, separately, `amixer` output from both 7.04 and 7.10.

For me on 7.10:

Here are my results from 7.10...... unfortunately, I no longer have 7.04 installed, so I can't include that.

Thanks :)

This is has a 'LOW' rating, which I find insulting, quite frankly.

Beginning with the Hardy Heron 8.04 development cycle, all open Ubuntu kernel bugs need to be reported against the "linux" kernel package. We are automatically migrating this bug to the new "linux" package. However, development has already began for the upcoming Intrepid Ibex 8.10 release. It would be helpful if you could test the upcoming release and verify if this is still an issue - http://www.ubuntu.com/testing . If the issue still exists, please update this report by changing the Status of the "linux" task from "Incomplete" to "New". We appreciate your patience and understanding as we make this transition.
