Slider movement direction in Ubuntu inconsistent when using mouse wheel

[Mario Vukelic]

Binary package hint: indicator-sound

In LP#725160 and LP#725167 I reported inconsistent wheel direction issues for particular sliders, but now I realized there is a wider issue and thought a separate report is in order. I see the following behavior on up-to-date Natty:

Indicator and indicator menu:
Forward (away from me): increase volume
Backward (toward me): decrease volume

K3b (only KDE app I have installed) is the same. I tried menu Settings -> Configure K3b -> Plugins -> K3b Ogg Vorbis encoder -> Quality level

However other sliders use "Forward (away from me)" to DEcrease, and "Backward (toward me)" to INcrease whatever value:
gnome-power-manager: set brightness
gnome-screensaver: time to idle
tracker-preferences: all sliders
gnome-window-properties: time to raise
Gimp: all filter sliders I tried
And so forth

It seems that sound indicator is the odd one out, which is why I filed it here. However, to me the sound indicator behavior seems more intuitive and so I guess the bug may be elsewhere. K3b behaving the same as sound indicator may be a sign for that.

In case it matters, I use a Logitech Cordless TrackMan on an Apple MacBook Pro 5.34 the trackpad scrolling of which works exactly as the wheel.

Sorry, can I edit the subject line? There's a typo, "insonsistent" -> "inConsistent"

*facepalm*

thank you for your report - please reopen if this issue still exists in 12.04

[Mario Vukelic (kreuzsakra)]

Yes, the same issue still exists in Precise Beta 2. In addition, the sliders in System Settings -> Sound do not react to the mouse wheel at all anymore (but the slider in the Sound Indicator still behaves as described in my initial comment)

Status changed to 'Confirmed' because the bug affects multiple users.

This is a question for Ayatana Design and is not an ido / indicator-sound bug -- they are behaving as per the specification. <https://wiki.ubuntu.com/SoundMenu> "Whenever the volume item is highlighted: The Left and Right arrow keys should instantly decrease or increase the volume, respectively, to the nearest 5 percent step. "

And, as the original description says, it would be counter-intuitive to have the volume levels work the other way around.
