Hum, I actually meant rather the ability of using the Fn-keys for lowering or raising the volume..that would make veromix perfect for me :)

hmm - you can assign any key (-combo) you want. Is kde not recognising your FN-Keys?

AFAIK, you would need to go to #kde or #kde-devel in freenode and talk to the devs, to see how you could submit this to kde upstream, prolly it would go to the playground repo first, but i think this would be a very useful addition to main KDE :)

best regards :)

ps, im still missing the ability to up the volume above 100% (like gnome volume), besides that im happy as a clam :D

im only able to do it with the gnome volume control, pavucontrol doesnt appear to have that feature, maybe its gnome only?

I can start plasmoid with
~/.kde4/share/apps/plasma/plasmoids/veromix-plasmoid/dbus-service/VeromixServiceMain.py
and
plasmoidviewer .
and it works fine in a window but if i try to add it to the desktop it shows me a box with:
Object could not be created...
Script initialization failed

strange as it works with above commands....

There is a problem with the ~/.kde/share/apps/plasma/plasmoids/veromix-plasmoid/metadata.desktop file of veromix and your environment.

Which version of KDE and veromix are you using?

In KDE 4.4 metadata.desktop should define:
ServiceTypes=Plasma/PopupApplet

In KDE 4.5 and above:
ServiceTypes=Plasma/Applet,Plasma/PopupApplet

Newer versions of veromix implement a workaround for this bug. But I looks like it's not working in your environment.

Maybe it helps if you uninstall and reinstall it using:
plasmapkg -r veromix-plasmoid
plasmapkg -i <downloaded file>

If that does not help you might want to check ~/.xsession-errors for more info about the problem.

Can we continue discussing this issue here: http://code.google.com/p/veromix-plasmoid/issues/list

can you try to launch plasmoidviewer not from the veromix-plasmoid directory:

cd /tmp
plasmoidviewer veromix-plasmoid

does it also fail and if yes: o you get some debugging output?

On debian it fails perhaps, because the package:
python-xdg
is needed (it was the error on my system.)

I cannot get this to work on Arch Linux.

I have plasma-scriptengine-python as its part of kdeworkspace
and I have Pulseaudio installed.
but I dont know about python-xdg
as I google and cannot find any refernce to it.
When I try to load the widget I get the following message:
There is a problem with the background-service.
If you just upgraded try killing the process VeromixServiceMain.py
If you dont know how to do that try restarting.
I end up with a giant speaker icon that does nothing.

Thanks.

Hi

Most probably you are using python 3 (which is not supported).

I added your reports to my bug-tracker:

http://code.google.com/p/veromix-plasmoid/issues/detail?id=12

and

http://code.google.com/p/veromix-plasmoid/issues/detail?id=13

Can we continue discussing this issue there? (I already posted a possible workaround for the problem there)

I tried to run the command stated up the page to help troubleshoot and I get the result of:

This plasmoid is really nice! :)

One thing I'd like to have, though, is to be able to assign global hotkeys with which you could increase/decrease the volume of and mute the default audio device so I can use the media keys on my keyboard (as I can with kmix). Of course this should also show the same/a similar OSD as kmix.

This works perfectly for me with the Hotkeys of KMix..
Configure your hotkeys for KMix and the plasmoid will react on volume-changes..

Even if you close kmix? What KDE version do you use? I use:

Qt: 4.7.0
KDE Development Platform: 4.5.2 (KDE 4.5.2)
KMix: 3.7

When I close kmix and press the keys with which I change the sound using kmix (mediakeys on my keyboard) nothing happens. Mainly I want a replacement for kmix because sometimes it hangs with 100% CPU usage. Also being able to change volume per application with the sound applet is pretty neat.

However, there is another thing:
When I scroll over the popup window of your applet I would expect the volume of the slider I scroll on to change. Instead the sliders them self move out of sight, just to move in again.

first of all this plasmoid is very cool!
what i'd like it to have is autohide function after moving the mouse away (so it'd be not necessary to click on its icon to close the window)
