Just in case it is not working yet: You should install the package "python-xdg"

Hi,

Stock Kubuntu 10.04 64bit (so KDE 4.4.2).
I had to add VeromixServiceMain.py to autostart, but after that, the plasmoid worked great (and it is very nice).
However, when I try to enter the setup setup (Alt D, S), nothing happens.
Probably related: I also cannot put (move) the plasmoid in the tray.

i will check that - has the plasmoid created the file ~/.local/share/dbus-1/services/org.veromix.pulseaudio.service ?

Quote:However, when I try to enter the setup setup (Alt D, S), nothing happens.
There is no settings-dialog .-)

I don't think that plasma supports moving plasmoids to the tray - you have to open the config-dialog of "system-tray" plasmoid and enable the plasmoid there.

No. I installed it by downloading and then installing it in the Plasmoid selection screen using 'from file' or someting like that.

Well, the installation of the plasma package failed... (throught add widget, installation using file etc...), installation via internet fails too.
Using KDE4.5 rc2, Kubuntu x64 10.04.1

Thanks but it didn't helped, it still cannot be installed (even I use KDE4.5 version of veromix) by any way :/

silly me, it works, I just had to uninstall last veromix from /tmp/.../ and install KDE4.5 version again...

So installation is OK, but the widget is empty, no sliders, no icons, I use PulseAudio on Kubuntu 10.04 and pavucontrol shows the volumes right...
Does anyone have the same issue?

Hi

Looks like the my dbus-adapter is not running: Check if there is a process called VeromixServiceMain.py
Quote: ps -ef | grep -i veromix

You might want to check what is happening when you start this process manually:

Quote:python ~/.kde/share/apps/plasma/plasmoids/veromix-plasmoid/dbus-service/VeromixServiceMain.py

If that works, check if this file exists:
Quote:~/.local/share/dbus-1/services/org.veromix.pulseaudio.service

you can also add VeromixServiceMain.py to the autostart of kde.

/nik

@VeromixServiceMain: I separated the pulseaudio stuff from the plasmoid because I had big problems with crashes.. So VeromixServiceMain.py connects to PulseAudio and sends info over dbus to the plasmoid(s)

Hi

You can add the VeromixServiceMain to the autostart list of kde systemsettings. But make sure that pulseaudio is started and running before VeromixServiceMain.py. Otherwise it will not work :-(

You might first want to try to create the file manually. You will find a sample on my new troubleshoot page: http://code.google.com/p/veromix-plasmoid/wiki/VeromixComponents

hope it works

well, there miht be a bug in Kubuntu because the pavucontrol cannot be started (-connection failed:refused- bug)without "pulseaudio -vvvv" in terminal...
So, I reinstalled veromix to latest version (0.8.4) and situation is the same: no sliders, just blank plasma frame with nothing. So, I have to type the command you told me. Also, I do not have the file you mentioned so should I create it? What should be in it?

But, the icons and sound sources are then shown correctly in veromix :o)

So the only problem is I think there is not the file of veromix created...

And bug in ubuntu that needs to run "pulseaudio -vvvv" in terminal.

Does the plasmoid show the same sources as pavucontrol?

instead of it is nothing :) it is without text, I have text just on simultaneous output. Of course, I have it as default ;)

What is written instead of "Amarok"?

Make sure that Pulseaudio is the default Output-Device (check systemsettings -> "Multimedia". I've set Pulseaudio to be the default output-device for all audio-sources).

And is OK that I haven't Amarok icon next to it's volume bar? And no text "Amarok", both like you have in screenshots? :/ sorry for anoying questions

Thank you, I haven't this file (I do not even have dbus-1 folder :o) but the command to start veromix manually works so I'll add it to autostart. Althought my Pulseaudio is probably broken in my ubuntu because doesn't recognize more sources of sound than one (e.g. Amarok and Opera etc.), so I'll have to consult it with launchpad bug reportings :D
But anyway thank you :o)

Can you add ability to change default output device? Like one in gnome sound preferences → output or in kde system settings → multimedia? That would be nice.

Thanks for this beautiful plasmoid, it very useful for me!

But I see an unnecessary horisontal scrollbar when veromix is in tray popup window:
http://imagebin.ca/view/Lz5CNy.html
And how I can change the width of plasmoid popup? Because the volume line is too short! On desktop I can tune the size: http://imagebin.ca/view/UITVhEh1.html but in tray - can't.
"Veromix Settings" menu item didn't work.

Wait for new versions...

Hy
you can change the width (and also the height) of the plasmoid in the top right corner: Hold the mouse over it and the mouse-cursor should change to a "double-arrow", then click and resize the plasmoid... (this is actually the default-behavior for popup applets, and I don't know how to change that: e.g. resize-handle on every corner of the applet)

The width an height are not stored, that means after the next reboot you have to set the width and height again - I will improve that in the next version (also making it smaller does not work well)

There is no Settings-Dialog for veromix - I don't know why plasma shows the settings-icon eventhoug the plasmoid declares that it has no settings.. (will check that for the next release)

This really is a great piece of work, and makes it really easy to adjust volume levels however there are a couple of features I think would really make this a cut above the rest.

1) Rather than clicking on the icon just muting the stream it would be nice to have the additional choice of which sink you want the audio sent to. In my case I sometimes, but not always, have a bluetooth speaker system that I want to send amarok sound to yet keep all other sounds on the system speakers.

2) Have a configuration option to select which sinks to show/hide.

3) Perhaps an option just to show inputs or have a tabbed system - "All - Sinks - Applications"?

Thanks again and keep up the good work!

Thanks for your post, this motivates me to continue my efforts eventhough I'am stuck with the current situation:
I spent days and nights to fix the bug mentioned in the plasmoid-description, without success. I'am not sure if the bug will ever get fixed (I pretty sure it's a python-bug)!

I'am still undecided if I should reimplement that plasmoid in C++ or ignore the problem and later switch to a better solution (when the pulseaudio dbus-interface is ready) or just ignore the problem at all.

When I decide to continue I will surely implement some of your proposals.

But why do you want to hide some sources? Which sources would you hide?

Hi,

I am running KDE4 trunk and I am unable to use this plasmoid. I can install it successfully, but it doesn't show up in my pkasmoid list. Strangely enough I can run it with plasmoidviewer veromix-plasmoid and it display fine.

Adding it manually to plasma-desktop-appletsrc, delivers the following error message :

plasma-desktop(15391)/libplasma Plasma::Applet::load: offers is empty for "veromix-plasmoid"
plasma-desktop(15391)/libplasma Plasma::ContainmentPrivate::addApplet: Applet "veromix-plasmoid" could not be loaded.
plasma-desktop(15391)/libplasma Plasma::AppletPrivate::init: Check your constructor! You probably want to be passing in a Service::Ptr or a QVariantList with a valid storageid as arg[0].

and the plasmoid is not shown.

At this moment I am not sure if this indicates a bug in plasma from trunk or that trunk requires something additionally from the plasmoid. At the moment I am checking with the plasma team, but would appreciate also your feedback.

Thanks

Regards

Raymond
