And one more issue:
I use pulseaudio as system service, and veromix don't show all of playback streams, screenshot is here: http://imagebin.ca/view/kyw3og.html

It isn't shows mpd (running as service) and python streams, but show vlc.

Maybe it shows only new channels that created after plasmoid is added?

No, if I restart mpd, it recreates the stream, but veromix didn't show it :(

If I use pactl list, I see all this streams, but veromix show only some of them.

You could try to start veromix from the console, to see if an error-message is shown:

First kill the process called
"VeromixServiceMain.py"

Then start the service in a terminal:
Quote:

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

then in another terminal:
Quote:

cd ~/.kde/share/apps/plasma/plasmoids/veromix-plasmoid/

plasmoidviewer .

do you get some messages?

Does your project have any public bugtracker? If not, maybe time to create it for better solving issues? For example in Google Code (http://code.google.com/p/gmail-plasmoid/) or sourceforge?

And one more problem:
When I change the volume in plasmoid, real stream volume is not changed if I change it in 6-channel stream (Inernal Audio Analog Surround 5.1), but if I change channels to 2 (Stereo), it change normally.

Which volume does change this plasmoid? Volume for each channel in strem or base stream volume?

Yes there is a problem if an output has more than 2 (stereo) channels, e.g. like in your case 5.
sorry for that (until now I only knew that this is a problem for mono-microphones(e.g. 1 channel) ).

@pulse-audio as system-service: I never tried that.. will see what I can do about that..

Which volume does your plasmoid change in stream? As I see in pactl output, each stream has per-channel volume and base volume.
I think that better to change base volume, it have one value always, don't depend on channel number.

Example of output in my 5.1 channel:
Quote:
$ pactl list
...
Sink #3
State: RUNNING
Name: alsa_output.pci-0000_00_14.2.analog-surround-51
Description: Internal Audio Analog Surround 5.1
Driver: module-alsa-card.c
Sample Specification: s16le 6ch 48000Hz
Channel Map: front-left,front-right,rear-left,rear-right,front-center,lfe
Owner Module: 1
Mute: yes
Volume: 0: 31% 1: 30% 2: 42% 3: 42% 4: 40% 5: 28%
0: -30.57 dB 1: -31.52 dB 2: -22.61 dB 3: -22.61 dB 4: -23.80 dB 5: -33.01 dB
balance -0.02
Base Volume: 63%
-12.00 dB
...


And I can change the base volume using values 0-65535:
Quote:
$ pactl set-sink-volume 3 10000


If you try to detect number of channels and change the volume for each of it, it can give the problems that I describe here: http://bugs.kde.org/show_bug.cgi?id=254793 - if I set volume to 100% it breaks per-channel volume setup.

So, as I think, better is to change base volume and don't touch channel volumes.

pulseaudio as system service is better for me, because it can work without xorg, and I can control music via mpd before kde is loaded. And I can connect my notebook via wifi to 5.1 system without starting xorg session in main computer.

your icon-theme should provide icons for:

audio-volume-high
audio-volume-muted

If your monochrome icon theme provides these icons, you will have monochrome-icons in the panel. If not you get the default oxygen-icons.

is kmix showing monochrom icons - i think the plasmoid uses the same icons as kmix

Hmm I never realized that there is a base-volume, but the api says:

Quote:
pa_volume_t pa_sink_info::base_volume
Some kind of "base" volume that refers to unamplified/unattenuated volume in the context of the output device.

As I understand it, one cannot change that value. I use the function:

Quote:
pa_context_set_sink_volume_by_index

yes I should definitely go for one..

 Wish: Global Hotkeys

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.

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.

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)

How do you like Plasma 5?
 The best KDE Desktop ever.
 Definitely a nice improvement.
 Not decided yet. Haven't tried it yet.
 I do not like some of the changes.
 KDE is taking the wrong way.
 I am still sticking with KDE 3.5.
 I have no opinion, but wanted to vote anyway.
