Does mouse whell on icon works for you on KDE 4.5? It changes the volume?

Report

nik3nt3
10 years ago

Yes, it works for me (kde4.4 at home and 4.5 at the office)..

@mpd:
Thanks for your debugging. I will fix that problem tomorrow..

@volume:
Quote: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.

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
http://0pointer.de/lennart/projects/pulseaudio/doxygen/introspect_8h.html

@bugtracker:
yes I should definitely go for one..

hy

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

Hey, i'm using the default plasma theme, which provides those icons and it still is the colored oxygen icon when i use it on the panel :)

the plasma-theme is not providing icons - the icon-theme should provide these icons...

as far as I know, tray icons are plasma-theme dependent ;) You should really switch to this. :)

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?

Report

nik3nt3
10 years ago

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.

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?

Report

Murz

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?

Thank's for new version!
Middle click works perfectly! But mouse whell don't want to work :(

KDE 4.5.2, Kubuntu Maverick.

And another issie is that when I add plasmoid to panel, at first time it added full size (not iconized) but after clicking on channel image, it converts to icon.

Report

Murz

Very good plasmoid, thanks!
But can you implement feature to mute/unmute channels (select which channel must mute in settings or mute all channels) via middle-click mouse on plasmod (when it is iconized in panel)?

And will be good to change volume of favorite channel via mouse whell on plasmoid icon! Did you plan something like this?

nik3nt3

Thanks for your input: It works! Will release a new version soon.

[Don't understand why it was not working the last time I tried it. Maybe a KDE 4.4 vs 4.5 difference or just my disability ]

While on a whole am mostly indifferent and had not even noticed the issue till u mentioned it. I think for UI consistency it would be nice if all the meter icon stays in one side and the icon same. having the meter for the default volume slider at a different position other than the applications breaks consistency somewhat. Just IMHO
