In the 11.4 product highlights it says: “…availability of PulseAudio in a Plasma Desktop session by default”, but what does this mean to the average KDE user? The SUSE-Wiki has no entry for pulse nor pulseaudio.
While basic sound works fine out of the box for me, I am confused between Phonon, KMix and PulseAudio. Each does something else:
KMix is now entirely useless, right?
Phonon only allows me to select which sound device is used for which input.
PulseAudio allows me to select indivdual volume per Application through pavucontrol, but it does not replace phonon nor Kmix
There is no KDE Plasmoid/Systray thingy for configuring volume with PulseAudio?
Is there no single application/plasmoid to handle all sound options in one go?
I think it is pretty bad that pavucontrol is not even installed for KDE-users by default, and it took me a while to figure it out. Or is there another application that a KDE-user should rather use by default?
I mean things work fine, such as using Phonon to automatically choose my Bluetooth headset for voice communication while music and games at the same time automatically use the speakers for output. Changing volume with pavucontrol works, but why do I need separate things for that?
This is not meant as a rant! I am just wondering whether the PulseAudio/KDE-Integration is just work-in-progress, or whether I am missing something important here entirely. After all, 11.4 and KDE 4.6 looks pretty polished to me overall, and so the audio situation sticks out as odd to me.
Kmix’s new interface adjusts for use of pulse audio. Whenever you’re using a new application that can have its volume controlled (amarok, vlc, a flash video in the browser) it will show up in the playback streams tab in kmix. Thus you can control the volume of each application individually. You can then use kmix’s audio setup option to get to phonon to change what devices to use for what situations, so really it’s all the same as before, it just has a different interface.
@ijbreakey is right about KMix. That “audio setup” option takes you to the same settings page as System Settings>Multimedia>Phonon (available from main/start menu’s Favourites tab).
So now you have learnt that KMix is not entirely useless.
Phonon allows you to configure Audio Output and Capture device preferences, speaker setup, and the order of preference for supported backends (phonon engines) e.g. Gstreamer and Xine. The idea is that phonon backends can be switched on the fly, to get the best results for a particular audio application.
I haven’t needed to install “pavucontrol” to have excellent audio with KDE and PulseAudio enabled on my hardware. Some users appear to have got around problems by using pavucontrol. Once setup, I have rarely needed to access KMix and Phonon settings. However with 11.3, I used pavucontrol on Gnome as the main/only option. KDE obviously preferred to integrate PulseAudio into their existing interfaces and tools.
With PulseAudio, KMix runs from the system tray (audio speaker icon) and a left-click will show the master playback channel for volume adjustment (slider), muting (button), and the mixer button.
Ok, thanks, then something is just wrong with my installation only, since KMix doesn’t work for me.
Initially, I only tested the mute button, which just changes the KMix icon in the tray to an outlined speaker, but sound continues on all devices unchanged. Changing the master volume does not work either. (Selecting the main channel has no effect on this, I tried all three options available to me.)
However, thanks to your replies, I now realize that output streams are actually shown in the mixer and their volume can be set indeed. I had missed that entirely, since when no sound is actually played (Amarok just open, but stopped), the play-tab is completely empty (I would expect at least a master-channel).
Furthermore, input streams that are listed in pavucontrol are not seen at all in KMix, for example my built-in mic does not show up anywhere.
Configure channels is always empty, and I only see two tabs for playback streams and input streams. Unfortunately, I now closed the (empty) input streams tab, but clicking on the new tab symbol in KMix just gives me an error message (Invalid Profile)
I was also aware of the possibility to start the Phonon config dialogue through KMix, but since I did not realize KMix having any function, I though on rather starts phonon directly.
Does anyone have a suggestion how to fix my KMix? Can I just delete its settings somehow?
I just deleted all files containing “kmix” from the directories .kde and .kde4 and restartet KMix.
Now everything works perfectly: All sliders are there, no longer just empty tabs. KMix actually works nicely!
Thanks to all the replies above! I did not know that this should have worked nicely. I was close to just blamed it on KDE4 and abandon KMix.
I wonder how many other of my minor gripes are due to outdated config files, but then again, who wants to change all those settings for every new SUSE version? I understand that complete sanity checks for config files are pretty hard to do.

if i had this problem, i’d just create a new user with every release and
see what’s different.
After installing 11.4 and having Audigy 2 ZS (i guess following applies to other Audigy/Live cards as well), I noticed that most of the hardware sound controls/channels (front, centre, side, rear and especially LFE (base) which in most of the cases is tooooo high) are no longer shown in the default (PulseAudio-based) Kmix interface and also noticed that by default the output was set to Audigy Stereo Output in Phonon setup (KMix->Audio Setup). This is totally **** setting by default stereo only and no hints that it can be changed (hidden deep behind settings) for such a widely used audio cards from Creative Labs.
How-To Solve this:
Select Audigy 2 ZS 5.1 or 7.1 as your output (according to number of speakers setup you have) and then:
To get access to these controls, close KMix (use right-click -> quit) and restart it by running KMIX_PULSEAUDIO_DISABLE=1 kmix in a Konsole terminal. To make this change permanent, add export KMIX_PULSEAUDIO_DISABLE=1 to your ~/.bashrc file.
This is ridiculous that it is not being implemented in Kmix by default!!! As per Gnome users I do not know as do not use it. In your case after step 1 alsamixer (select your output card there) might be of some help.
Ok, I am loosing my mind. Please help with the following:
Audigy 2 ZS with PulseAudio ON
How to get true 7.1 all time (I have selected SB Audigy as Sound Card and Analog Surround 7.1 Output as Profile)
Under Audio outputs (notifs, music, video, etc) now I have only SB Audigy Analog Surround 7.1 available, other are greyed out (Surround 5.1, Stereo, etc).
KMix - I want to see individual channels (front, side, rear, LFE (bass))
VLC - what I select in Audio so that VLC works well automatically with Stereo and 5.1/7.1 video files
This was all well in previous versions of openSUSE.
Ok, so I tried Disabling PulseAudio via Yast (didnot remove the packages), and the channels came back in KMix, but then the native apps of KDE, if I can call them so, like Kaffeine started playing 5.1 movie tracks in stereo! In VLC at the same time I had to choose manually 5.1, but then stereo tracks didn’t played.
So I tinkered my brain and put some logic and found a solution:
Enabled PulseAudio back
Selected Analog Surround 5.1 Output (Phonon->Speaker Setup), backend is GStreamer
Installed the VLC Pulse support package (vlc-aout-pulse)
Selected Pulse as the Output Module in VLC
Now Kaffeine plays 5.1 and stereo tracks properly as well as VLC now Automatically switches to 5.1 playback if the track in movie is 5.1 and also plays stereo tracks properly. Coool.
So, I guess with PulseAudio we will need all audio/video apps to have some kind of PulseAudio support (built-in/plug-in) or else we will face probs.
Now I need them all channels (master, front, centre, rear and LFE). Especially I need LFE (bass) which is too high by default, and I run alsamixer to minimise LFE channel, but as soon as I play a movie or music it is back to 100% automatically … cannot watch movie in late evenings w/o neighbours knocking my door.
Good effort, well done so far, I’m sure it will help other users.
You can control bass etc for VLC, through VLC’s Tools > Effects and Filters e.g. Graphic Equalizer. For Amarok, it’s Tools>Equalizer. Kaffeine is a bit thin on audio tools. Looks like you have to set up each application separately for sound. Unless someone else knows better?
Take a look at “pavucontrol” applet to see what that offers, as I’m not on 11.4 at this moment to check.
Actually there are some things that are missing from pavucontrol, and kmix. Pulseaudio simply doesn’t provide them When i use alsa, i can use smart 5.1. Meaning that the soundcard will output through all channels, and will use stereo expander to play 2.0 files through all 5.1 channels. With pulse audio i can not do that. Plus, there are a few apps, that sometimes cause problems when using pulseaudio. At least that happened for me. IMHO alsa is better. But that is just what works for me.
Unfortunately, the bug is back, KMix just showing empty tabs.
I don’t think deleting my KMix config files every day is normal, so I guess might file a bug report after all, but I will first check with a fresh account (no old kde-config files) whether it occurs there as well.
However, pavucontol nevertheless seems to work fine.
(BTW, Veromix as downloaded through the widget dialogues doesn’t work either.)
Thanks for that. Together with pavcontrol, it enabled me to get something working. Other problems that didn’t help were kradio installed but there was a problemwith it and somehow stopped all else working, and little hidden blocks in pavcontrol that had to be un-ticked. To me, audio is one of the main functions of a computer and without it life is drab. I thought that it would be good to share this experience so as to help others.
Thanks for the tip on deleting kmix config files in .kde4. that was the fix for me. I thought I was loosing my mind with the same “uselessness” of kmix. All the channels for my Audigy 2 zs are back on line with capture and playback working fine.
[QUOTE=STurtle;2305296]Aha, problem solved!
I just deleted all files containing “kmix” from the directories .kde and .kde4 and restartet KMix.
Now everything works perfectly: All sliders are there, no longer just empty tabs. KMix actually works nicely!
Thanks to all the replies above! I did not know that this should have worked nicely. I was close to just blamed it on KDE4 and abandon KMix.
