No sound in KDE4

I can not get the sound working in KDE4 apps (Amarok 2, Juk).
If I enable the Gstreamer plugin I get a popup telling me that the sound system didn't work. But if I choose Xine Juk acts as normal and starts playing the track - but I can't hear anything. If I start up Xine while Juk is playing I hear whatever Xine is playing, but still nothing from Juk.
I upgraded KDE today and I'm using the latest version from pacman (4.1.0). I'd appreciate if anyone could help me fix this as I really like KDE4 this far.

I tried configuring phonon with qtconfig today, and qtconfig just says that "not available" on phonon version and gstreamer version. Everything is greyed out and at the bottom it says that the Phonon GStreamer backend is not available.
`pacman -Qs phonon gstreamer' shows this:
local/phonon 4.2.0-1
KDE Phonon
local/gstreamer0.10 0.10.20-1
GStreamer Multimedia Framework
local/gstreamer0.10-base 0.10.20-1
GStreamer Multimedia Framework Base plugin libraries
local/gstreamer0.10-base-plugins 0.10.20-1 (gstreamer0.10-plugins)
GStreamer Multimedia Framework Base Plugins (gst-plugins-base)
local/gstreamer0.10-ffmpeg 0.10.4-1 (gstreamer0.10-plugins)
Gstreamer FFMpeg Plugin
So everything that's needed should be installed.
I'm very confused

Online videos have working sound. It is the desktop apps which are silent. Please tell me further ways to diagnose the problem.
[Off-topic rant] My last install was an year ago and went like a dream. This time I had issues with networking, pacman, xorg and sound. Kdm refuses to log me every even attempt, to which I still have to find a solution. KDEmod4 has a lot of app crashes. Opera is as stable as alpha

Kde4: sound problems

Hello,
I recognize 2 sound problems with kde4 here: The kde startsound is not fully played (cut after 2-3 seconds) and in general the sound is very quiet although the mixer controls are at the top, e. g. when playing an internet video.

I think the login in sound cuts out if you are logging into a session and another program steals sound focus. I only say this because the same thing happens on my desktop and it happens as pidgin and my systray apps start coming up.
On your mixer applet see what the label is, the default on mine after I upgraded was PCM I would move that up to about 80 and then right click on the applet itself and choose Select Master Channel
I was able to choose Front which seems to another way of saying main or master, as once I chose that the volume levels were more satisfactory.

KDE4: Crappy system sounds

I'm running KDE4 from the normal repos (not KDEmod). My system sounds - e.g. the start-up melody - sound like they would have very bad sound quality (like played from an old vinyl record). Codecs are installed. Every sound file on my computer sounds normal. Even when I go to /usr/share/sounds and play the sounds with e.g. vlc, they sound normal.
Some guy on IRC told me the bitrate settings might be wrong, but he didn't know, where to configure this in KDE4.
Does anyone have a solution for this?

i recently had a gstreamer issue that i solved today as well. run a pacman -Ss gstreamer0.10 to see which packages you have installed. you might need to install the gstreamer0.10-plugins group of packages, as i did.
this might be completely different from what i went through, since i'm not using phonon or kde, but it's worth a shot. worst case scenario is you uninstall the extra packages afterwards.
another option to try (which didn't help me, but was a solution for SOMEONE i found through my searches) was to compile and reinstall a fresh version of the gstreamer0.10 package. abs makes it so simple to do, it's also worth trying.

KDE4.1: Disable System Sounds

Hey all
I'm using the KDE4.1 daily svn builds. Does anyone know how to disable ALL system sounds?

Oh, this would be like the first thing I want to know about kde4.1 I hate those sounds, they are annoying at best. But I have failed to find the way to turn them off.

[SOLVED][KDE4]Only system sounds will play

I'm not sure if this belongs here or in the DE section, so please move it if you see fit.
I'm having a bit of a tricky issue with KDE, all the system sounds will play, but nothing else. I'm currently using the gstreamer phonon backend with ALSA. I've seen some forum posts from the gentoo wiki with similar problems but it seems it was just a mixed mess of deleting .folders and other configuration files. I've also tried to use the VLC phonon backend but to no avail either. I'm wondering if anyone else has this problem and has a coherent solution.
So far I've tested playing audio files in VLC and videos on youtube. My alsa device is fully configured and will play audio, just not output from programs that are not part of the plasma environment. I have also looked to the wiki for a solution but it only seems like it has solutions for audio conflict problems, which is all sorted out for me.

[SOLVED?] KDE4: Removed sound devices popup appears when sfx is played

edit: Marked as solved because this problem hasn't occurred for a while. Will be re-opened if it occurs again.
When doing something that triggers a KDE desktop sound effect, such as emptying the trash or searching for something in Kate, this popup appears:
This happens only once per boot. After closing the window it doesn't reappear until the system is rebooted. All sounds work well, without any problems. ALSA is used, no Pulseaudio or other sound servers.
Any ideas what to do? Should I click "yes" when it wants to "forget" sound devices? There are multiple reports about this problem at the KDE bug tracker but I'm not sure if this is a bug or just a configuration error.

There were some duplicate devices listed in the Phonon settings panel so I let it forget those. Now it only complains about one device.
This doesn't have duplicates and it won't go away even if I let it forget it. It appears again after reboot.

The Sorry State of Sound In Linux

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
READ: http://insanecoding.blogspot.com/2007/0 … linux.html
I've only discovered this because of an ALSA bug was making my life miserable. That article was written about a month or two before OSS4 (Open Sound System v4) was released under GPL and CDDL. This past January, it was released under BSD as well. Unfortunately for the developer, he does not understand open source very well. He is now reporting that his revenue went significantly down..
OSS4 does not equal to the crap OSS in Linux 2.4 kernels. Even OSS3 != OSS3 in former linux kernels. He was neglecting the open source version in favour of the commercial one. Instead of improving it, someone forked it. And, the fork became popular. Unfortunately, the original author had no interest in working on the fork. So, he only focused on the commercial version. Now, many years later, the commercial version is fully open source. There is no more commercial version.
I've tried it, and I really like it. Music sounds much better than on ALSA. For example, screaming in alternative rock is more legible. It's like enabling "enhance voice" in a phone. It supports higher PCM values without noise.
The mixer (vmix) is capable of 18 channels. It can also do per application volume control (like PulseAudio).
It totally makes sense that OSS gets back into the kernel because it works on almost every UNIX and UNIX-like system (except OS X). ALSA only works on Linux, and according to that article, developers still prefer the OSS API, even on ALSA. However, the ALSA OSS API is lacking according to an ALSA developer. I can confirm that the comment on the ALSA OSS Emulation API working better than the ALSA API. XMMS with ALSA enabled freezes my system. XMMS with OSS enabled on ALSA does not.
It worked without any configuration besides muting some channels to kill the noise.
THE BAD
ossmix and ossxmix are totally unusable because they do not name the channels properly. ossxmix uses 100% CPU if Compiz is enabled. Version 4.1 will fix this.
I had to figure out WTF ossxmix.codec1.connector.jack14.jack 54:54 means. Sane names need to be added to the jacks such as "mater, front, input, auxiliary, microphone, etc.."
It's best to use ossxmix (GTK+ mixer) and playing with all the jacks to figure out what each one does.
One interesting control is how OSS4 should behave (Fast, Medium High, Professional, etc.). It's probably a latency control. ossxmix is a demo app on how you can control the mixer from GTK. It needs to be made usable.
If you use Media Player Daemon, VLC, and MPlayer, OSS4 works beautifully. They use OSS directly. Others have problems.
Totem does not play sound. Totem-Xine uses 100% CPU (Xine-UI works with low CPU usage).
In terminal I noticed some output from oss mixer control saying it received bad arguments. OSS4 is backwards compatible with OSS3, but xine-lib may be using the API badly.
The progress bar (seeker) in GStreamer based applications (Rhythmbox, Banshee) does not work if you use vmix, or it may work, but it will be unsure of the length of a song. You will see it constantly adjusting a few seconds up or down. By the middle of the song, the length reporting generally stabilises. You have to enable softoss (the old mixer). vmix and Gstreamer behave very badly. The Gstreamer developer responsible for OSS claims that it does on his system. Though, he is most likely using the trunk version.
You have to apply this patched gstreamer to make volume control in GNOME work.
While the progress bar problem is fixed with softoss, volume control does not work, even with the patched GStreamer. It only works with vmix. System > Preferences > Sound lists nothing under "Default Mixer Tracks".
Sound does not work in KDE4 at all. While Phonon is based on Xine, which has OSS support, it queries HAL, which does not support OSS4 yet. Therefore, it thinks that there is no sound card.
As for KDE 3.5.9. Amarok works, Noatun works, and anything based on MPlayer should work. KMIX does not work. Same in KDE4.
DOWNLOAD IT (Popular Distributions Linux and Unix Distributions)
Gentoo ebuild
Arch Linux
The Arch Linux wiki has a good article. Read it.
A Ubuntu user has published an install guide as well.
Check Configuring Applications for OSSv4 after you install it.
Overall, I think it's a million times better than ALSA. It's cross platform, and it's stable. It was released a year ago on 15th of March 2007. Since he does not have a marketing department, no one has heard of it.

Hmm, so it's a choice - have to enable effects and use an older mixer, or put up with a 'stuck' progress bar... Well, as I said, I use MOC, and I'm happy with my mixer setup so far, so I'll stick to what I've got.
I can't believe I finally have my headphones working, or external speakers, should I so wish - and what with the ATI divers *finally* providing tear-free video, it's like it's my birthday
Since you mentioned ATI and went offtopic, can you pastebin your ATI xorg? It works fine for me, but If I enable compiz, i get flickering video and slow scrolling. So, I'm stuck with the open source driver, which uses a lot more CPU when I play video.
I can also confirm what the article said about the ALSA OSS emulation. It does work better than ALSA with the ALSA API. xmms with ALSA enabled freezes my sytem. xmms with OSS enabled running ALSA does not. I'm tired of this bollocks. We have to mount a campaign to get OSS back into the kernel.
Anyway, this is my OSS output.

[SOLVED] No sound playback in Cinelerra

I am using Cinelerra-cv ( the "pacman -S cinelerra-cv" version) and when I try to play a video in the timeline the audio does not play and I get the following error:
AudioOSS::open_output: No such file or directory
The sound works in other applications just fine and I had this same exact problem in Ubuntu 11.04. So do I need to install or configure something? or is this just a bug in Cinelerra?

karol wrote: Maybe you need to install or configure OSS
On my system I am using KDE4 which I believe requires PulseAudio and I have found out that OSS and PulseAudio conflict with each other.
However I did some research and I found a solution on the PulseAudio article of the ArchWiki to make OSS programs work with PulseAudio.
As mentioned in the Wiki I installed ossp:
pacman -S ossp
after install, I ran the ossp daemon:
rc.d start osspd
then I ran Cinelerra using the padsp command:
padsp cinelerra
and the sound plays in Cinelerra!
So as it turns out I just needed to install or configure somthing.

[Solved] Can't get sound to work proper

Hey
I use KDE4 with KMix. I have 5.1 Optical sound.
When I enter Audio Setup in KMix and test the "hw: 0,1" option I get playback.
But I haven't gottten any sound except that. Tried a video in MPlayer and Youtube video in Firefox.
I'm still abit new to Arch and linux.
Also tried adding
ctl.equal {
type equal;
pcm.plugequal {
type equal;
# Modify the line below if you do not
# want to use sound card 0.
#slave.pcm "plughw:0,0";
#by default we want to play from more sources at time:
slave.pcm "plug:dmix";
#pcm.equal {
# Or if you want the equalizer to be your
# default soundcard comment the following
# line and uncomment the above line.
pcm.!default {
type plug;
slave.pcm plugequal;
pcm.eq {
type ladspa
# The output from the EQ can either go direct to a hardware device
# (if you have a hardware mixer, e.g. SBLive/Audigy) or it can go
# to the software mixer shown here.
#slave.pcm "plughw:0,0"
slave.pcm "plug:dmix"
# Sometimes you may need to specify the path to the plugins,
# especially if you have just installed them. Once you have logged

Syth wrote:Well as I said. Sounds like KDE startup sound and such works. Just can't get any sound out of mPlayer and youtube.
Did what you said. PCM was the only one muted.
Oddly, I recently started having the opposite problem. KDE startup and other systems sounds have stopped playing. All my other sound (mplayer, flash, etc) work fine. I can play the startup sound fine when opening it via dolphin. It just doesn't play on startup, or any other system sound. I know this happened after a recent update but I am not sure what or when caused it. Startup sound isn't that important to me but fixing it is. No luck so far.

[SOLVED] LXDE: no sound in thunderbird

Just cleaned up my laptop by removing KDE, Gnome, and every other DE/WM I've managed to collect over the years. Now I'm running LXDE, and am so far delighted with how far it's come since the last time I tried it (several years ago).
Anyway, I've got everything working just how I want it, except for Thunderbird/Lightning notification sounds. They just don't play. I installed pulseaudio and sound from other GTK apps (pidgin) works just fine, as does youtube, etc.
I've read a few TBird bug reports that hinted it relied of ESD for sound. I only found ESD in AUR, though:
aur/esound 0.2.41-3 (285)
Enlightened Sound Daemon
Previously I was using KDE4 and Thunderbird sounds worked, I assume via ARTS.
Anyone have any idea?

that problem is likely a bug in PULSEAUDIO, as pulseaudio is SUPPOSED to be a drop-in replacement for ESD.
In KDE4 / QT Phonon takes care of the multimedia, and normally apps don't goto pulseaudio directly.
Output is send to phonon, which then sends it to the chosen output device, which CAN be pulseaudio.

No Sound with Onboard Intel Sound Card - http://wiki.archlinux.org/index.php/ALSA
Last edited by treefiddy (2009-05-06 20:04:07)

OMFG you are awesome, who would've even tried that!!!!
Thank you!
this information is literally nowhere else in the entire interwebs!!
I was going insane, I also have a Gateway P-6860FX running THE best linux distro out there, Archlinux of course!
I had it partially working with:
options snd_hda_intel model=notebook
which I got from http://help.ubuntu.com/community/SoundTroubleshooting
but my speakers never worked until I found your post, so I was using a craptastic USB soundcard I found in my garage.
While I'm at it lemme post my ".asoundrc" which took me about a week of research to construct.
I had to do it this way because if I played ANY sound through any program while firefox was open on a page containing flash, all of the sound system was completely lost and mute until I restarted Firefox and/or the X session. Meaning no amarok while on the net if I planned on seeing any flash videos during my entire surfing session.
This configuration should work with ANY sound card that lacks a hardware mixer and uses dmix with the following effects:
1. OSS, AOSS and ALSA sound apps/games can share audio output without distortion
2. A new virtual soundcard called "My Soundcard with extra Volume Control" will show up under kde4 that feeds into the software mixer
3. A new volume control will show up in all your alsamixer apps that allows you to control the volume of all ALSA apps, OSS apps, while still mixed are only affected by the master volume.
~/.asoundrc
#/etc/asound.conf start:
#pcm.!default pcm.softvolPhonon
pcm.!default {
type plug
slave.pcm "softvolPhonon"
#list card for phonon
pcm.softvolPhonon {
type softvol
slave.pcm "dmixer"
control {
name "Phonon"
card 0
min_dB -51.0
max_dB 0.0
resolution 100
hint {
show on
description "My Soundcard with extra Volume Control"
#endofphonon
pcm.dsp0 {
type plug
slave.pcm "softvolPhonon"
pcm.dmixer {
type dmix
ipc_key 1024
slave {
pcm "hw:0,0"
period_time 0
period_size 1024
buffer_size 8192
rate 48000 #many new cards are 48000 only
bindings {
0 0
1 1
ctl.dmixer {
type hw
card 0
device 0
#end.
if you have more than one sound card and want to use the second, just change "hw:0,0" part to "hw:1,0" and "card 0" to "card 1", this has the affect of changing the default sound card systemwide, without having to mess with each program's settings.

Flash plugin with firefox 3, no sound [SOLVED]

Good morning.
I would like to report a problem that I have with the flashplugin in firefox. I installed it using the nspluginwrapper-flash 9.0.124.0-1 in AUR. It works, but I get no sound at all. I nstalled the suggested lib32-alsa-lib package, but nothing changed. When I launch firefox I get the following errors:

It tries to load the 32 bit flash plugin because it is in /usr/lib/mozilla, but I have the wrapped version in $HOME/.mozilla/plugins. The relevant error seems to be the no soundwrapper.
You might notice that I am running KDE4 svn but I don't think this has to do with the problem.
Did anyone have a similar problem?

I would check the installation of nspluginwrapper and nspluginwrapper-flash because lib32-alsa-lib is listed as a dependency in the nspluginwrapper-flash PKGBUILD and so should not have to be installed manually. Also, did you run "nspluginwrapper -v -a -i" as your user and not as root after installation?

No sound in SOME players [SOLVED]

Hi,
I can hear sound with audacious & mplayer and in all browsers/flash.
I hear NOTHING with vlc and kaffeine though.
What would be the best way to find out why?

For the record:
I had to uncomment the following section:
#audio.driver:auto
and use:
audio.driver:alsa
instead in:
~/.kde4/share/apps/kaffeine/xine-config

[SOLVED] Audio dropouts with USB sound card

Hi! Recently I bought an external USB sound card (Music Fidelity V-DAC). If I plug in the USB cable the sound device is recognized by Phonon in KDE4 (kdemod).
If I play an audio file in Amarok (or VLC) the audio is indeed redirected to the USB sound card and played correctly. However, if I use my USB mouse, or USB keyboard dropouts are occurring in the audio signal. It seems that other USB devices are interfering with my USB sound card.
More details:
Arch Linux with kernel 2.6.33 and kdemod 4. Phonon backend is Xine. I also tried gstreamer, but this crashes Amarok/
$ cat /proc/asound/cards

I also tried an Ubuntu (9.10) live CD. Using ALSA or Pulseaudio a clean audio signal without dropouts is produced.
I wonder if someone can help me with this problem, or point me to more information. Thanks!

Thanks for your suggestion. I added the following line to my /etc/modprobe.d/modprobe.conf file:
options snd-usb-audio enable_msi=1
After a reboot the problem still persists. I also tried another suggestion from this forum:
options snd-usb-audio nrpacks=1
This doesn't work either. I tried to change settings in /etc/security/limits.conf, which looks like this:
@audio - rtprio 99
@audio - nice -10
@audio - memlock 250000
The USB sound card doesn't share a IRQ with another USB devices, as can be seen here:

Any other suggestions?
I even tried to disable the internal sound card by blacklisting it:
blacklist snd-hda-intel
.. but still no success
