Ubuntu Installation :: Phonon - No Sound After KDE 4.4 Upgrade
Feb 26, 2010
I was a happy user before I upgraded to KDE 4.4 in my Kubuntu 9.10. Basically I added ppa:kubuntu-ppa/backports to sources list as it's said here: [URL]. After I refreshed the packages list, there appeared equally big two lists with new packages, normal packages and so named as "blocked", if I remember correctly. Anyway, I selected normal ones and did update.
Now every boot I get this kind of warnings:
No sound in any application, except in Multimedia settings:
Here I hear music if I select a device and press Test.
I decided to do another test, I installed Kubuntu 9.10 in VMware and upgraded to KDE 4.4, the same problem. I don't want to reinstall the whole system.
I recently had a brain cramp and told Phonon to forget my sound card(s). I have an on-board card and I have installed an old-school Sound Blaster CT-4832. I have followed the steps listed in the comprehensive sound trouble shooting, and still no luck!
Code: gentle@Desktop:~$ aplay -l **** List of PLAYBACK Hardware Devices **** card 0: NVidia [HDA NVidia], device 0: ALC888 Analog [ALC888 Analog] Subdevices: 1/1 Subdevice #0: subdevice #0
Sound works great for non kde programs such as firefox and vlc. Amarok and dragon player however refuse to play with sound. Sound doesn't work either when testing it in the 'Multimedia' section. I have no pulseaudio installed. Any ideas where I can look for possible solutions? code...
I have two sound cards active on this machine and they both work fine. However I would like to blacklist one card from being used for audio capture in KDE, because I am already using it outside of KDE for timed recording. The problem is that when I start amarok while timed recording is going on, it attempts to probe the card and this causes the recording to abort.
In Configure desktop > Multimedia, I can see the two cards. I can alter the priority but the Remove button is greyed out. So I can't remove a card from phonon.
Searching around for where phonon stores its configuration led me to ~/.config/kde.org/libphonon.conf. This certainly looks like the info I was trying to edit, but it's encoded in some way code...
Play a song in Amarok and then press the space bar to pause. Press the space bar again to resume and Amarok starts playing again with the status bar moving and the timer counting down, but no sound. If I move to the next song, sound starts working again. Or if I double click on a different song, sound works. If I use the xine backend, the problem goes away. I'm using Amarok-2.4 and KDE 4.6.1.
Have a couple of very annoying problems. I recently did a re-install of Kubuntu Maverick on my HTPC/fileserver box.It has an onboard (Realtek?) audio card, recognized as... I think, ALC888... Yeah, not sure, KInfoCenter lists a bunch:ALSA Sequencer DeviceUSB 2881 Device ALSA Control Device (my DVB-T stick)ALSA Timer Device
HDA Intel ALSA hardware specific Device ALC888 Analog ALSA Capture Device ALC888 Analog ALSA Capture Device
Upgraded from 10.04 to 10.10 using standard Update Manager procedure. Now I get a sound (thump) in my speakers for almost every button click. The sound theme in System / Preferences / Sound is "No sounds". I would like to completely disable any "activity" sounds from the OS, but nothing works.
I know that beta is unstable, but I didn't expect my sound to quit working. Especially because it was an upgrade and not a clean install. On another thread I saw that "pulseaudio -k" but it did nothing for me. I don't even know if my sound card is being detected.
The sound is an onboard Realtek AC97 chip on my motherboard. It worked absolutely fine on my 9.04 Jaunty setup. My machine is dual boot with Windows XP and the sound is fine on XP, so it's not a hardware issue. Karmic seems to think there is no audio device present at all, which is obviously not the case.This is an AMD 64-bit machine running the x64 edition, although I doubt that has anything to with the problem. Everthing else in the installation went perfectly and the GNOME desktop seems significantly quicker too.
I upgraded successfully last night from Hardy Heron to Lucid Lynx, but have no sound now. After searching around I can see that this is a fairly common problem. But none of the proposed solutions that work for other people have yet worked for me.
If I type 'alsamixer' at the command line, everything looks fine. There are no 'MM's indicating something being muted. I tried removing and reinstalling alsamixer and pulseaudio with no success. Edited lines 45 and 46 of /etc/pulse/default.pa with no luck.
Sound does not work in my newly installed 10.04 (why I upgraded I will never know - I'm back to the same slowness problems with my ATI Radeon card as well). This time, however, I seemingly can't use my previous lazy approach of just switching on Digital support - it still won't work. Any suggestions - I'm really bad with Linux - and I have tried a couple of suggestions (I haven't recompiled alsa) - none of it will work.
Below is the output from an aplay -l command...
I gots to have my music - I might as well be using Windows if I have no music.
I recently upgraded from 9.04 to 9.10 and the sound on my machine no longer works. I was previously using the OSS for sound. I'd like the sound solution that requires the minimal effort and I don't necessarily need to run OSS again. Ubuntu is installed on a Dell Optiplex 960.
I installed OSSv4 replacing the default ALSA and everything worked just fine with some workarounds... until I upgraded to Lucid Lynx. Now apps like Totem and Rhythmbox which use the gstreamer framework have no sound. Does anybody know why?
Last night I upgraded to 10.10 RC, and everything went smooth. A lot of problems were resolved in the upgrade, but unfortunately I got two new problems.1. No Sounds at all. My speakers hum, and I can control the level of the hum/mute with Kmix, but no sounds makes it through. So Kmix is controlling the hardware, but somewhere the sounds isn't making it there.2. No system settings. The system settings panel appears in the app tray when I run it, but after a minute of thinking (and not opening) it disappears.
Code: :~$ sudo aplay -l **** List of PLAYBACK Hardware Devices ****
After upgrade, I noticed that audio is full of static. It sounds as if one of the sliders has been pushed too far and it's blowing out the sound. I've tried it across several applications(rhythmbox, browser), and all audio is like this.
I've looked at the audio settings on the dock panel, but nothing seems amiss(and in fact doesn't leave much room for manipulation).
Is there another audio management system I should be using to try to resolve this or might there be something wrong with the upgrade process?
I've just done an upgrade after noticing the Update manager thingee at the bottom of the screen. I was listening to my music when I noticed it.
I did the Restart now after upgrading. Now I have no sound at all. Checked headphones were turned up which they were. Checked sound settings and found there were no Devices in Hardware and Input and a Dummy Output (stereo) listed in Output. I would have thought that my onboard sound would have shown up as well as the sound bits on my HDMI card - not that I've ever managed to get sound out of my telly via the HDMI cable. (I do have Alsa sound installed).
I upgraded my ubuntu installation from 10.04 to 10.10, now surround sound (5.1) does not work in xbmc, or in another player such as vlc. Only the front two speakers work. I noticed pulseaudio and alsa are installed. I thought i removed pulseaudio once before but cant really remember. In the sound configuration preferences thing (prefs >> sound), i have hdmi output selected (hdmi goes from the HTPC to the amplifier). It only plays audio in 2.0 instead of 5.1. I tried selecting the analog 5.1 sound option, but none of the test sounds work. However i noticed vlc still played movies with audio, but only stero no 5.1.
Previous to the upgrade, i had 5.1 working fine in xbmc, never bothered to check vlc since it was all good. Also, when i go into alsamixer, it does not show any rear speakers, it just shows a front speaker and a bunch of other stuff, like headphones. I'm not sure what other output you guys need, but let me know and i'll get it. Here is the alsa-info.sh output for my HTPC: [Code]..... Another note, after i reinstalled pulseaudio the first time, vlc fails to display a 5.1 movie and still plays tero output.
I upgraded a working Fedora 9 installation to Fedora 10 using the installation DVD. Sound works for root but not for other users. All of the pulse audio RPMs are installed. This appears to be a permission issue as it works for root. My user is a member of the 3 pulse Groups.
I am using Ubuntu 10.04 on a dual-boot system with Windows 7. Yesterday I upgraded from 2.6.32-23 to 2.6.32-24. After that, pressing the shutdown button and selecting shutdown or restart (whether on the login page or after I've logged in) will only bring me back to the login page. I can shutdown or restart if I do sudo shutdown now, but I'd prefer to use the GUI. Also, there is no sound now (not a big deal, but still not good). And I can't access my storage partition (not the windows7 partition, but a third ntfs partition with data on it). I get the error message that I am unauthorized to mount. I have the only account on this computer, so I should be authorized. This one is a HUGE problem for me, because I need to be able to access my data for work. None of these were problems before the upgrade.
Oh yeah, and quickstart is not enabled. Also, if I go to Power Management, and try to alter what to do when Power Button is pressed, my only option is Ask Me. I know these have been problems/solutions to the shutdown/restart problem in the past.
Excited at seeing the new features in 10.04, I clicked the Upgrade button tonight. I am now really regretting it! Problems:
1. My screen resolution should be 1280x1024 but the System>Preferences>Monitors control panel only shows 1024x768.
I think I have onboard Realtek graphics. Do I need to install proprietary drivers? Everything worked fine out of the box with 9.10!
2. The sound isn't working. Again I think I have onboard Realtek sound, and again it used to work fine without any intervention from me...
3. Although on first startup wireless networking was working fine, I restarted to see if that would solve the display issue, and wireless networking stopped working too!
I have an RaLink wireless card.
When I used Grub to choose 188.8.131.52, I got some error messages at startup (e.g. mount couldn't mount /dev), but then it did eventually start up and the sound and wireless networking are working again. But the resolution is still not fixed. It is now offering 1152x864, which it didn't previously, but no 1280x1024 (my screen's native resolution).
In Karmic's Amarok 2.2, when you pause and then play, the sound usually stutters a few times before it starts playing smoothly. I originally thought this was a pulseaudio issue, as stuttering problems have been reported with pulse, but that wouldn't explain why sound is fine in mplayer, audacious, vlc, dragon player, and virtualbox. Only amarok has this problem. I found the cause of the problem: phonon-backend-xine. These steps will get rid of the stuttering problem:
1. Install phonon-backend-mplayer. You can get it from Rog131's PPA: [URL]
2. In Multimedia and Sound Configuration, which you can reach through amarok's Playback settings, on the Backend tab, click the arrows to move mplayer up above xine.
3. Quit and restart amarok.
There are some tradeoffs for good sound. Amarok seems to have some bugs when the sound backend is not xine, and bookmarks and OSD are broken when this backend is playing the sound. When you quit Amarok, it can't bookmark your place so it doesn't restart from where you last were, and after the track changes once, the OSD when you hover over the tray icon only says "Amarok - No track playing." You have to open Amarok to find that info. Are there any settings I can access for phonon-backend-xine that could fix the stuttering issue? The problems with the mplayer backend are minor compared with xine's bad sound, but I would like nice sound, OSD, and bookmarking.
I have an Asus EEPC that I use in my classroom whenever I want to show a movie. I normally keep all of my educational videos as ISOs, and then simply move one over to the netbook when needed. I normally use VLC for playback. With the latest upgrade, however, I'm having a few difficulties. No matter what DVD I choose to show with VLC, the audio stream will randomly drop every 10 minutes or so whenever I am using KDE as my desktop environment. In order to re-enable the audio stream, I have to either completely stop playback OR reconfigure the audio output in VLC.
(It does not matter if I change it right back to what it was, I will get audio for another 10 minutes or so). I've also noticed that if I pause playback, sometimes the audio will not re-enable when unpaused. Strangely, however, I do not have this behavior at all when I'm using Gnome as the desktop environment. I get seamless audiovisual playback and never have to fiddle with the audio. Is this a documented problem in Phonon somewhere? How I might better backtrace what's going on?
I've been trying to install a development version of kde 4 and when i attempt to install kdelibs it tells me that it can't find the phonon libraries. Does anyone know what the trouble might be? I'm using Debian Sid.
I have experienced that Phonon will crash occasionally when I advance to the next track in Amarok. After Phonon crashes, Amarok can't play sound. The only remedy appears to be restarting.
I would like to avoid the crashing. I have heard that Phonon and PulseAudio do not work well together. I would like to know how to disable PulseAudio when using Amarok. Any hints?
I am using the Xine backend in Amarok. In the Config Phonon window, I have configured Phonon's hardware preferences to work directly with the sound hardware on the MoBo first. I have deprioritized PulseAudio to the bottom of the hardware list. Unfortunately the "remove" button is grayed out in the Phonon config window.
I am running Ubuntu 9.10 - the Karmic Koala w/ Gnome so I don't want to uninstall PulseAudio.
I'm using F11, KDE4. I have uninstalled Pulseaudio as it's unusable for my configuration (2 souncards, one of them a M Audio Delta 66). In order to not have Phonon blocking my M Audio Delta 66 card I need to use DMix. The built in ALSA dmix support doesn't show up in Phonon (System Settings -> Multimedia -> Device Preference) but I found out after some research how to add your own dmixer in the ~/.asoundrc file. Here are a few links:
It might depend on the way it tries to access this device. When you hover the "DMixer" device it displays it will try the following devices: 1. ALSA: dmixer I think it should rather be ALSA: plug:dmixer But I can't figure out where you are able to configure this, does anyone know? I also wonder how I can remove the Pulseaudio entry in phonon. This is not important but still though PA is uninstalled. There is a Remove button but it's always disabled.
I have installed smplayer, and configured it to use the code...
Kaffeine (and dolphin's video preview) seem to use phonon's xine backend, and I can't find out what video output it uses. I'm guessing its plain old xv as it seems accelerated but turnes into a blue square when I move the window.
How do I tell the xine backend to use the same vo as smplayer?
OS 11.2 64 bit, KDE 4.4.4 (Factory)
(ps: I have a 'legacy' ATI graphics chip, xpress 200M working with the opensource radeon driver, which is brilliant btw).
So I have made an interesting Discovery with regards to using KDE4 Kaffeine version 1 and Dolby Digital 5.1. The basic problem seems that there is no way to configure the Phonon xine Backend in KDE 4 for use with Kaffeine version 1. There is however, a xine-config file located at:
There appears to be no GUI way to change the default xine configuration (for use with KDE 4 applications) and while you can do so manually, the options seem bewildering, at least to me.
When you run xine-ui or Kaffeine/KDE3 there is an option to adjust the xine audio configuration using a GUI. Any changes made here are ignored by KDE 4 applications. As luck would have it you can copy the old xine configuration (adjusted by Kaffeine/KDE3) over the new one for Kaffeine in KDE4. The old text file configuration is located at:
If you were to use the old Kaffeine/KDE3 to adjust your xine audio configuration and then copy this file to the Kaffeine Version 1 KDE4 location, those changes should be used by the new version 1 Kaffeine in KDE 4. After Kaffeine/KDE3 audio settings work as you desire, open up a terminal session and make the following file copy. You must overwrite or rename the old configuration file for backup.
