OpenSUSE Multimedia :: Disable A Sound Device In Phonon?
Jan 10, 2010
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...
I have two sound devices, an internal audio device on my motherboard and an external USB devices, which came with my headset. After upgrading to 11.4, the microphone on my headset ceased to work with my softphone. As it turned out, the softphone used the standard input device, which was defined in the Phonon tab in the KDE System Settings. Unfortunately, when I put the USB Device on top of the default input stack, it doesn't stay there. When I apply the changes and leave the Phonon tab or even enable "Show advanced devices " the stack always resets to its initial order. I was unable to find any kind of config file where Phonon saves this settings.
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.
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 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.
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
my computer is connected to my TV through HDMI using ATI HDMI output. I have written a small script to switch display from monitor to TV when a want to watch a DVD, but I didn't find how to switch sound from speakers to HDMI in command line. For the moment I have to open KDE system settings -> Multimedia and move sound devices by hand.
Is it possible to output one playback stream to multiple devices simultaneously with the current PulseAudio / Phonon setup? The PulseAudio mixer only has radio buttons to choose one device per playback stream. I believe the hardware is capable of this, since I remember doing that before we had PulseAudio. How can I duplicate an audio stream?
Here's one application scenario: I am travelling with my family, all crammed in small hotel room. My wife and me want to watch a movie on my laptop without waking up our kids. I just happen to have one analogue headphone available and one wireless USB headset with me. (Of course, the low tech solution is to bring an 3,5mm Y-cable to attach two analogue headsets, but I would really love to use the USB headset together with the analogue one.)
Another similar thing that bugs me is that my laptop's built-in speakers now always seem dead when an analogue headphone is plugged in. This is mostly what one wants, and before PulseAudio, one had to manually switch them off which was generally annoying. However, the downside is for example with notifications.
For example, before PulseAudio, I could configure Skype to always ring over the laptop's built-in speakers, regardless of whether the analogue headphones were plugged in. This is no longer possible, since PulseAudio does not distinguish between built-in speakers and built-in analogue port any more, while old Alsa did. So in my office, where some analogue headphones are plugged into the docking station, I never hear Skype ringing if I don't wear the headphones.
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 have a fresh install of Natty and i'm having some issues getting sound to work. My laptop has a built in sound card which works just fine. However, i also have a usb 5.1 sound card which isn't working at all. Both devices show up in 'Sound Preferences' but when i select the 5.1 device as the output device sound doesnt work. I ran the alsa-info.sh script and the output can be found here.
I have a 1TB external HDD which I use to store my music library of roughly 40 gigs. Therefore I would normally import music directly from it to my Rhythmbox library while keeping everything stored on the removable drive. In recent versions of Rhythmbox this is no longer needed as the application integrates my external HDD into the side pane and lists the music automatically. This is great although when closing Rhythmbox and reopening it, the drive has to be scanned all over again. This is a huge pain when it has to scan through 40+ gigs of music.
Therefore I would like this feature disabled and removed from my side pane. It is not needed and causes quite a large annoyance. Either I want it removed or the ability to keep the index of music from the drive in Rhyrhmbox at all times. Achieving this would be fantastic and would switch me back to Rhythmbox. recently I have been using Exaile which I love but rhythmbox not working bugs me.
this morning after a reboot I made a discover. Clicking on tabs, launching applications, and so on, make annoying and stupid sounds from my speakers. CLICK, BOP, BLAP! Who decided to turn these things on? I'm listening MUSIC, I don't wanna those stupid sounds bother me! Anyway, I was suddendly on System -> Preferences -> Sound and I choosed Sound Theme: NO SOUND. But those annoying sounds are already there. And there's no way to disable them! Is this a BUG or what? Is there something to do?
I also discovered another thing: clicking on items that are at RIGHT of my screen, the sound come from RIGHT. Clicking on center, they come from center. Right, right. So I realize that sounds are stereophonic. And really I can't understand why a software developer choosed to waste his time coding a piece of code to do this, instead of solving the hundred millions of bugs we're affected from YEARS.
I installed "Theocracy" on my 9.10 Karmic system. The installer asks for a sound device, dev/dsp is the default and I didn't change it. When I now try to start the game, I get the following error: Unable to open sound device: Device or resource busy Aborted Execution of /usr/games/theocracy_base/theocracy.real failed! What is the sound device when using PulseAudio on Karmic?
I don't have any sound in my external device (TV). I'm attempting to watch a movie on the VLC player but I can't seem to get the sound to work through my television speakers! They are coming out of my computer speakers just fine though.
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 know skype on Linux is crap but i have no choice as i now have only Ubuntu installed on this pc & I NEED SKYPE.so with the new version how do i select a particular sound device.i ask because skype only lets me select a specific sound 'platform' (pulseaudio).i have a motherboard with on-board sound & a USB voip phone (us robotics) and it the usb voip phone i want to use solely for skype
so is there something i can tell pulse audio that i want skype to ONLY use the usb phone or do i have to use the stupid sound preferences to change the system wide device to the usb phone which makes the whole thing a hindrance because i have no idea when someone calls me & when i have to quickly change the settings then turn off music then try to answer the call the person calling has gone!!!i like to have music playing in the background out of my hifi & the error noises come out of the usb phone as well when this is selected & to be honest it makes having a pc setup with multiple devices pointless and a hindrance
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 have got my headset connecting to the system using the BlueMan interface. When I first did this it gave me a error about not being able to put the sound on-top of 'pulseaudio'. Well this well about the last straw between me and Mr. 'PulseAudio', so away he went. I removed the demon via this instruction. [ubuntu] Safely Remove Pulseaudio?
I then tried connecting to my bluetooth headset again, no errors. But the bluetooth sound device does not show up in any mixer, or application. What else do I need to do to get this working again. I know my hardware is fine, it used to work in the previous version of Ubuntu and it all works on my wifes Windoze XP computer.
i am using ubuntu studio karmic and i have a digitech vx400 audio effects pedal which serves as an audio in/out midi in/out device via usb. i can sucessfully set it as the system sound device in system>preferences>sound for both input and output. but, when i play audio through it it only works for a few minutes before the sound stops completely. if i leave the system settings set to the internal sound card and configure jack audio connection kit to go to the usb device, i get the same results on the usb sound. a few minutes of playback at the most.i can restart sound with either "pulseaudio --kill && pulseaudio --start" or "alsactl init" in either situation. just requires restarting the programs. same results after restarting. i think this is alsa related as i have both the system sound and jack using the alsa driver, but i don't truly understand the relationship between pulseaudio and alsa.
when I plug headphones into my computer, sound comes out through both the headphones and the computer's speakers. Is there a way to disable the speakers when headphone are plugged in, or even disable them altogether?
