OpenSUSE Multimedia :: Phonon Doesn't Accept Standard Capture Device
Mar 22, 2011
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.
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...
In Ubuntu 9.10, I was successfully able to use my Pinnacle Dazzle DVC 100 (a cheap USB analog video capture device). I use it for backing up old video that is stored on tapes, and it isn't working with my current install of Ubuntu 10.04. When I plug the device in, it should be detected and the em28xx module should be loaded. This fails and /var/log/messages has the following:
Code: Sep 25 16:13:18 kernel: [1196215.111898] usb 2-2: new high speed USB device using ehci_hcd and address 20 Sep 25 16:13:18 kernel: [1196215.266097] usb 2-2: configuration #1 chosen from 1 choice
I need to capture from my webcam. It has a mic too.I can specify video input device as /dev/video0.I specified input audio device as /dev/dsp2 ( OSS device, corresponding to USB Webcam), Now VLC throws an error, "VLC is unable to open the MRL 'alsa:///dev/dsp2'. Check the log for details".Thinking it wants an alsa device, I specify device as /dev/snd/pcmC2D0c. (got it from kinfocenter and dolphin). Now again an error, "VLC is unable to open the MRL 'alsa:///dev/snd/pcmC2D0c'. Check the log for details.".I try with any device, the same error. I have added myself to audio device so that I can read/write to the mentioned devices.I see no way of switching VLC to use OSS. And I see no information (documentation on net) on it's expected device listing for audio.
there's one major issue left preventing Ubuntu from running flawlessly on my hine.Ubuntu doesn't recognize DVD-RWs once written on. The problem occurred with my old drive (LG GSA-H55N) as well with my new drive (Samsung SH-S222L).I'm using Sony DVD-RW (1x-2x speed) Ubuntu only recognizes blank DVD-RWsonce written on - no matter whether written by Brasero or Windows 7 - Ubuntu isn't showing any drive in Nautilus nor in Brasero after putting in the DVDtherefore I can't even erase themboth of the drives as well as the DVD-RWs are working perfectly fine on Windows 7 (erasing, writing)I managed to get all other things working by now. My system is close to perfection and this is the only remaining major issue.
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.
I have been trying to get tvtime or any tv package to work with my Pinnacle PCTV HD usb but I have not had success. I have correctly installed every driver imaginable. So, here is what it what it comes down to: When I open tvtime it says "cannot open capture device /dev/video0" and the screen is blue. But my usb PCTV HD stick is NOT /dev/video0 so the question is how can I get tvtime to look for the usb tv tuner rather than video0?
I've made a lot of progress getting my easycap 2.0 usb capture device to work with ubuntu 10.10. I've got the picture up any everything works great. But about a minute into the stream it just freezes, I need to go into "playback" and either pause then play, or click "next", it then refreshes and works again for another minute or so. I'd believe it if someone says faulty hardware because the easycap is cheap, but I don't think that's the case. Additionally, is there any way to set VLC so that when I open it, it automatically opens with my video capture device (/dev/video0) so that I don't have to go into the options and change it every time?
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.
My wifes computor crashed during an update with a message to fill in a report. It would not respond to any key presses. The computor has been running 11.3 since it was realeased without problems other than jerky video. The computor will not boot it asks for the password but does not accept it, Although I can see the Home folder it does not mount. I have tried testdisk but although it sees the partions it cannot acess them.
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'm making an attempt to install drivers for my easycap dc60 USB video capture device. Someone was good enough to make a driver project on sourceforge. Problem is I cannot get it compiled.
Code: Building make: Entering directory `/home/jan-bart/Download/easycap_dc60.0.4/src' make -C /usr/src/linux-headers-`uname -r` M=/home/jan-bart/Download/easycap_dc60.0.4/src modules make: Entering an unknown directory make: *** /usr/src/linux-headers-220.127.116.11-0.1-desktop: No such file or directory.

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 sound but my mic capture seems to be not working in skype or well anything else and I'm confused on what to do after searching. It's an integrated mic somewhere in my laptop. I enabled capture in Kmix but that didn't seem to do anything.
I am unable to capture sound from the sound card. I used to be able to do this with ease in SuSE 10.0 and 11.2. Now I have 11.4 and not only do I NOT have access to the sound card's channels (for base, treble, turning the mic on/off, and line in, Analog Capture Boost, etc) but now I can't seem to get at the settings for capturing sound coming from the sound card. I have tried using the Alsa mixer by way of the terminal and went to the Capture section and turned all of the settings all the way up. I didn't see any settings for Capture Boost as was available with 11.2's Alsa mixer GUI. Here's more of my info:
Isn't there ANY GUI sound mixer available that will give me access to all the channels I require? I not only record sound from my sound card, but I also use my mic at times for Skype and I like to be able to turn it off when not in use, rather than unplugging it all the time. I used to be able to do this with 11.2 and 10.0 and I really liked it that way. BTW, the plug for the mic is in the back of the computer and it's not convenient to have to plug/unplug it from there each time. For some apps, it's just a good thing to have all the sound settings done and in place before starting up the app. This I cannot do right now because of the changes to KMix and the Alsa GUI. I really really don't like this at all.
I recently installed openSUSE 11.4-64bit on my Gateway desktop, and I can't seem to get my mic work at all. The mic is built into my Microsoft LifeCam Cinema webcam and works fine when I boot into Windows. The mic will not record sound in krecord or lame and doesn't work during Skype sessions.
According to the literature for the device driver my the mic should be supported, and that is evidenced by the fact that the mic shows up as a capture device in in kmix. I have made this mic the master channel under capture devices and I have given it highest preference amongst my capture devices in both the Communications and Accessibility categories of kmix's Settings/Audio Setup.
There was a very similar case solved in January:
How I got my Sound Input working
I've done my best to implement these fixes, but half of it looks like gibberish to me. All I was really able to do was update my alsa software and generate this comprehensive alsa.conf (its long, so I'll wait to post it until asked).
I've had since updating to 11.4, and I gotta say: I've been really impressed so far.
I'm trying to capture my desktop screen and audio , before I used xvidcap but after upgrading my system I can not use it and also recordmydesktop anymore these APPs hanged when I try to use them.Now I try to use recorditnow via ffmpeg recorder interface , it work properly in recording the desktop but it does not record the sound , so I tried to add below options to its command -f alsa -ac 2 -i hw:0,0 but it just record sound at the beginning and just for 1 second. Also when I try to capture my desktop with ffmpeg directly from command line with below command I face with same problem!!! ffmpeg -f x11grab -s 1024X768 -r 30 -i :0.0 -f alsa -ac 2 -i hw:0,0 ~/out.mpg
Is there any way to prevent Flash from capturing all keyboard input? I'm really sick of not being able to ctrl+l or ctrl+tab just because I'm watching a video, and today a video froze in fullscreen mode and I couldn't even ctrl+f1 to any terminals or ctrl+backspace to kill KDE. It would be awesome to stop flash from grabbing certain key commands and pass them to the browser or OS instead.
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 am trying to record a test video with my built-in webcam, using Cheese. However, after I click "Start recording," the Cheese screen turns black, and Cheese seems to hang. I can click "Stop recording" sometimes -- then I get a split-second video clip. But mostly it just hangs until I force quit.
I'm on an Asus 900HA. I could record video clips on using eeebuntu and Cheese. Is there a setting I need to check?
I have been searching for an answer through most of the recent posts about sound issues but have not been able to find a solution. I am currently unable to capture sound from the "Line" input on my sound card. I do have sound and is working correctly for all applications and I do have P/A disabled (I'm not a huge fan of the sound quality with P/A enabled). I have checked and re-checked many settings but to no avail have not been able to capture sound. I'm sure I may be missing something or have not done something in order for this to work. I was using openSUSE 11.4 on a different pc and had no problems, unfortunately this is a different pc with a different sound card which is on-board so I am not entirely familiar with it yet.
It is a C-media CMI9880 which shows up as a Intel HDA (ICH6) and appears to be configured correctly.
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 just got a Motorola Atrix yesterday. Figured I could just use Banshee to manage the device in Ubuntu like I did with my prior IPhone.However, banshee doesn't seem to pick up the device. However, they dont' tell you what file to add it to. I did add those lines to /home/michael/.config/banshee-1/addin-db-001/config.xml which was the only xml file I could find for banshee. However, still doesn't work.
Does anyone have any experience getting the Atrix to work in banshee. Or does anyone know of another manager I would be able to use to manage music and video on Ubuntu. The only official way to do this is to use Windows Media Player or the motorola app both of which are Windows/Mac.
