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 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.
When I installed my 64 bit system of Ubuntu 10.04 the sound worked very well and I were very happy. The problem started however when I installed Skype which uses pulseaudio. As soon as I start skype (or any other application that uses pulse, HoN for example) the applications sound output or input does not work at all. If I have pulseaudio started in some way, applications that I suppose do not use it like spotify or flash player stops to produce sounds. And when I type "pulseaudio" in the terminal it gives me this:
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.
Every time I boot my machine, some of the playback values in alsamixer are set to 0 and are muted, so I have no sound.
The thing is, I have tried setting these to normal levels and then run sudo alsactl store. Then, if I run sudo alsactl restore after I reboot, the sound comes back up. However, if I have alsactl restore in /etc/rc.local, it doesn't work: I still get muted sound when I reboot. I have to run sudo alsactl restore manually each time.
I have already checked whether /etc/rc.local runs at startup, and it does. Also, I know that /var/lib/alsa/asound.state contains the correct values, because when I run sudo alsactl restore, the sound returns to normal levels. So what remains is either alsactl restore doesn't work in /etc/rc/local, or something runs after it and mutes the sound.
About two weeks ago I enabled KDE factory repo to get the latest KDE 4.4. Everything was fine until a recent update, which caused sound working only in some applications. Sound now works when tried in System Settings and Yast->Sound, but it does not work in Firefox, VLC, Skype, and so on.
I've been running Maverick 64bit fine on my Dell M1330 laptop until a couple of days ago. After the latest updates (I guess to kernel 2.6.35-24-generic), sound stopped working properly. The sound indicator applet tells me that the sound system is not responding. The login sound doesn't play anymore.
On the other hand Rhythmbox plays and I can hear the music. I can adjust Rhythmbox volume but not the global volume (as neither the sound indicator applet nor the multimedia volume keys on my laptop work).
Code: $alsamixer it works flawless. Here is what I get if I try to run pulseaudio from the terminal
Code: $ pulseaudio E: module-ladspa-sink.c: Master sink not found E: module.c: Failed to load module "module-ladspa-sink" (argument: "sink_name=ladspa_output.mbeq_1197.mbeq
I just installed skype 2.1 beta 2 (the deb file) from the skype website, but the only option I see under Sound Devices -> Recording is "PulseAudio Server (local)" This doesn't work for me, as the skype test calls don't actually record anything I say. I use skype a lot and FINALLY got it working under karmic, but I needed to upgrade to lucid and now it's broken.
When I open Sound preferences and look at the Applications section, Skype shows up as recording when I run its test call... but no sound is recorded? How is it possible that my sound card picks up something recording but doesn't actually record it when I'm in skype?
I read about PulseAudio and thought it might be nice to try (especially the way you could individually control the volume of all applications seems nice), so I installed it and it worked fine.
I rebooted, and now it doesn't work again. Before, when I opened pavucontrol and went to the "Output Devices" tab, it showed the actual output sevices I have. Now it only lists one called "dummy output".
So what's the problem? Also, can I start it before X11 (I guess that putting "pulseaudio --start" in ~/.bash_profile should do it)?
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 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.
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 upgraded to the new packages that came out in early March. Since then I can't run X. If I use a depth greater than 8 my system locks up: blank screen, no response to keyboard or mouse. If I use depth 8 most of the colors on the screen are black, making it effectively unusable. I can exit with ctl-alt-backspace though. I rolled back to the previous versions of the X packages and have no problem. I use 'radeon' video with the ATI drivers. I can't start X with the VGA, VESA, or FBDEV drivers: it reports 'undefined symbol: resVgaShared' I have a Thinkpad A30p with ATI Radeon Mobility M6 LY (AGP) (ChipID = 0x4c59). I build my own kernel. I'm on 2.6.33. I have 512 MB RAM. All other software comes from Slackware packages and are up-to-date.
I am using Open Suse 11.2 on my HP DV6 notebook. I am connecting my television to the notebook with a HDMI cable and the television is unable to find any signal. Am I missing anything here? Shouldn't it be simply connecting the HDMI cable finding the source channel on the television and then I get sound and picture..
I have a motherboard p5bvm-se with 82801H (ICH8 Family) HD Audio Controller. The sound in earphones playing. Sound from the microphone is recorded and reproduced in KRecord => microphone is working. ssv:~ # uname -a Linux sslesarev 126.96.36.199-0.1-default #1 SMP 2010-01-27 08:20:11 +0100 x86_64 x86_64 x86_64 GNU/Linux
I installed skype skype-188.8.131.52-3.1-x86-64 from build.opensuse.org/home:matteotomasoni or skype-184.108.40.206-suse.i586.rpm from [URL]... Microphone does not work in skype!
I ve installed ubuntu 10.10 on hp g62 amd64, but on skype mic doesnt work. I ve tried playing with pulseaudio controller and everything is unmuted as well as in alsamixer. how can I solve it? i think there is some problem with alsa, because when i restart skype mic work by few minutes but after that not.
i just upgraded from Skype 220.127.116.11 to 2.1.047. Now my microphone isn't working anymore and i cannot select it in the skype options. From now on i can only select the PulseAudio server ..
So i have read some howtos for PulseAudio. They say i should starte PulseAudio Volume Control. ok.. Now i should go to the tab "Recording". This tab doesnt exist on my pc. I upgraded to the latest version of this volume control. It still doesnt exist.
I am using OpenSuse 11.0 with KDE4.3
Here are some screenshots:
PS: My mic is still working with applications, that dont use pulseaudio.
I borked my perfectly good 11.2 install, while replacing a failing hard drive. I reinstalled, and now my sound doesn't work - or not quite. I get the left front channel, nothing else. Battle Duel crashes due to sound errors - or I probably wouldn't care.
I am using Suse 11.4, with the Gnome desktop. I have downloaded the VLC player, but cannot work out how to make it play CDs in the CD drive. Right clicking on the Audio Disc icon that appears on the desktop whenever I load a disc doesn't give me an option to Play using VLC. Is there a way to make VLC the default player for CDs?
I cannot get sound to work with my new installed Opensuse 11.2. If I check yast (sound card configuration), I can play a nice testsound. However, Kde (I am using kde 4.4.2) does not issue any sound at all.
