OpenSUSE Multimedia :: VLC With PulseAudio And 5.1 / 7.1 Multichannel
Mar 16, 2011
I tried Disabling PulseAudio via Yast (didnot remove the packages), and the channels came back in KMix, but then the native apps of KDE, if I can call them so, like Kaffeine started playing 5.1 movie tracks in stereo! In VLC at the same time I had to choose manually 5.1, but then stereo tracks didn't played. Enabled PulseAudio back. Selected Analog Surround 5.1 Output (Phonon->Speaker Setup), backend is GStreamer. Installed the VLC Pulse support package (vlc-aout-pulse). Selected Pulse as the Output Module in VLC. Now Kaffeine plays 5.1 and stereo tracks properly as well as VLC now Automatically switches to 5.1 playback if the track in movie is 5.1 and also plays stereo tracks properly. I guess with PulseAudio we will need all audio/video apps to have some kind of PulseAudio support (built-in/plug-in) or else we will face probs. Now I need them all channels (master, front, centre, rear and LFE). Especially I need LFE (bass) which is too high by default, and I run alsamixer to minimise LFE channel, but as soon as I play a movie or music it is back to 100% automatically.
I have a bunch of 5.1 wavs that I would like to get burned to DVD... anyone know how I can accomplish this? I tried to use DeVeDe, but sort of failed miserably...
I have a Onkyo Tx-sr 308 and a ATI HD4350 Graphic Card. They are connected with HDMI. Is it possible to play Dolby Truehd and DTS-HD as "Multichannel PCM"? With Windows it is no Problem but with Linux my Receiver only get 2 Channel if i play a Truehd or DTS-HD File. Normal DTS and DD works with 6 Channels.
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.
In the 11.4 product highlights it says: "...availability of PulseAudio in a Plasma Desktop session by default", but what does this mean to the average KDE user? The SUSE-Wiki has no entry for pulse nor pulseaudio.
While basic sound works fine out of the box for me, I am confused between Phonon, KMix and PulseAudio. Each does something else:KMix is now entirely useless, right? Phonon only allows me to select which sound device is used for which input. PulseAudio allows me to select indivdual volume per Application through pavucontrol, but it does not replace phonon nor Kmix There is no KDE Plasmoid/Systray thingy for configuring volume with PulseAudio? Is there no single application/plasmoid to handle all sound options in one go?
I think it is pretty bad that pavucontrol is not even installed for KDE-users by default, and it took me a while to figure it out. Or is there another application that a KDE-user should rather use by default?
I mean things work fine, such as using Phonon to automatically choose my Bluetooth headset for voice communication while music and games at the same time automatically use the speakers for output. Changing volume with pavucontrol works, but why do I need separate things for that?
This is not meant as a rant! I am just wondering whether the PulseAudio/KDE-Integration is just work-in-progress, or whether I am missing something important here entirely. After all, 11.4 and KDE 4.6 looks pretty polished to me overall, and so the audio situation sticks out as odd to me.
When I first installed 11.4 I was unable to access the usb webcam mic on Skype. I use Tumbleweed and after a couple of KDE updates I was able to access the webcam mic in Skype. I did this by setting the webcam mic as the first device to use in either pavucontrol or systemsettings>multimedia>phonon>audio capture. There have been many KDE updates since then and now I am back to having no mic in Skype. I will set my webcam mic as described above but pavucontrol will no longer save my changes. It is permanently stuck using internal audio analog stereo as the first capture device. My webcam mic is listed but it is four down on the list and Skype will not access it.
Woke up this morning and updated my main myth machine, and now mythfrontend won't start. I get this message:
Code: 2009-05-12 07:57:50.003 Closing DB connection named 'DBManager0' 2009-05-12 07:57:50.006 Primary screen 0. 2009-05-12 07:57:50.008 Connected to database 'mythconverg' at host: ***.***.*.*** 2009-05-12 07:57:50.010 Using screen 0, 1680x1050 at 0,0 2009-05-12 07:57:50.069 AudioPulseUtil, Error: Failure to suspend: Invalid argument 2009-05-12 07:57:50.070 AudioPulseUtil, Error: Failure to suspend: Invalid argument 2009-05-12 07:57:50.070 ERROR: ***Pulse Audio is running!!!!*** 2009-05-12 07:57:50.070 ERROR: But MythTV was not able to suspend it. EXITING!
So, I googled about, and found this thread on a mythtv dev mailing list: No Start with Pulse Audio (Changeset 20310) | MythTV | Dev Apparently, the new mythtv .21-fixes is incorporating the .22 pulseaudio check. Myth checks for pulse and exits if it can't kill it. I had sound issues with 11.1 before, and tried to remove pulseaudio but created bigger headaches for myself by doing so. Interestingly, if you log into a mythtv session from the xdm, mythfrontend will run. So, pulse isn't loaded at the session level. But, I'd like some other workaround that allows me my normal desktop at the same time!!
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 have the restricted format software installed via one-click-install. I found that in 11.4 mplayer would fail to start playing a MP3 clip, but succeed on the second and subsequent tries, but only within a short time afterwards. A quick examination showed that this was because mplayer was firing off an instance of pulseaudio, which stayed around for a while, then exited. This was not acceptable for a clip played from a cron job so I found the way to bypass pulseaudio for mplayer was by putting this line in ~/.mplayer/config:
Code: ao=alsa Worked fine afterwards. I don't know if this affects the ability to output audio from other apps while the sound device is in use, but I don't have that situation, so this workaround suits me.
I am trying to stream my Desktop through VLC. Video isn' t a problem but audio is.The problem is with the upgrade from 11.3 to 11.4 I got pulseaudio again.I can't find a way to stream all local audio channels with VLC and pulseaudio.I tried "padsp vlc" and used oss:///dev/dsp which kinda works but the audio is very very low as in useless.I also tried setting up rtp/multicast pulseaudio but I couldn't get it working.
I have openSUSE 11.4 KDE 64-bit. Right now I have 20 identical pulseaudio applets that each looks like a circuit board or a PCI adapter on my computer's taskbar. I tried uninstalling then re-installing pulseaudio and the package that choose device (padev?) many times but this problem remains.
I recently upgraded to 11.4, but skype seems to mute all other application streams when a call is active. I can manually unmute them, but it is rather annoying especially when listening to music in the background using Amarok since everytime a new track starts it creates a new stream and is muted again.
I installed pavucontrol just to see if it had more options then kde's built in multimedia settings, but it doesn't (just has the cool how loud is the volume currently). I like the individual application (stream) volumes.
I can be granted permission, and I'm in the proper groups, but pulseaudio tells me I can't get permission.. I wanted to see if anybody else had this problem / knew of a solution / isolate whether it is a pulseaudio, policykit, whatever problem, before I post a bug upstream.
In suse 11.2 when play a video file the media players eats up to 50% cpu and pulseaudio another 18-20% with compiz turn on, when i turn the compiz off media player goes down to 7-8 % and pulseaudio 1-2%. With audio files the picture is different - 2-3 % sometimes 7% pulseaudio and there is not matter if compiz is turned off or on.Is there some kind of configuration should be done ?
I'm using pulse audio sound server in opnsuse 11.3 and latest version of flash player, The problem is playing video or sound with flash player in firefox, Once I play something in firefox sound output it seem like closed to other applications like amarok.
I've been trying to use Wine to make Foobar work in Linux. The program does work, but it doesn't make a sound. For the rest, is works perfectly. I'm having the same problem with any Flash application I try to run: everything works, but without a sound. Amarok, however, doesn't have this problem.Somewhere I found that such problem might be related to Pulseaudio. So I tried going on the Pulseaudio configuration under "other" in the sound panel in YaST, but it tells me that Pulseaudio is not installed or cannot be configurated. I tried installing the package via Terminal, but it tells me that patterns-openSUSE-kde4_pure-11.3-22.1.x86_64 conflicts with pulseaudio given by pulseaudio-0.9.21-10.1.1.x86_64. I would have to delete it, if I wanted to install pulseaudio.Now I don't know where to put my hands. I am not good at this I'm not even sure I would solve my trouble installing pulseaudio, anyway. I'm using a sony vaio VPCEA3C4E with openSUSE 11.3 KDE installed trough USB key.
After update to latest phonon (4.4.0-37) - with kde 4.4.1., it doesn't recognize pulseaudio anymore. I am using xine backend, but I can't find 'PulseAudio Server' device entry in phonon configuration
Is there special pulseaudio configuration so phonon will regonize it? code...
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've had nothing but trouble with Pulseaudio in Fedora 14. I had managed to get rid of it in Fedora 10 with the command: su -c "yum remove alsa-plugins-pulseaudio pulseaudio" I just don't want to have to deal with Pulseaudio anymore. It does not like my sound card and gets in the way. Is there a Linux distribution that does not use Pulseaudio ?
This tutorial is meant for Ubuntu 9.10 Karmic Koala, but it might work in earlier or later versions as well. I wrote this tutorial mostly because it took me a full day of work using lots of help from people on #mpd and #pulseaudio from the FreeNode IRC server.The goal is to get the MPD daemon working using PulseAudio, but without it being dependent on the X server or a session. To do that we must configure PulseAudio to run in system-wide daemon mode (which is not recommended by the developers, but in this case we do not have a choice). This means it will be using the /etc/pulse/system.pa config file instead of the usual /etc/pulse/default.pa. We must also make sure the appropriate user/group permissions are set, or PulseAudio will be rejecting the connections.The result will be an interrupt-less music environment, not dependent on the X server. Meaning we can for example log out and log in without the music having to stop for even a second. Switching TTYs (Ctrl+Alt+Fx) will also keep the music playing (not possible by default). All that and PulseAudio will still be able to detect and configure all your devices automatically.
Instructions: Make sure you add your username to the following system groups: pulse, pulse-access and audio.Do that by going to System --> Administration --> Users and Groups.Click the unlock button (the one with a picture of some keys), then click Manage Groups. In the list of groups that pops up, for each of the previously mentioned groups click "Properties" and select all the users that you want to have this functionality.
I seem to be having a problem with my sound. Every time I start my computer, I hear the sound played at the login screen and the sound played when I login. Right then, every time, the sound cracks up and stops before it finishes. Running "ubuntu-bug audio" shows that ALSA works fine but pulseaudio does not. For reference, "pacmd list" says that there are 0 sinks, 0 sources and 0 caches.
Edit: Solved by a really stupid mistake: loose 3.5mm audio cable. Don't do that. your sound and you're on a desktop computer, go, right now, and check to make sure that you haven't made the same mistake as me.
I am using a couple of Debian Distro (Sid and Lenny) add some Ubuntu into the mix. I made the switch because I was amazed and satisfied with Debian --> once installed, everything works. For me that's okay for o so many years now. I don't question a lot because it just works and I do my job on it satisfactorily. Namely programming the LAMP style programming. Lately I have been using Debian to communicate over the internet -- using Skype and Pidgin and other such things, not to mention listening to music, watching movies, just using the default applications when I originally install Debian.
Along the way, I need to configure something -- that is desktop related -- like the screen resolution of a new LCD monitor replacing the old one and such. Now about my sound -- I'm not touching it because it is working. But that is not the case always. Now I have a constant error -- it is irritating. Rhythmbox don't make a sound always when I have open a web browser (iceweasel, chrome, epiphany) and a site with multimedia object on it -- like a video or something. So how do I correct this? How do I know, too what I am using -- ALSA or Pulseaudio?
Using the Pulse Audio manager does anyone know if it is possible to specify a particular sink or source to be used by a named program? I am assuming it will not be the same as the default.
I'm on 9.10 and I use huludesktop often to watch my Hulu queue. Every once in a while (and more so lately) the video freeze and the sound stutters. I then find that pulseaudio is taking 100% of a CPU (I have a quad core AMD 64bit machine). Killing pulseaudio causes huludesktop to continue without sound and a new pulseaudio starts up. I have to kill huludesktop and resume playback and then everything's OK, until it happens again.
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 need to upgrade Pulseaudio to a version better than 0.9.14 (i.e. at least 0.9.15) in order to get the Pulseaudio plugin in Blueman to work, but despite following these instructions to add the PPA it will not be upgraded!
1) Many of us use JACK for low-latency audio work, but it's annoying to have to turn it on or off to have to allow regular Ubuntu applications to work. It's even more annoying that both can't normally work together -- either JACK or PulseAudio must take control of the sound control. This method allow JACK to do, and PulseAudio just routes to JACK.
2) JACK is kinda super awesome. By routing PulseAudio through it, your regular Ubuntu sound application suddenly get super powers. Pretty easy to do! (Well, we count our blessings in Linux...)
1. DYNAMICALLY You need the PulseAudio utilities and JACK sink:
Code: sudo aptitude install pulseaudio-utils pulseaudio-module-jack And then run this to get PulseAudio connected to JACK: Code:pactl load-module module-jack-sink pactl load-module module-jack-source Now, go to Ubuntu's sound preferences, and you'll see "Jack sink" in the output tab. If you use JACK Control, you can create a script for the above and have it set up in "Execute script after Startup". Then, PulseAudio will automatically load the JACK sink when you start JACK.
2. BY DEFAULT Edit /etc/pulse/default.pa, and add these lines:
Code:load-module module-jack-source load-module module-jack-sink You can test it without rebooting by restarting PulseAudio. In Ubuntu, PulseAudio is started in the user session, not as a system daemon. To restart it:
So, the only way to have bass is to use PulseAudio and edit daemon.conf to enable-lfe-remixing? Well, damn, but alright. how do I fine-tune low frequency reproduction (since my satellites can't handle anything below 150Hz)?
So there's just one DVD (Narnia) that won't play on my Ubuntu machine using Totem: other DVDs play (I've installed libdvdread4 and libdvdcss2 like a good boy) and non-pulseaudio players like VLC play it properly. If I completely remove and kill pulseaudio, it plays in totem fine. It gets to the language selection screen and I select English, but as soon as any sound is involved it doesn't play. Clicking Go --> DVD menu causes Totem to hang. I don't want to be uninstalling pulseaudio, and VLC player is a bit complex for the mother.
The output of totem: Code: marcus@margit-laptop:~$ totem libdvdread: Using libdvdcss version 1.2.10 for DVD access libdvdnav: Using dvdnav version 4.1.3 libdvdread: Using libdvdcss version 1.2.10 for DVD access libdvdnav: DVD Title: libdvdnav: DVD Serial Number: 43D1F9FE (GEAR): libdvdnav: DVD Title (Alternative): libdvdnav: Unable to find map file '/home/marcus/.dvdnav/.map' ..... marcus@margit-laptop:~$
Note that before the last line, Totem does absolutely nothing. It just sits their. Like it's trying to devour my soul or something.
