OpenSUSE Multimedia :: Pulseaudio: Can't Get Realtime Or High-priority Permissions
Nov 30, 2008
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.
Code:
[Sun 07:25 AM] ~ $ rpm -qi pulseaudio | awk '/Version|Release/ {print $1$2$3}'
Version:0.9.13
Release:3.4
[Sun 07:25 AM] ~ $ groups

I know there already a LOT of posts on the forum about pulse audio. I had some problems upgrading from Karmic to lucid, Pulse just kinda dies, but I left it be. Recently I brought a fresh 1TB hard disk and decided it was time for a clean install of 10.04 to fix that. I am running of a clean install, only additional packages I have pulled down are the Nvidia driver, wine, and VLC.. the rest is 'out of the box' config. Have tried reinstalling 3 or 4 times, I get the same sound problem each time. Pulse works fine to start with, I can play music, play warcraft under wine with sound.
However as time goes on I find that the pulseaudio process takes up more and more cpu time. Eventually it hits about 90% plus then crashes out. The system hangs for a minute, then resumes with no sound. When I run "top" the pulseaudio daemon is no longer running. The only way to get sound back is to manually "Pulseaudio -D" or to reboot the system. This isn't just "a warcraft problem". It happens with Spotify (also under wine) Rthymbox, and VLC. A friend suggested I run the Pulseaudio daemon with a higher cpu importance? Is that sensible? Are there any pages where i can read up on how better to configure pulse? I have read lots of guides about linux sound problems and most seem to be about alsa not pulse.
My hardware info is included below:

It is now almost 3 'o clock in the night here, last 5 hours trying to fix this problem. CentOS always runs perfectly here. I am not a genie with the terminal so wanted to install GNOME on my vps, than vnc but didn't work and did a restart.
Now got this:
Quote:[root@srv1 conf]# apachectl start
Syntax error on line 41 of /etc/httpd/conf/httpd.conf: Invalid command 'Order', perhaps misspelled or defined by a module not included in the server configuration

is there a realtime or low-latency kernel in a repository somewhere for OpenSUSE 11.4? I know I can just compile a rt kernel, but that's a bit tedious and I'd like to avoid it if possible.

Using Ubuntu server 10.04.2 64-bit all up to date.
I am running multi-threaded processes. These use OpenMP in my own code and the multi-threaded ACML maths library. When run in the foreground, everything is fine i.e. if I have set
export OMP_NUM_THREADS=8
then when I start all 8 cores are in use and things whizz along. However, when running overnight and logged out using e.g. 'at now + 1 minute' then the command, I am only getting about 130% CPU and it slows down accordingly. I have tried renice'ing and calling from within a bash script in case sh is doing something odd but nothing seems to solve it. I am sure that in the recent past this wasn't the case.
The libraries being used are shared versions in case that might have any bearing.

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.

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.

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.
How can I get pavucontrol to save my preferences?

Woke up this morning and updated my main myth machine, and now mythfrontend won't start. I get this message:

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'm using OpenSuse 11.4, and I was wondering if anyone else has noticed consistent high CPU utilization with banshee? By high CPU use I mean, when the application is running (whether it's idle, playing music, or scanning) CPU use on my machine is almost consistently at 100% (one core pegged).
Scanning my music library took hours ... like 3-4 hours to scan 9500 songs, and banshee was the only application running on my machine.
Rhythymbox doesn't suffer the same fate, scanning the same library took 5 minutes and CPU busy is less than 2% when it's running or playing music.
I'm running banshee 1.9.3, and I'd rather use it vs Rhythmbox.

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 use divxenc 1.4.6 to create AVI files. Works great. Recently, I started using the option to subsequently convert that to MKV, so I can include multiple subtitles inside the file. Unfortuately, the subtitles show up much to high in the picture. In the AVI format, the subs are just above the bottom of the image. But in the MKV here they appear at about 1/3 up from the bottom. This behaviour shows in both Mplayer for Linux and VLC for Windows. So I guess it's in the file. Is there an updated version of divxenc, or another tool to generate MKV's directly ?

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'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...

Just got Studio 9.10 running and the RT kernel installed. I have a Prescott P4 3.2ghz (hyperthreading) and i encountered what looks like a common freeze problem. I am guessing my cpu will not be supported in the RT kernel since it is pretty old now.I added nosmp acpi=off during boot at the Grub2 menu and it booted fine and I was able to capture some video great.
My questions is, if I remove the smp support by using the nosmp option, do I still benefit from the RT kernel or would I do just as well with the generic kernel I have installed?Eventually I will upgrade do a new system board and processor but for now I just got some life back in this one by switching to Linux

I have investigated loads and loads of options and haven't really yet come across what I need.
I wish to stream the microphone input from a PC using Lucid to another PC also using Lucid on the same network. I don't care about the quality, however, latency is really important. I hope to use it to monitor the cries of my baby daughter, so the lower the latency the better.
I have tired various options:
- FFserver and FFmpeg - latency of over 30 seconds
- VLC - couldn't get it to work with my mic and maxes out the CPU
- ssh server 'cat /dev/dsp > /dev/dsp' - latency of around 5 seconds by audio keeps breaking up with huge delays
- icecast2 and darkice - latency of around 7 seconds but no audio breakups
I've been reading on maybe using PulseAudio to stream the input, but I am not sure if it will work or not...
how to get near real-time streaming audio? As I said, it is the realtime, not the quality that is important...

I've found 2 kernels : Kernel-trace and kernel-rt i tried both of 'em but i cannot boot up suse. The first one gets to 3/4 of the loading bar , i hear the welcome sound and then it won't do anything else. The second won't do anything, black screen.
