Pavucontrol/Pulseaudio hangs sound playback

Hello everyone
I've posted on this before, and the bug went away, but now it's back and I just wish it'd go away permanently. For reasons I can't explain, trying to control the volume with pavucontrol (or, it seems, any volume control that interacts with pulseaudio) suspends sound playback. And then pavucontrol crashes with a callback timeout failure error.
I've followed all the various guides on setting up Pulseaudio. I've experimented with setting sinks, with setting sound outputs, everything. But time and again the pavucontrol applet brings the sound to a halt. As far as I know I've installed everything that might be needed. I used to like Pulseaudio, the whole control-volume-of-individual-streams is great. But it just doesn't work. And yet it's one of those features, which once you get used to it, is really hard to live without.
How can I fix this once and for all?
EDIT: Reading /var/log/errors.log I've noticed that Pulseaudio is failing to set hardware parameters with a connection timeout.

Have you tried setting the pulse volume from alsa (amixer)? You should really bring this to the pulse mailing list, since this sort of bug is probably hardware/driver level and not very simple to debug.

[Pulseaudio] Pop sound when the first stream starts, auto-suspend?

Hi,
I've been having a popping sound issues whenever a Pulseaudio sink was opened. At first I thought it had a link with the power saving settings of snd_hda_intel, so I changed those two settings:
power_save setting = 0
power_save_controller = N
Sadly, it doesn't change anything.
I also tried to disable auto-mute in alsamixer. It didn't work.
Then, I tried to investigate on pulseaudio's side, and figured the sinks are disabled when they are idle, so I commented out this statement in /etc/pulse/default.pa:
### Automatically suspend sinks/sources that become idle for too long
#load-module module-suspend-on-idle
However, if I do that, the device will still be suspended when the last stream ends, but won't come back to life except if I select the device again in pavucontrol while a sound stream is running (super weird).
Any leads? I'm a bit desperate...
EDIT: I'm experiencing what's been described here: Red Hat - Bug #520403 - but the solution they proposed does not work for me. I also followed the guide for ALSA Setup on the wiki, and read the section talking about Popping Noises, but nothing works for me, I un-muted the Line-In too. FYI, my audio codec is a Realtek ALC892.
EDIT 2: Noticed it does the same thing when I mute the volume.
Thanks!
Gabriel

First link is to linux 3.14 version. At least I assume it gets passed on directly, if that really is the case, I do not know. Just try it, hardware damage risk is minimal.
Looking at the mask, I think it takes up to 31 samples. So try with 1, 2, 4, 8, 16, 24. I may be very well wrong about this.
Since I already have 0 and 1 in the 'trial matrix' I'll add 24 only. Adding the combinations with 2, 4, 8, 16, 24 is too much for me

On most keyboard layouts (also on the Polish programmer one) hyphen is one key one keystroke, where underscore is two key one keystroke, therefore more error prone and less efficient.
Wow, I didn't know that! What do you know! Linux being bitchy even about capital letters made me think it would be even more bitchy about '_' vs '-'.

Sound playback: no sound, abnormally high bitrate.

I've been reading up on using JMF for simple sound playback all day, and I've seen countless examples that do the same thing I'm doing, but in every instance, I get absolute silence. Additionally, it seems that the read bitrate is higher than it should be, according to the control panel's properties dialog (e.g., 480Kbps for a 192Kbps mp3).
The code always goes something simple like this:
    Player player = null;
    try {
      MediaLocator ml = new MediaLocator(new File("BGM.mp3").toURL());
      player = Manager.createPlayer(ml);
    catch (Exception e) { System.err.println("BGM messed up"); }
    if (player != null) {
      player.addControllerListener(p);
      player.start(); //this does realize and prefetch
    }I put some debug output statements in my controllerUpdate function, and it is indeed realizing, prefetching, and starting playback of the file. I have tried this with both wav's and mp3s (I have the mp3 plugin installed in addition to the JMF 2.1.1e itself), and have always gotten the same result - MediaTime progresses too fast, roughly 2.5 times faster than it should (5 seconds for every 2 real seconds), and I get no sound.
At this point, after having tried at least 2 examples found online in addition to my own code, I'm convinced there's something up with my Java runtime in itself, not just my code... anyone have any experience with this kind of problem?
System Info:
OS: Windows XP Pro SP1
Java Version: 1.5.0_02
JMF Version: 2.1.1e (zip version [no performance pack], with mp3plugin added)
Thanks in advance for any help.

Do you use it in an Applet ?
I'm also unable to play any sound with Java(TM) Plug-in 1.5.xx the
plugin to all browsers nowadays.
You mentioned you used it on Windows 98 SE.
The old IE browser used the build in javaVM. It worked - just look at
the java consol and you see a lot of warnings and errors -, but in the
end it played video and sound.
The only solution I found is to use Java(TM) Plug-in 1.4.xx. The
'automatic search for update' box must not be checked, otherwise it
will update to the newest Plugin and you face the same problem. If you
want to place an applet on your homepage, just use video only - until
now it works correctly on ALL PLATFORMS.
There was a Bug Report 6245070 where I was asked as well to give an
example a year ago, but this was all - no response at all. In this
applets I used
Content Type : video.quicktime
Video Encoding : h263
Audio Encoding : ULAW
not even mpg3!!
I tried to compile the whole JMF Version: 2.1.1e with J2SE 5.0 and
Standard Edition 6 Beta. At one version I changed all the
inconviences like the reserved words "enum" ..., and an other version
with old style, which is possible with Standard Edition 6 Beta.
It seem's the problem is not in the part you are able to compile. It
seems to me it is in the sound.jar api, but I really don't know - just
trail and error.
Conclusion only JRE lower and until version 1.4.xx will work.
It would be a pleasure to me if I'm wrong and there is a solution.

Lost sound playback for movies, podcasts, etc. How can I regain playback?

I have lost audio playback for movies, podcasts, etc on my iPad2. New user. How can I get my sound playback back? It worked initially!

discovered the solution from another discussion group.
Double clicking on the "home" button of the iPad opens a list of apps across the bottom of the screen. Moving to the left end of this display there is an audio slide bar which was set to the lowest part on my iPad. Moving this setting to a mid level restored sound to the video feeds I was having trouble with.

Sound/Playback Stops Suddenly in Windows Vi

I have recently encountered a very strange problem with my computer: the sound/playback stops working randomly. For instance, let's say I've just rebooted my computer and have launched WMP to play some mp3s. It will work fine for anywhere from a day or two to, at minimum, a few minutes...and then, once an mp3 file finishes playing, sometimes I will hear a weird sort of "squeak" coming from the speakers--after which playback will not work--but even if I do not hear any sort of strange audio, if I click another file to play...WMP will load the media, but will not play it. The play button will switch to pause as normal, but the file will not play. The exact same thing happens in *other* media players, as well: iTunes, J. Ri'ver Media Center...even WinAMP. I have a SoundBlast X-Fi Platinum audio card, and have been running it under Windows Vista Home Premium since January with no problems. I have all the current Vista drivers installed for it, and *have* had them installed for months. I'm really not sure whether this problem is software- or hardware-related, hence the reason I'm crossposting this to?Microsoft's Vista?forums as well. What should my next step be? I'm not really sure where to go from here. Thank you!?Dere C. F. Pegritz

I have the same problem here too. Vista Ultimate 64bit4Gb RamX-fi Extreme Gamer Pro?Currently have to re-boot when it happens. I have just installed the new drivers (30 May) - I will see if this has any effect!?RegardsBrian.

Sound playback in LT?

a way to hear sound playback on an imported fcp movie file in LT? I could only get video playback, but sure would B helpful to have sound instead of just markers- is it a setting?
thx

Nope. Just markers. Bottom line: There's no audio playback support in LiveType.
It's a silent app. That's a feature! No pesky sound annoying your studiomates.
Your best bet is to have LiveType and FCP open at the same time. Save your LT project, and import it into FCP. When you change something in LT and want to preview it with sound, go to FCP (use Expose and you'll look cool), and play. It will automatically recognize the changes you made in LT. If you need to tweak, go back to LT, change things, and come back to FCP to play. it's really not all THAT clunky.

BASICS - PulseAudio - No Sound

Hello!
I have a fresh Arch installation and everything works fine, but I lost my sound.
That's right, it worked at first but now it doesn't. Didn't change anything regarding sound packages, only had a reboot inbetween.
pavucontrol shows me all my devices (I have an USB DAC in use) and the mixer is unmuted.
The volume meters/bars are also acting when sound is played back, but it just won't reach my headphones, it's total silence.
I don't know where to look anymore but will provide any information needed to solve this.
Really want to keep using Arch again.
Cheers!

I'm back. My sound doesn't work anymore.
It's not Arch specific though as a fresh installation of Lubuntu has the exact same problem.
I can play an audio file with
aplay -D plughw:1,0 /usr/share/sounds/alsa/Front_Center.wav
and I hear distorted crap.
Replugging the USB port doesn't help anymore, switching USB port doesn't help either.
It is something related to alsa (I GUESS!) because Lubuntu has the same problem withouth an installed pulseaudio package.
Can anybody help me out fix this?

Pulseaudio no sound

Followed the wiki and started daemon, used the fuser commands to check that nothing was using sound first and restarted daemon after closing all apps but no sound.
Here is my /etc/asound.conf:
# Use Pulseaudio by default
pcm.pulse {
type pulse
ctl.pulse {

pcm.headset {

ctl.equal {
type equal;
#pcm.plugequal {
# type equal;
# Modify the line below if you don't
# want to use sound card 0.
#slave.pcm "plughw:0,0";
#by default we want to play from more sources at time:
# slave.pcm "plug:dmix6";
#pcm.equal {
# Or if you want the equalizer to be your
# default soundcard uncomment the following
# line and comment the above line.
#pcm.!default {
# type plug;
# slave.pcm plugequal;
#------------------------end of working file
So my setup works like this: I use plug:dmix6 for anything that is 5.1, while default upmixes stereo to all speakers for anything else (music, 2channel video, youtube, etc.). It all works great and has for a long time, but now I started using XBMC and I need to be able to switch between using dmix6 for movies/shows, and default for Music.
I have tried various video/audio files with mplayer using -ao alsa:device=pulse but get no sound.

With Pulseaudio, no sound with other apps when jack is running

I need to be able to run other sound apps with Jack running (and, ideally, be able to route sound from those apps into Ardour via Jack). So I installed PulseAudio, along with pulseaudio-alsa, and blacklisted the snd_pcm_oss module as per the Arch wiki. At that point I logged out and back in and I still had sound in all my apps. I then set up pulseaudio over jack as per the Arch wiki instructions here:
https://wiki.archlinux.org/index.php/Pu … rough_JACK
including the scripts for qjackctl. I now have sound only in my apps that use Jack; Ardour, for instance. Can anyone help? I'm using KDE 4.6 with the Phonon-VLC backend for sound.

Do some debugging first, please. The wiki instructions are really quite hackish (but there's no real good way to automate this as of now).
Kill pulseaudio, start jack (till here you're working fine I see), restart pulseaudio, try and load the jack modules and check qjackctl or pavucontrol to see if they're connected. If not, find the error logs and google them. Then come back here and ask more.

Pulseaudio delayed sound issues with simultaneous output

I've got Pulseaudio set up to send simulataneous output to analog speakers and HDMI monitor-internal speakers. However, frequently when no audio has been playing for a while, when I do something involving audio, the simulataneous output is out of sync (one of the two output is receiving delayed signal) and so it sounds odd, echo-y, and awful. I usually have to kill pulseaudio and restart to get it back working.
It's not always been like this; the issue seemed to have started a couple of months ago.
Any suggestions on a fix?

SB Audigy SE (SB0570) / Win 8.1 64bit completely freezes on sound playback

hi there,
I got a problem: my audigy se doesnt work on windows 8.1 64bit.
I freshened up my pc and installed a clean win 8.1 os on a new harddrive.
I tried installing the official SB24_PCDRV_LB_1_04_0090a.exe driver.
I got a audigy se (sb0570), and driver installation works fine. the card got recognized and it can play a sound, but after a few seconds my whole PC freezes without bluescreen. it doesnt matter if it is a flash video, a mp3 or just a windows sound; it always freezes. when the sound device is disabled, the system runs without freezes. I can start a playback, ofc there is no sound, but the system is stable.
my card works fine on win 7 64bit with older drivers. plus, I am using the support pack 2.6 by daniel_k (I still use my old SDD with win7 on it and everything works fine). I also tried support pack 2.6 on my win 8.1 system but it doesnt even recognize the card. the newer support pack 3.0 does recognize sb0570 and actually the sound works for about 10seconds (my 5.1 system works fine for that 10 sec, all speakers are getting a signal, but then it freezes...).
so, both the official and the unofficial drivers are not working.
has any1 a clue?

There is also a hotfix in the main post, so those who have already installed Support Pack 3.0 don't need to reinstall.

[SOLVED] No sound playback in Cinelerra

I am using Cinelerra-cv ( the "pacman -S cinelerra-cv" version) and when I try to play a video in the timeline the audio does not play and I get the following error:
AudioOSS::open_output: No such file or directory
The sound works in other applications just fine and I had this same exact problem in Ubuntu 11.04. So do I need to install or configure something? or is this just a bug in Cinelerra?

On my system I am using KDE4 which I believe requires PulseAudio and I have found out that OSS and PulseAudio conflict with each other.
However I did some research and I found a solution on the PulseAudio article of the ArchWiki to make OSS programs work with PulseAudio.
As mentioned in the Wiki I installed ossp:
pacman -S ossp
after install, I ran the ossp daemon:
rc.d start osspd
then I ran Cinelerra using the padsp command:
padsp cinelerra
and the sound plays in Cinelerra!
So as it turns out I just needed to install or configure somthing.

CS5 No sound playback with HD422 clips

Hi, I installed CS5 Master parallel to my CS4 Master installation on a Windows 7 (64-bit) system. I opened a new HD422 project and imported HD422 1080i50 footage. If I play back the clips on the timeline or through the monitor I can't hear any sound. There is just a faint noise. If I import an EX3 clip the sound works fine. Does anybody has this problem, too?
I also have the Matrox Axio LE card installed with my CS4. According to reports from users they were able to install CS5 parallel and it didn't break their AXIO funtionality. In my case the importer process is crashing, when I'm opening Premiere CS4. I thought this should work fine. I don't know if this issue has any influence on my HD422 playback.

Marcus,
There have been several reports of Audio issues with Matrox cards. Going back to the CS4.2 days, Matrox issued an updated driver that got the Audio issues sorted out for many, if not all. That would be the first place that I would look.
Good luck,
Hunt

G4 Hangs, Sounds like an Airplane Taking Off

My G4 has been running smoothly on Leopard so far. Lately, though, it has started hanging often... no spinning wheel, no opportunity to force quit... it literally freezes. I hold down the power button to turn it off and then on reboot the fan goes crazy... sounds like an airplane taking off.
I have fixed disk permissions. Reset PMU. Run fsck -fy. And it's still doing it.
I am also running several usb devices through a belkin hub: iPod shuffle, external maxtor 80Gig for time machine, and occasionally a canon powershot camera.
Last time I tried to import photos off the camera it had all kinds of trouble. Had to reboot several times.
I realize this thing is getting old... but my whole life is on it and I can't really replace right now. Any ideas?
Thanks!
Josh

If this is a Mirrored Drive Doors model, the fans are likely working as designed.
There are circuits inside that run the internal fans on their highest setting by default. When the computer is running properly, the software periodically checks the CPU temperature, and sets the fan to an appropriate setting -- almost always less than maximum.
At initial power up, and when the fan hardware is ignored (not turned down) for some large part of a minute, the fan circuits revert to the default, maximum setting to keep the CPU from getting so hot it is damaged. Sure is loud, isn't it!
If you are running 10.4 or later, boot it up (if you can) and check About this Mac > More Info > Diagnostics -- to see if is detecting any failures at startup.

Menus switching, hanging sounds etc.

I think my poor mac has been infected with a malware of some kind.
When I click the apple icon in the top left, the menus start moving to the right untill it reaches the end, then starts over. It is impossible to click the choice I want. When I click the desktop, it selects the first icon, if i click several times, it just select the same icon again.
Sometimes it makes a sound like a cd hanging, over and over again.
Any suggestions?
Thanks for all the help I may get:-)

Haha, I found the reason.
I have a Apple Bluetoth Keyboard, this is connected to my iPad. When i turn the bluetoth off at the iPad, the keyboard is searching for other devices to connect to. It was earlyer connected to my mac, an therfor it always connect. When the keyboard lies in a bag and maybe some of the keys are pressed it makes the mac look like it's having a virus of some kind.
The solution is to remove the keyboard completely from the bluetoth devices.
