Ubuntu Multimedia :: Pulseaudio Randomly Stops Working?
Nov 10, 2010
Routinely, while I'm working on my laptop, the sound will randomly stop working and I can only get it back by rebooting. I can't seem to find any sort of pattern to what gets it to stop working, but I do have the following programs almost always running: Evolution, Chrome, Transmission, and Pidgin. I usually notice it first when Pidgin stops beeping when I receive IMs.
In the messages log I see lots of messages like this when the audio stops working:
Code:
Nov 9 10:35:04 jbirdjavi-l-u pulseaudio[2031]: sink-input.c: Failed to create sink input: sink is suspended.
Nov 9 10:35:42 jbirdjavi-l-u pulseaudio[2031]: last message repeated 7 times

I'm running Ubuntu 10.10 Maverick Meerkat 64-bit on my desktop with a wired internet connection (with no firewall). For the past 2 days, I have observed that1. Firefox randomly throws up errors like "Problem loading page" whenever I click on a hyperlink. When I click on Reload, the page loads up just fine. This has been happening a lot recently..and I do not remember updating anything consciously. By the way, ipv6 is disabled in Firefox.2. The network stops working all of a sudden (usually indicated by the Firefox error). The Autho Eth0 indication is active, but I am unable to connect to any external machine.
3. Needless to say, this error is manifesting itself in apt-get as well. I get "something wicked happened" errors all the time, and am unable to download or install anything.That this is not a problem with the ISP is obvious because I also have Windows (from which I'm typing this, ironically), which is able to access the internet.Is this a bug in Ubuntu 10.10?

It has to be an update or something that cause this. I've done nothing differently from the other days I use this laptop. I have to keep relogging every now and then because the sound stopped working. I can turn the volume up but pidginrhythmbox, nothing makes noise anymore. it's random...it just started happening today and this is the second time the music went out. anyone have any idea of how to stop this from happening in the future?

I'm using Ubuntu 10.04 since several months and I randomly have problems with the keyboard (PS2). Maybe 2-4 times per week the keyboard stops working all in a sudden. The symptoms related to this can be- the keyboard simply does not react any more to key press- during typing the keyboard gets crazy and fills the lines with the last typed character- opened windows move to the left when touching them at the top bar, keyboard does not react any more. When clicking on a panel menu the focus line is running permanently quickly through all items, and it's practically impossible to click on any of those (so even shutdown is difficult to achieve, and I might need to use a hard reset).
In nearly all cases the problem only disappears after reboot, just very rarely a logout is sufficient to get the keyboard working again. I googled for similar problems and found quite some people having problems with keyboard (and/or mouse) not working correctly under Ubuntu, but I have not stumbled over a similar error description as I have.Just some config parameters on my box: amd64, XOrg uses an Nvidia driver, 3D and Compiz are activated

On a whim vsftpd seems to stop working randomly and any attempted connection times out while waiting for the welcome message.It'll take a couple reboots and a couple "sudo service vsftpd restart" 's and it'll eventually start working again.AFIIK everything is at the most currant version. It just started doing this a few weeks ago.Here is my config file:

I am asking in the wrong place or anything like that, I tried to understand the Tutorials, but I am only human Oh and I am not a native speaker of English, So I also apologize for that...Okay enough apologizing, I will assume that you are all nice people and wouldn't have made fun of my stupidity anywayAs I said I am new to Linux and also to my PC. I bought it a couple of weeks ago and I tried to install Windows on it, but it was displayed in only 16 colors ( I assume this is not connected to my current problem but it might be...) and I couldn't fix that so I installed Ubuntu 10.4.something( It asked me if I wanted to upgrade to the newest version...) . Since then I have been really happy, I only had minor problem with the chat software but after I googled it I found a solution and I even used the console for the first time in my life.
The problem with the chat software is back now, but I don't care about that.My Computer randomly stops working and the screen goes all weird. It switches between a mix of white and black bars, something really colorful and a black screen with text ( I have the feeling it's different text every time) I am not sure what happens after that, because I always turn it off and restart it. It won't react to anything when it is in this weird mode. I don't think there are any special situations in which it happens and I can't reproduce it, it just happens when I don't want it to happen. A friend who uses Linux said it might be a temperature problem, he only knew what I just told you. I am not sure if there is a connection between the time the computer has been on and the time it shuts off...I really like Linux and I would love to use it without ith when I said that I got my PC new ( it was used though) I was trying to say that I don't know whether this is a Ubuntu problem or not

Not sure if I've listed the specs of this machine before, so I'll do it again. 'm running an HP Pavilion 760n with 512MB of RAM and (I think?) a Pentium III processor... not sure on that one right now. It's currently running a laptop version of Ubuntu 10.04.I went to log into my online classes tonight only to find that the computer wasn't responding at all. I did a hot shutdown and restarted it, and now the system isn't detecting the internet connection at all. It should be noted that the connection was working perfectly fine earlier today, perhaps 6 or 7 hours ago.I know it's something to do with my computer and not my router, as I'm on my wireless network from a Windows 7 laptop and it's connecting just fine.
In viewing another thread,..lems+-wireless, I found a bunch of commands that it was said would be helpful diagnosing this issue. That said, below is the output of all the commands that I could think of.
Sudo ifconfig -a
eth0 Link encap:Ethernet HWaddr 00:e0:18:5c:45:7a
inet addr:192.168.2.1 Bcast:192.168.2.255 Mask:255.255.255.0

This happens randomly after a reboot: I can move the mouse cursor and it works perfectly only on the Unity sidebar or whatever it's called. I can fire up applications, but once they're up they completely ignore any clicks or mouse movements (the main menu does not appear on the top bar if I move the cursor in the location that usually makes it appear). They only recognise a click on the close/iconize/maximize buttons.
The mouse works: as I said I can move the cursor and it recognises clicks on the sidebar and the window control buttons; plus, it's connected via a KVM switch both to the Linux box and to a Windows box (from which I'm writing this) and in Windows perfectly.The pattern used to be this: usually while running Firefox, the mouse and keyboard stop responding, and sometimes the whole desktop graphics become corrupted. I can Alt+F1 and go to a text-mode console, but nothing short of a reboot "fixes" things. After the reboot, about two times out of five everything works, three times out of five I get the situation described above.
For the last few hours or so, however, no amount of rebooting and sacrificing goats to the gods protecting sociopaths and Linux software developers have been able to restore mouse functionality. I click on my username on the login windowhere it works perfectly), enter the password and then only the Unity sidebar works: again, the mouse cursor moves, only clicks (right and left) are ignored, as are hotspots. In ubuntu classic there is no place where I can click and launch applications, btw - once I get in I'm basically blocked and can't do anything

I have a problem with my wireless connection in ubuntu (natty with amd64bit) There seems to be intermittent disruption in my connection. Havent seen a pattern as yet, though it happens once a day. After that I cant get it to work at all and only restarting + reconnecting the USB device helps. Dont know what is going on.I have already read these pages : Commands and Wireless Troubleshooting.Here is my line of though1) Given that I am able to connect other devices to it while I am not able to connect through this desktop, I think the router is OK.2) I am able to work with it after restart + re-connection . And so the driver is OK and is loaded. The driver seems to be oK and loaded even while I am not able to connect.So why is this happening and how can I get this under control without having to reboot and re-connect the device everytime.Here are the output for the commands which will give you a more detailed idea of the process. Before reboot while I was not able to connect:

My Acer's Wireless randomly stops working until you fully shut down and start the computer.(Not Restart but Shutdown->Powebutton) I am using Ubuntu 10.04 Lucid.
I am wondering if anyone knows why it would stop working properly, and/or how to fix it?
And since this is a off and on problem I might not be able to provide details immediately from time of crash, since I need my computer on the wireless.
One symptom that really stands out is that the cooling fan is spinning as fast as it possibly can and processor usage is spiking around 80/200 on a process called phy0.(relevancy unknown)
As I was typing this post on my other computer, my laptop crashed and I lost the lshw -C Network output I had. If asked to, I will post the one from when it is working. Also I will post any other info you need from when I can.

Running Debian 8, thunar 1.6.3. Randomly thunar stops redrawing and stops responding to mouse and keyboard input.
This is annoying because I usually have a handful of tabs open and I "lose my place."

I'm having a bizarre problem where my network connection stops working randomly. At first I thought it was a DNS issue since Firefox simply chilled out on "Looking up [hostname]" until it timed out, but after further investigation (pinging IP's, "host" and "dig" being unable to reach servers) it became apparent that I couldn't even access the DNS servers i.e. the Wicked Connection of the East was most sincerely dead.
There are two strange things about this: one, there are no errors except "timeout". The network manager is happy, Firefox is happy until the lookup fails... Two, the failures only start *after* DHCP configuration. DHCP configuration never has any trouble sending or receiving packets. I'm going to try static IP and whatnot to see if that helps, more information later.

For no conceivable reason, pulseaudio will no longer output via the spdif connection on my onboard sound card.Up until now, various applications could output digitally (mostly using via the alsa plugin) fine. DVD playback would passthrough DD/dts bitstreams if the application was set to communicate with alsa directly. The sound profile in Ubuntu's audio applet would have to be set to Analog Stereo Output for this to work, no idea why.
Now, all the works is digital passthrough via alsa (i.e DVDs). So definitely not a hardware issue. Regular audio either via the alsa plugin or using pulse directly does not work so no music/system sounds/flash etc. All sliders are unmuted (see pics linked below) and the volume meters all show movement with sound activity. Changing the Profile setting does nothing, I thought maybe it had been fixed so digital actually meant digital.This has happened before (sometimes triggered by DVD playback and DD passthrough) but usually fiddling with the mute toggles fixed it.Possibly this has been caused by a recent update.

I keep having problems where my audio cuts out in the middle of listening to anything (Flash, VLC, etc). It's becoming very frustrating. I'm running a realtime kernel so I'm wondering if that has something to do with it. Others have reported this problem: [URL]...

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

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.

I've been having problems with it for months, assuming some bug fix would just happen, but it hasn't, so here I am.The general symptom is that I can sit listening to music for around 20-60 minutes, using audacious/banshee/whatever, and the music will make a crackling noise and suddenly stop. Killing pulseaudio and the application remedies the problem, but obviously that's not a solution.I have a ca0106 sound card. [edit: originally had emu10k1 here -- that's a sound card I have that's unused in the same system.]
/var/log/messages usually indicates a message like this, or something similar:
Mar 6 00:22:29 localhost pulseaudio[4872]: alsa-util.c: snd_pcm_avail() returned a value that is exceptionally large: 18446744073709542688 bytes (384307168155 ms).

Following is the specification of my user environment.
Ubuntu 10.04 64-bit
Acer Aspire 5542
AMD Turion 2 X2 M500 (2.2 GHz, 1MB L2 Cache)
ATI Radeon HD 4200
4GB DDR2 Memory
500 GB HDD 5400 RPM
Sometimes, both on Gnome MPlayer and Movie Player, videos clips won't play. I use mainly MKV file format and quite often, AVI. I have also installed Ubuntu-Restricted-Extras.
The players will literally not play. When I scroll, it goes through the video clip as if I'm fast forwarding when paused, and then it would still be frozen.
I only use Gnome MPlayer and it's been working fine until like two weeks ago, and when it happens it's also the same for the Movie Player. The problem stays there until I reboot my laptop.
It's random but quite often and it's now doing my head in. It would be nice if any of you gents could give me a good solution without getting involved another player, because I really like Gnome MPlayer.

My Compaq Presario F739WM laptop has a Connexant HD Audio/NVidia MCP51 (reported by lspci) sound card.Ubuntu has always supported the card with no problem except the random popping noise but then I found a work around for that.Now for some reason, when I first turn on my computer and at login screen I can hear Ubuntu noises, yet seems once I login, no more sound or sometimes the successfully logged in sound.
The only changes that I have since the sound worked, was I installed pulseaudio but that caused no problems with that. The other change was a few kernel upgrades and other packages through normal update manager.I have checked that snd_hda_intel driver was loaded in the kernel and in alsa, all seems well.Pulse detects audio output in it's meter.I also tested the sound card to make sure it wasn't bad, in Windows 7 (dual boot) and it wokrs perfectly.

I am running Ubuntu 9.10 on an HP dc5100MT workstation. Sound works nearly all the time, but once in a while, the sound stops and I have no idea why. The channel is not muted, the volume is 100%, and not even rebooting fixes it. It will just start working on its own.Under the Sound Preferences panel, the output volume is 100%. The channel is not muted. I can get sound out of the internal speaker by changing the connector to "Analog Output (LFE) / No Amplifier", but not out of the "Analog Output / Amplifier" which is the green sound cable plugged into the sound card.I only use this machine as a video player using VLCNothing else.I would like to know some tricks to isolate and troubleshoot this when it happens.

I'm running Ubuntu 10.04 64bit.
This happens on Chrome and Firefox.
When I'm running a flash site like, Pandora, it stops working when I open another tab with flash running like, Hulu. Now it doesn't stop working right away but in time it does.
Then screen on that tab usually goes grey.
Now this doesn't happen all the time but enough to get me flustered.

I am using Ubuntu 10.10. At some point gnome-mplayer (and gecko-player) have stopped working. Try open any audio or video file there is nothing (the progress bar just shows "stopped"). However, Smplayer is working flawlessly for both video and audio files so I am sure it is not a mplayer problem
I have delete the folder .conf/gnome-mplayer but nothing changes.
gnome-mplayer version 0.9.9.2

My problem is this: when I suspend, sound disappears, and I have to reboot to get it back, which is, needless to say, rather annoying. I'm using Ubuntu 11.04, with a low-latency kernel.
I have three sound cards:
1) Delta 1010LT, which uses snd_ice1712
2) Sound Blaster Audigy 2, which uses snd_emu10k1
3) Some on-board Realtek thingy, which I guess uses snd_hda_codec_realtek
I use jack on the Delta1010LT, and I run pulseaudio through jack.
When, after a suspend, I try to restart jack via qjackct, it gives up and prompt the following:
Code:
Acquire audio card Audio1
creating alsa driver ... hw:M1010LT|hw:M1010LT|128|2|44100|0|0|nomon|swmeter|-|32bit

some windows fail to react to my mouse clicks (left and right). This has been starting to happen more and more often. However, one window usually stays working normally, while all others fail. Usually, it's the gnome-panel, but one time, this happened to Firefox. During this, I discovered that clicking a window above firefox, would go through the window, and Firefox would recieve it instead, as if the window wasn't there. Even stranger, firefox was not the active window, and all keyboard and mouse commands were received perfectly, however, the window titlebar wouldn't darken as usual. I can still move the mouse around, but when I keep it still for a minute, I see "View your Appointments and Tasks", pop-up, but it sticks to the screen afterward. A reboot fixes this problem, but only for a while. his also occurs when booting from the live Ubuntu 10.10 i386 Desktop Edition CD. I'm using a Logitech Mouse, but I don't believe this has to do with hardware, since this doesn't happen on Windows.

As the title implies, the sound on my rig stops working after a while. Annoying as hell: I have to reboot my machine to get it to work again, which means that I have to reset my entire programming environment (with five full workspaces). I'm running 9.10 Karmic.

I have a USB mouse which randomly stop in Debian Jessie. It starts again if I disconnect and connect it again.
It can take a couple of hours or just a couple of minutes. The only thing I've been able to find is that it stops more often when I'm scrolling.
I have tried different mice with the same result. I recently migrated from Ubuntu where I did not have this problem so I doubt there is a hardware error.
I can see the syslog updating every time I connect the mouse but I can't see anything when it stops
