Ubuntu :: First Half Second Of Sound Distorted In Maverick (PulseAudio)
Oct 10, 2010
Any sound playing through pulseaudio is distorted for the first half-second or so. Sounds like a buzzing or crackling or something. This happens, for example, in Pidgin and Clementine (music player). If I set these programs to output through alsa instead of pulseaudio, there's no such problem. Also no such problem existed in 10.04. And I tried the fix in the sticky, nothing changed. Probably less than a half second of distortion, really. Maybe 100ms.

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 run two sound cards on my system, one dedicated while the other is built-in on my motherbard.
Code:
cat /proc/asound/cards
0 [NVidia ]: HDA-Intel - HDA NVidia
HDA NVidia at 0xdfff0000 irq 23
[Code].....
I am not able to get any sound recorded through my mic using my XFi card. It records the sound my computer makes, thought. In other words, if I play a song, it'll play through the capture channel making people on voip application hear it. For some reason. But I am not able to get any sound through the mic.
I have tried to mute and unmute every channel in alsamixer, and tried to change the soundcard profile as well in gnome sound preferences. No luck.
If I use my NVidia built-in sound card however, I am able to talk. But after a random period of time, the sound through my headphones begin to distort, badly, while the voice from my mic comes through clear. People can hear me clearly, but I can't hear them at all because of the distortion. It sound really, really bad.
At first I thought it was a bug with skype, but it happens in other voip clients such as gTalk.

I did a clean install to 10.04. Not too many issues except any sound I play sounds like it's underwater and pops while playing. I have tried to do the Pulse Audio install, but every time I loaded pauvcontrol (I think was the title), it would pop up "Connection Failure: Connection Refused." I tried to follow other guides, but they'd all fail because I'd be missing half of the files it changed. I have a Creative Labs X-Fi Fatality card that has given me troubles in the past, but usually, it works. I tried to install Creative's open driver, but again, I had an error when I attempted to Make the directory.

Have been using the exact same hardware setup for a while now (last 5 or 6 releases) and since 11.04, occasionally my sound will go really strange and fuzzy / distorted. It usually happens when I change music tracks I am listening to, but it will then effect all system noises. It will then go away as suddenly as it happened, again if I pause the track a few times to stop the distortion.

So I recently installed Ubuntu 9.10 on my second hard drive. I also just got a new pair of speakers. When I plugged in these speakers, they sounded pretty crappy ie: bad bass, distortion, etc. At first I figured it was because I bought cheap speakers and I was going to send them back. But instead, I booted up windows and voila... The sound was much better.
So I'm trying to figure out whats up (mind you I'm pretty new to Ubuntu) I looked up my sound card: nVidia AC97 and Ubuntu recognizes and apparently has drivers for this. I also followed the sound problems guide posted in this forum. Got as far as the "ALSA driver Compilation" step without much luck. It installed some stuff, but didn't follow what that guide said it would do.

I am running Karmic (9.10) on an MSI U120 Wind. I dislike netbook-remix but that is beside the point.
Last night I made the biggest mistake of my life which is causing a loss of still counting hours. I decided to do an update, due to having enough bandwidth, and security updates to download.
So it finished, and I went to sleep.
This morning I went to plug in my speakers to the audio jack so I can listen to music loud, and it was all distorted. I changed al 8 or 9 volume controls and nothing. I unplugged the wire from the audio jack, and the sound is perfect on my netbook's speakers.
I have tried different wires, speakers, editing config files, removing and purging related packages, and nothing works...
I have been google-ing for hours and everyone seems to have the same problem, but all of the supposed fixes do not work for me...
Here is a pastebin of my Alsa info : [URL]
I fear switching back to winblowz..

I've been working at this issue myself for two days and still haven't come up with anything. On the default system config with Pulseaudio, Skype 2.1 has absolutely no sound, worse, if I call, or somebody calls me, the program becomes unresponsive and I end up having to either reboot or log out and in again. The only option Skype gives me in the sound settings for anything is PulseAudio Server (local) which, (obviously) is incorrect.So after a few hours of trying to sort it out with pulse, I found a workaround involving the REPLACEMENT of Pulse with esound following these commands in a terminal:
Quote:
killall pulseaudio
sudo apt-get remove pulseaudio
sudo apt-get install esound
sudo rm /etc/X11/Xsession.d/70pulseaudio
This works to an EXTENT. I have output sound, Skype makes all it's little beeps and blips and what-have-you, I can hear the other person clear as day,and I'm able to select different sound card settings now. But when I talk to someone or call echo123, my voice comes through choppy, garbled and extremely distorted.Words are run together at a super fast pace, and sometimes even quickly repeat.So then I tried yet another supposed workaround, this involving modifying .asoundrc as seen here:
Quote:
#asym fun start here. we define one pcm device called "dmixed"
pcm.dmixed {
ipc_key 1025
type dmix[code]...
After applying this, I not only changed my settings to asymed, but ALL the new settings it gave me. This time my words are run together AND I sound like some kind of deep voiced monster.Now, once and for all, to save me another two days of searching through google and topics with unanswered pleas for help, can somebody tell me what is going on here and how the hell do I fix it? T_T.I'm running Skype 2.1, (latest build) on Xubuntu 10.10 with a C-Media CMI8738 sound card. Sound works on all other applications and the microphone is solid, since I just switched from Windows and it worked before now.
P.S. just to avoid people thinking I'm stupid and asking this, yes I am positive that none of the sound settings are on mute. XD

I've had sound problems for a very long time with Ubuntu. It once worked fine. Then it got distorted, but I used headfones so that solved that. But now it seems its completely disfunctional. The sound doesn't work at all.

New build to F12. Sound was fine in F11. Now, massive distortion. I have tried every possible permutation of settings. With the main volume control in the top taskbar, there are two positions of level setting where the audio drops to a normal level and sounds OK but any application changing the level or starting to use the Pulseaudio changes the level and its loud and massively distorted again.
In the Pulseaudio manager->sink->alsaoutput.pci-0000-00-11.5.analog-stereo -> properties-> show volume meter, the audio is always maxed out in level. I have tried everything, its unworkable right now. Its possible to start alsamixer from terminal and adjust settings for good audio but any future change reverts to distortion. All changes in Pulseaudio Dev mgr or vol control etc change the audio as they should but do not affect the problem.

It is well known that mencoder can be used to encode video to be burned on DVD with a tool like dvdauthor. The whole procedure is described here:
7.8. Using MEncoder to create VCD/SVCD/DVD-compliant files
Sound for a DVD is normally encoded with AC3. I encountered some cases where the encoded sound was badly distorted. As it seems, the default for the input changed to float at some point. The fix for this is to use:
Code:
acodec=ac3_fixed
instead of "acodec=ac3".

I have a core i7 machine on which I have dual booted Ubuntu 10.10 and Fedora 14. I am facing a weird problem on both the Linux distributions. Currently, I am facing three major problems which are causing me to use my laptop instead of this machine.Most of the times the sound gets distorted ( like the tempo is very slow and some cracks), but some other times it just works fine. ( I experienced this on both Ubuntu and Fedora)Internet at times is very fast and works great, but suddenly it slows down and takes a whole lot time to load. sometimes it just never gets fast.The low resolution flash videos, gets this very weird high pitch sound
Also, I noticed ( I don't think there is a relation between the two or is there?) that whenever the internet is slow, the sound is also distorted and when internet is fast sound works great.The intermittent nature of the problem is making it difficult to debug.

When the opening little music plays during start up, the first half of it is loud, but halfway through, the sound cuts to about half volume. Everything else afterwards is also very quiet. After boosting the volume output to 150%, and boosting VLC's audio output to 200%, the audio is still barely audible on my laptop. I've gone into alsamixer, and it's at max. I once found how to reset the audio card, and the sound was normal again, but only until I shut the laptop off, and next time, it was the same as always.
I'm on Ubuntu 9.10, and using an old Toshiba Satellite laptop. Don't know what my sound card is.

I have distorted sound when viewing SWF files on browsers. Tried both chrome and iceweasel. I have a Dell XPS with debian testing (64 bit), alsa is 1.0.23. Sound is working properly when playing formats other than swf.

I play a flash video, and then play music natively the sound doesn't work. Or I can play flash and have sound but not play music with sound that's on my PC. Or I play my music on my PC, say one song, and the other is high pitched distorted, and rings. I have to exit the program and start it again for it to play nice. How do I resolve this most irritating bug?

I just upgraded from 9.04 to 10.04 and so far I have those problems:
1. Before, everything in my system was in English. Now, half is in English, half in another language (PCManFM, some menus etc). I tried setting up Language Support but it changes nothing.
2. Cursor themes work only when hovering the mouse over "X" buttons in the right top corner of the window. As soon as I move the mouse somewhere else, it goes back to default cursor theme, even though I tried selecting 5 different themes - same result.
4. Hibernation don't work anymore. s2disk saves image to disk and then it resumes it but computer stops on text message along the lines of "Resume completed successfully".
5. Changing volume with keyboard shotcuts no longer works.
6. Smplayer does not display picture anymore when playing movies. The view is just empty. I can only hear the soundtrack. It is using XV filter.
7. PCmanFM that used to worked flawlessly, now after going into 1 or 2 subdirectories stops reacting to clicks on file/folder list. Need to open new instance to be able to do anything and this again would become unusable after visiting 1-2 folders.

I recently bought a monthful of Spotify Premium to enjoy music at the school with my laptop and Nokia E71 with the offline mode - the WiFi at our school is too laggy to stream online music. Under wine, it works quite fine, however, I would totally like to use the native client (yes, I'm too a "yay linux" person like all of you here ), but the music quality is very poor on offline mode. It clips, goes forward, a second back, then back forward etc. The bitrate sounds to be high, an the quality is very good except the annoying clipping.
Anyone else experiencing this? I'm using Ubuntu 10.10 Beta release with Samsung N510 so the cpu power should not be an issue even though the native client uses the resources very greedily. Interesting enough, on my desktop computer (Core2Quad @ 3,3GHz, 4GB 900MHz DDR2 RAM) with the same OS version and software plays offline playlists smoothly (only some occasional clipping)

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 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?

Yesterday I decided to remove pulse (mainly because Skype was unable to work with it) but suddenly the sound icon is gone. After some searching on the net I understood that it was part of pulseaudio, but now I feel a bit lost. Alsa works like a charm instead, but since I also want to use ubuntu to record sound I'm not sure if it will work, and also I have a sound source for my HDMI interface and don't know how switch if I want to.

Just like the title says, when I use mpd with pulseaudio, I get no sound but clients appear to be playing (ncmpcpp and gmpc). Other players such as vlc or mplayer work just fine. If I go under the mixer, I get "no application is currently playing or recording audio" under the "Applications" tab when playing through mpd. In contrast, when I'm using mplayer or vlc, both show up in that tab. It behaves as though pulse is simply not configured to work with mpd.Here is my config (edited out any commented line for brevity):
Code:
$ cat /etc/mpd.conf | sed '/#/d'
music_directory"/media/data/DM/Genre"
playlist_directory"/var/lib/mpd/playlists"
db_file"/var/lib/mpd/mpd.db"

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 ?

I took out some USB speakers that had been working for many months because I needed them on another PC. I plugged the audio out (lime colored female connector on back of Ubuntu PC) into my stereo receiver's VCR audio in (Red and white jacks), no sound. Yes, the cable is fine (same cable I took off the other PC which was working fine), and the receiver is set to VCR. I recall having to go through some hoops to get the USB speakers working way back when. The Pulseaudio volume control shows left and right pulsating bars when I have on Pandora, but sound is obviously not being sent to the right output. I also tried the optical audio out on the PC into the receiver's DSB optical in but again no sound.

I tried to change to 5.1 from stereo and lost sound entirely. To get sound back I had to uninstall pulseaudio, but that gives me sound only on my right front speaker and sub.Whenever I install pulseaudio again I lose sound all over again.

I just removed Pulseaudio from both Fedora and Kubuntu due to the way it stalls other programs from launching after logging into KDE. After rebooting Kubuntu, KDE sounds, JuK and VLC all had sound, presumably via ALSA.
However, Fedora has KDE sounds but no sound in JuK or VLC. When I launch JuK, KDE reports that the HDA Intel analogue device does not work. Could this relate to Gstreamer? If Fedora falls back to ALSA if Pulseaudio is removed, does Gstreamer require additional plugins? Kubuntu has "gstreamer0.10-alsa", but Fedora doesn't seem to have an equivalent.

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.
