Ubuntu Multimedia :: Recorded Sound Plays Back Too Fast / Fix It?
Oct 14, 2010
I am having some problems with recording with my laptop. When I try to record something through the laptops mic, usb webcam mic or with desktop recorders audio record feature all playback is too fast (sounds a bit like alvin and the chipmunks :L ) Is anybody else having this problem, or even better know how to fix it ?
Sorry if this has been asked before, I'm running 10.10 and had never tried recording before I upgraded to 10.04. I had the same problem in 10.04 though.

I'm trying to record video off my webcam, and tried two different programs - cheese and wxcam.
I honestly didn't have much luck with cheese - it seemed to work fine, but when it came time to record video, the frame rate dropped to a ridiculous level, making the video completely unusable. I could wave my arm in front of the camera, and it might pick up one frame of that.
Moving on, I tried wxcam, which I like a lot.. however, when I record video with the xvid compression, they play back considerably faster than they were recorded.

I'm running Ubuntu 10.10 in a Samsung R510. I've tried to record sound with an external microphone and there have always been a permanent noise accompanying it.I thought it could be the internal microphone, that's causing the noise, but even when I disabled it the noise remains. Or maybe I didn't disable it the right way !

I have recently installed OpenSUSE 11.3. I can play audio files, but there is a problem recording, namely the recording is way too slow. This was tried 3 ways: in Audacity, in Skype (making a test call), and using the arecord command in a console, as root. To make the playback sound normal, I tried taking the already-recorded file and speeding it up in Audacity. It was necessary to speed up the recording by 50%. I've tried updating alsa and other suggestions which I could figure out, and run the scripts for diagnostic information. BTW, I'm using a headset plugged in to standard 1/8 inch mic and speaker jacks, not a USB headset.

when i play a song in banshee, or a videos video, i get no sound at all. however, in banshee 1 3 minute song will appear to play in about 20 seconds (the progress bar speeds along), and videos videos play back in ultra-fast motion with no sound. weirdly, when i go to system settings -> multimedia, and click test on the default sound device, the kde login sound plays back fine. this worked when i first installed; does anyone know what's going on here? i think it may be a problem with gstreamer?

My wife is taking an online language course that requires Windows in order to record and playback speech (for pronunciation training). I decided the easiest thing to do would be to clone a VM I use on my machine for tasks that can only be accomplished in a Windows environment. I did so, and successfully installed the speech recognition utility on the Windows guest VM. Unfortunately, although the microphone works just fine--I can hear my voice in the headphones--no sound is recorded by the speech recognition utility. Just to be clear, the microphone is fully functional under GNU/Linux. My wife has been using Skype without any issues at all. That is, Skype used to work. Somewhere during the course of trying to resolve the voice recording problem I managed to break Skype. I have no idea how.
It's a long story, but I'll try to be as brief as possible. When I could not get the VM solution to work properly, I thought maybe the problem was with the VM, so I checked the original copy on my own machine. No problem there. Windows sees and hears the microphone just fine (using the testing utility under sound configuration). So how is it possible that the microphone doesn't work in the cloned VM image? Before you stop me, allow me to note that both machines have identical motherboards, and both are configured to use the onboard sound. Sound works on the Linux host and the Windows guest VM. Both sound and microphone work in the original VM image on my machine, but only sound works in the cloned VM on my wife's machine.
If you've followed me down the rabbit hole this far, please continue with me a bit further as things get stranger and stranger. After triple checking all the setting in KMix (I'm running Squeeze/KDE on both machines) to be sure they were identical, I noted that I was unable to view/add/enable the "channel" option on my wife's machine. Why, I have no idea. As I said, the machines are identical as can be both regarding hardware and software. Out of desperation, I decided to set up an account for my wife on my machine. I created her account, made sure she had the necessary audio permissions, then cloned my VM to her account. Same problem.
I would love for someone to point out what I'm missing here. Same hardware, identical VM (clone), same permissions, same sound configurations in KMix and under the Windows guest VM. How is it possible for the microphone to work for me, but not for my wife? Is there some mystery configuration file somewhere that has magically been altered for her account alone? The worst part about this entire process is that I've broken my wife's Skype, which is a big deal seeing as we live in a tiny country in the heart of Africa and cell phone communications are very expensive.

openSUSE 11.2 64bit
libxine1 from Packman
00:14.2 Audio device: ATI Technologies Inc SBx00 Azalia (Intel HDA)
Maybe it's just an Amarok2 problem, but whenever another app (for example Konversation) plays a sound file, the audio instantly cuts out (in Amarok2) and will not come back unless I quit Amarok2 and restart it.
Amarok2 has only the options - "HDA ATI SB VT 1708S Analog" or "PulseAudio" (which is NOT installed).
alsa-info here - [URL]
Also I am totally confused by the mixer, it has so many knobs that I am totally lost!
here's a lovely pic - [URL]

I have loaded 9.10 ( 64 bit ) under VMWare Workstation 6.5 and each new install results in fast audio ( mp3 ) and video ( avi, mpg, etc ) playback. I am trying to keep the installs as vanilla as possible. My other VM distros are fine.
I am creating the VMs under vista x64, SP1 ( now updated to SP2 ), using workstation 6.5 ( will upgrade to 7 later on ).

I've tried walking myself through all the sound help threads, but I am not having any luck. Sound was fine a few days ago. But now I get nothing. I uninstalled and then reinstalled both alsa and pulseaudio... and their respective mixers bounce around like they recognize sound is being made, but nothing comes out of the speakers. sound does work in windows so the speakers aren't blown. nothing is muted to my knowledge... alsa and pulse mixers are not on mute. output is set to Internal Audio and not HDMI stereo, though I never know which profile to be using.. i've pretty much tried them all to no avail. results of aplay -l

I'm on Kubuntu 9.10, using Totem to play .wmv files, and certain of them cause the player to search for an audio codec (wmap?) that is never found. The video played without audio after that. So I followed advice to remove ~/.gstreamer-0.10, and reboot. A new .gstreamer-0.10 directory appeared, but now, Totem will not even play the video. It recognizes the audio codec however. The video codec shows up as "Windows Media..." but resolution is 0 x 0, and nothing ever appears in the window. I tried uninstalling and re-installing w32codecs and non-free-codecs, and removing the registry files under ~/gstreamer-0.10 and using gst-inspect to rebuild the database,
but nothing helps.

After a fresh install of opensuse 11.2 I followed the multimedia guide to install mm-support. Sound is working, results in xine are excellent. Compared to 11.1, vlc now plays sound with drops about every second. To be more precise: sound is ok for several seconds, then a first drop appears. Thereafter the time between the following drops slowly shortens. After a minute or so, the drops come in intervals of about a second.

I installed Ubuntu to a flash drive and it worked all dandy like. However, on other computers the audio doesn't work, neither can I install a driver for the graphics card to use effects and (at least so it seems to me) run 3D games. Is it trying to use the same hardware that it did on the first computer I used and therefore hasn't installed the right stuff?
EDIT: I can 'play' music, so I think the codecs are fine, but no audio comes out, so I'm thinking it must be a driver problem.
EDIT2: Apologies, I checked the "Comprehensive sound problems solution guide" and was able to fix the audio simply by unmuting the speakers. However, the graphics problem remains.
One other tid bit that might be relevant is that the first time I booted up on a different computer it did tell me (in different wording) that the graphics might have trouble because it was set up for a different hardware system, so I told it to set up a new configuration and that seemed all dandy.

I got a 5.1 desktop sound sys for my recently built gaming rig. It sounds great. On Windows, that is. In ubuntu when I'm playing music, primarily when the subwoofer plays the bass, the speakers sound like they're farting and ripping phone books in half. Also, they get very statticy and sort of quiet. In sound preferences, analog stereo duplex is selected, if that's of any value. How can I get good sound playback in ubuntu?

I have a problem with trying to capture sound through the input jacks on my computer. The sound plays through from the inputs to the output, and it's volume is controlled by alsa mixer, but no programs can pick up the stream, including the PulseAudio and Gnome Volume controls.I have tried many of the suggestions to be found in these forums for sound issues, including removing Pulse, configuring the model in alsa-base.conf, and messing with every setting I can find.Here are the outputs from the commands from the troubleshooting guides:

I recently installed ubuntu and installed amarok and tuxguitar, both of them have no sound. Amarock just skips all the mp3s i want to play, and tuxguitar just plays without any sound, no error message or anything. I ran these both ot of the applications menu, not terminal (I dont know how to run them out of terminal).

I just installed wheezy and upgraded to jessie. I had previously gotten sound working in wheezy by installing the flashplugin-nonfree and flashplugin-nonfree-extrasound packages, after configuring my headset in system settings. However, now I can't get sound to play in firefox. I've installed flashplugin-nonfree, flashplugin-nonfree-extrasound, and pulseaudio, still without luck. The volume is turned all the way up in alsamixer, sound tests play fine, and I can play music in VLC without any problems. This leads me to believe it's not a problem with drivers, but with some package I'm missing that will allow firefox to play sound. Sound wasn't working in the default video player either, before I installed the flash plugin. Is there something I'm missing?
Also, sound doesn't play on Konqueror either (KDE browser), which seems to indicate it's a problem with flash and not with firefox itself. After removing the flash plugin and installing pepperflashplugin-nonfree to ensure the pepper plugin was used instead of flash, sound still would not play in chromium, so I reinstalled the flash plugin and still don't have sound in any browser.

I recently tried out recordMyDesktop (not the GTK+ frontend, just the CLI program, I wanted to Keep It Simple this time ), and found that the videos it records/encodes show massive motion-smearing artifacts when played back. This is without the "--on-the-fly-encoding" option; with it, the video looks fine (i.e. has no artifacts other than the typical ones found in any compressed video), but it plays back too quickly (the time-step between frames is too high, thus making everything go too fast when the video is played back, even though the frame rate is low). Here's a screenshot of the video playing, showing what the artifacts look like (they're nasty!).
I've searched Google and LQ about this problem to no avail: either there were no relevant results, or it was just a post on a different forum asking basically the same question, but with no answer. So apparently this problem is either really rare, or it's something specific to my configuration, and mine alone (highly unlikely).
System specs:
CPU: Intel� Core� i5 430M @ 2.27 GHz
GPU: NVIDIA GeForce� 310M w/ 512 MiB VRAM
RAM: 4 GiB
Command used to record:
Code:
recordmydesktop --fps 30 --no-sound --no-frame --overwrite -o /home/mrcode/Videos/capture.ogv
I've tried different options, such as --quick-subsampling, as well as tweaking the video quality and bitrate settings (--v_quality and --v_bitrate), all of which did nothing to change/get rid of the artifacts.

I am new to this forum and have recently switched to Ubuntu. The OS installed without a hitch and was able to get video card, wireless internet installed with relative ease. However, I have encountered a problem installing my E-mu 0404 PCI sound card via the ALSA packages in Synaptic.
Code: 04:03.0 Multimedia audio controller [0401]: Creative Labs SB0400 Audigy2 Value [1102:0008] As you can see once the packages were installed the OS could see the hardware ok, but when I tried playing a standard MP3 file (16 bit, 44.1khz, 192kbps) in Totem it started playing the file back around 15-20% faster than normal? To me it sounds as if the software is playing the audio back at higher sample rate than 44.1khz hence the faster speed, though I'm not 100% on that.
The next thing I tried was playing the same file back in VLC and it was exactly the same (15-20% too fast), but this time it was horrible and glitchy as well, almost as if the audio buffer size was set to small. The same thing happened when I tried playing back some flac and wav files (all 16 bit, 44.1khz) also. I have searched google (and read the comprehensive sound card guide on this forum) and read several forums, guides, etc. for anybody posting the same issue with this particular card but could find nothing. From all reports I've read this card should work fine under ALSA. For the record I'm using Ubuntu 10.10 64bit kernel running on a Dell Dimension 9200 (Intel Core2Duo E6400 2.13ghz) with 2GB RAM.

I am trying to record using a microphone on a machine running Fedora 14. The microphone itself seems to work fine when plugged into a Windows laptop, and the Linux machine is able to play sound just fine. However, although I can record using the microphone (using arecord or audacity, for example), the recorded audio is super, super quiet. I have run alsamixer, and experimented with every capture source. Anything which had any effect (using arecord -vv to see the dynamic sound level) has been turned up to 100%. Still, recorded audio is barely audible.
I have run:
yum reinstall alsa-utils alsa-plugins-pulseaudio alsa-tools-firmware alsa-firmware alsa-lib
But that made no difference. I ran alsa-info, and the output is here: [URL]. Why my recorded sound is barely audible? My next step is probably going to be to boot to Ubuntu, just to see if it has the same problem.

I have accidentally deleted the soundmenu in the panel that comes with the new ubuntu 10.10. After going through various posts all I can see, is that the solutions provided only provide the applet for sound control and does not have any integration with any of the music players (in my case Rhythmbox).I really want that menu back as it made listening to music while using multiple desktops very easy.

i have a problem with sound. Previously my on-board sound controller was identified automatically and worked flawlessly. But now I don't have any sound in the system with the only exception of Xine-based applications (Xine itself, Kaffeine-xine and Amarok still play fine but all other software is silent)Have anyone had this problem before.I'm using Debian Lenny stable with KDE 3.5.

The only thing really missing from this install is this issue with the sound. I've searched all over the forums and i found one thing where you get the model and codecs and write them to a file, however, I can't seem to find what my "model" is because none of the postings have anything about Lenovo laptops. Here is the command they all asked for:
Code:
With that info, how do I get the model, and how do I get my speakers to stop playing when headphones are plugged in. Also, I don't have any software installed like pulse audio either, so it's not that.
