Ubuntu Multimedia :: No Line-in/mic Capture By Software, But Sound Plays Directly Through?
Mar 12, 2010
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 have been searching for an answer through most of the recent posts about sound issues but have not been able to find a solution. I am currently unable to capture sound from the "Line" input on my sound card. I do have sound and is working correctly for all applications and I do have P/A disabled (I'm not a huge fan of the sound quality with P/A enabled). I have checked and re-checked many settings but to no avail have not been able to capture sound. I'm sure I may be missing something or have not done something in order for this to work. I was using openSUSE 11.4 on a different pc and had no problems, unfortunately this is a different pc with a different sound card which is on-board so I am not entirely familiar with it yet.
It is a C-media CMI9880 which shows up as a Intel HDA (ICH6) and appears to be configured correctly.

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).

Also I am totally confused by the mixer, it has so many knobs that I am totally lost!
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 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 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 wanted to share this nifty technique I came across for capturing video using the command line. The problem: I have a bunch of old VHS tapes (remember those...?) and need to get them digitized. I have a VCR, and a Dazzle Hollywood DV Bridge which captures video to DV over Firewire (IEEE1394). I first tried using Final Cut Pro, but it wouldn't capture, perhaps because it expects a controllable DV camera, and the Dazzle isn't a DVC device. I then tried my other favorite video editing app, Kdenlive, but it seemed to have the same problem.
I took a quick stab at the other common editors in the repositories (Kino, Openshot, etc.), but no luck with any of them. Then I remembered the dvgrab command, and gave that a shot and it worked, giving me a nice .dv file. However, DV makes pretty big files, which I wanted to compress down to something more manageable. Since I was going to be digitizing hours and hours of tapes, it would be great if I could compress while capturing. A little more googling and I had the answer - you can pipe dvgrab directly into ffmpeg! Here's the command:
the first part starts the capture, in DV1 format, and outputs it to a pipe file. usually you give dvgrab a filename, like
Code:
dvgrab -format dv1 capture.dv
the second part does the encoding:
-f dv: use DV format -i -: input from the pipe -b 2000k: video encoding bitrate of 2000k/sec, high quality -ab 512k: audio encoding bitrate -y: overwrite file if it exists
I didn't set the codec explicitly, for Quicktime it defaults to MPEG4. This worked great, capturing a 2-hour tape into a high-quality quicktime around 2GB. But I also wanted to be able to view the capture while it was going. Since I left the field monitors and audio splitters at the office, I had to figure out how to do this in software. Turns out that the "tee" command does exactly what I needed - the shell never ceases to amaze! Here's the full command:
Code:
dvgrab -format dv1 - | tee >(ffmpeg -f dv -i - -b 2000k -ab 512k output.mov) >(playdv --disable-audio --no-mmap)
tee uses the
Code:
>(command)
syntax to pipe simultaneously to multiple processes. The only thing that didn't work was audio playback, which was choppy and introduced errors in the capture file. I think a little tweaking with the capture rates could fix that.
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 converted an amd 64 bit WINdows machine to Lucid 64 bit. Everything has gone well. I had numerous issues with Pulseaudio that I removed it. Sound with Alsa has been great, including system theme sounds. I can record via a mike as well. What I cannot do is to capture sounds coming through the sound card. When I record I am getting empty files. The mixer indicates that there are two capture devices. Here is some data on my audio card.

I'm trying to capture my desktop sound (Video too, but that part's working) but nothing I try works. I've tried various programmes, none of them work. I tried various things I read on different websites, and nothing worked. I noticed /dev/dsp was missing, and put it back by a guide, but that made no difference and disappeared again now I rebooted anyway
I have installed XVidCap Screen Capture. If I record my screen with XVid Cap Screen Capture there is no sound. But if I record with Desktop Recorder there is sound. What is wrong?
I am unable to capture sound from the sound card. I used to be able to do this with ease in SuSE 10.0 and 11.2. Now I have 11.4 and not only do I NOT have access to the sound card's channels (for base, treble, turning the mic on/off, and line in, Analog Capture Boost, etc) but now I can't seem to get at the settings for capturing sound coming from the sound card. I have tried using the Alsa mixer by way of the terminal and went to the Capture section and turned all of the settings all the way up. I didn't see any settings for Capture Boost as was available with 11.2's Alsa mixer GUI. Here's more of my info:
[Code]...
Isn't there ANY GUI sound mixer available that will give me access to all the channels I require? I not only record sound from my sound card, but I also use my mic at times for Skype and I like to be able to turn it off when not in use, rather than unplugging it all the time. I used to be able to do this with 11.2 and 10.0 and I really liked it that way. BTW, the plug for the mic is in the back of the computer and it's not convenient to have to plug/unplug it from there each time. For some apps, it's just a good thing to have all the sound settings done and in place before starting up the app. This I cannot do right now because of the changes to KMix and the Alsa GUI. I really really don't like this at all.
SOUND from analog Capture is out of sync in Pinnacle Studio 14.

This problem can occur during capture from an analog capture card if CPU utilization exceeds 95 percent. To avoid this problem, configure virtual memory to be "System managed" by following these steps:
1. Choose Start -> Control Panel. 2. Open the System control panel. 3. Click the Advanced tab. 4. Click the Advanced tab. 5. In the Virtual memory box, click Change. 6. Select System managed size, and click Set. 7. Click OK.
I recently bought a set of 2.1 speakers, all is fine. I like to listen to my DAB radio through them. When I boot up, (runlevel 3), sound is there via the mic/line-in jack, but as soon as KDE starts, the sound cuts. I can get it back by:~>alsamixerand then F6 and then scroll to mic, switching to ON and slider up to full and then mic boost up to 65% or so.Can I tell something in KDE to default to mic/line-in on?kmix does not give the full picture I see in other's posts, like here:ImageShack® - Online Photo and Video Hostingjust a single slider under each tab, like this:
When I talk to anybody on Skype, the sound is really slow, it sounds like I am a robot. Its running at maybe 1/2 normal speed. I am using Xine backend and internal microphone.
I'm using a new acer laptop 7736G with x64 ubuntu 10.04.Sound plays through both headphones and speakers when attached. When I use alsamixer and mute either the speaker or headphones, both of them mute.When I alter the volume of the 'headphone' column, nothing happens.If you need any more detail about my sound card etc I can go find it..
i am running Fedora 14 32 bits and have an problem with the soundvolume the sound is too quiet i have checked alsamixergui and the volume is 100 % but the sound is very soft. I have the following soundcard/chip:00:05.0 Audio device: nVidia Corporation MCP61 High Definition Audio (rev a2)have someone any idea how to configure the sound that it plays louder.

VLC started to playing only the audio and not the video, I tried setting the video preferences but all video outputs didn't work. How do I get my video back.
I just installed a fresh install of 9.10 on my amd64. when it starts it locks up right away. i know that this has to do with my nvidia card. i've had to do this in the past. but since it locks up i have no way to get into the command line. ctl-alt-F1 does not work. is there a way to just have it boot right to the command line without loading up gdm?
Is there a way to control the gnome sound preferences widget via the command line? I use optical digital out (IEC95. It works fine. but everytime I reboot there is no sound, I have to go to sound preferences, hardware tab, select my internal audio device, change it from digital stereo duplex to analog surround 5.1, then back to digital stereo duplex, and then the sound works again. I would like to be able to do this via command line so I can write a little startup script and not have to do that every time i reboot.
I decided on a whim to pursue certifications in other operating systems (currently 70-620 and 70-290 certified with Microsoft) and bought a book on Fedora 10 and installed it on my extra PC. First issue I ran into was that due to my graphics card being an ATI I needed to run in text mode (based off posts on these forums) then once I finally got everything under control and installed, it loads directly into Command Prompt (you folks call it GRUB right?) I can log in as root but I can't do anything this way.It won't even allow me to do things like accept the end user license agreement or create new users or see the GUI.
