Fedora :: Analog Audio Capture Not Working?
Mar 9, 2010
I'm trying to get skype going in Fedora 12 KDE x86_64 (fully updated). I did some testing with and without the pulseaudio server installed. With the pulseaudio, I didn't manage at all. I know I got it working before _without_ pulseaudio, but after a yum update the pulseaudio got reinstalled and the mic stopped working. Now I traced this problem down to what I think is wrong: I have a HDA Intel sound card, but 'cat /proc/asound/devices', doesn't show me any analog capture input at all:
cat /proc/asound/devices
2: : timer
3: : sequencer

I installed a fresh copy of Fedora 14 a few days ago. The default drivers for this device worked OK but I read on some forums that OSSV4 had improved performance/capabilities. I came across this thread on the forums which I followed. (incloded removing pulse audio) Since then I have visited almost every forum/site I can find to try to resolve my issue. I have reinstalled pulseaudio and editied almost all of the conf files I could find relating to the xfi cards.
I was worried that I may have changed a config file that I shouldn't have. I removed all of the pulse audio apps using: su -c "yum remove alsa-plugins-pulseaudio pulseaudio padevchooser pavumeter paprefs pavucontrol" and also removed the config backups so that on a new install they would be replaced. I will post any information needed to resolve this issue, my goal is preferably not to use pulseaudio and successfully be able to use my 5.1 analog audio system I am sure that the system is able to see the card, but loading the driver / sound utilities is not working.

SOUND from analog Capture is out of sync in Pinnacle Studio 14.
[code]...
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'm using openSUSE 11.2 KDE on a Fujitsu-Siemens Amilo Pi 1536 laptop. My problem is that my microphone (I'm attempting to use a 3.5mm headset) doesn't work. Audio playback however does work through the built-in speakers and headphones.
I have gone through the SDB:AudioTroubleshooting - openSUSE as suggested by oldcpu on the Welcome to multimedia sub-area sticky.
I have tested audio recording with
Code:
arecord -vv -fdat foo.wav resulting in a silent recording. The vumeter showed 0% during the recording.
Here is my url produced by the alsa-info script:[URL]
rpm -qa '*alsa*'
Code:
alsa-plugins-1.0.21-3.3.i586
alsa-1.0.21-3.2.i586
alsa-oss-1.0.17-25.2.i586
alsa-devel-1.0.21-3.2.i586

I basically want to record audio streams. The most useful purpose is to record conversations on skype (and other applications). This is for a legitimate reason if anyone is worried; I often have long conference calls on skype (an another voip collaborative tool called EVO), and a recording would be a nice way to keep minutes and participate in the working meeting. I'm not worried about capturing video yet. The audio is the important for me for now. This is going to display my woeful ignorance of Linux audio systems. I'm running F12 x86_64 on a Dell inspiron laptop. I believe that the system is using the PulseAudio sound server.
I thought something like:
ffmpeg -f oss -i /dev/dsp sample.mp3
Could work, but I don't have a /dev/dsp. I think these are in a separate directory /dev/snd; however the content of this directory is not clear which device is the appropriate one. I tried pointing ffmpeg to a few of them, but it resulted in errors thus:
/dev/snd/hwC0D0: no such file or directory
I know it's there because [tab] complete. I found another alternative which uses parec.
parec --format=s16le --rate=44100 -channels=2 sample.raw
Unfortunately this only records the microphone input and not everything else going through my sound server. I wish I could find the link again, but there was a third alternative which required writing a bit of C code. I thought that could be a nice little project to better acquaint myself with this stuff.

I am fed up of listening to my (Windows XP) gaming computer through headphones so I want to get it hooked to the stereo.
Rather than use a heck of a lot of wire, I can sit my Ubuntu 9.10 netbook on top of the stereo and stream the audio across WiFi.
So, ideally what I am after is something to capture the outgoing audio on the Windows computer, stream it across the wifi to the Ubuntu netbook and finally play it through the speakers.

I could effortlessly set my output in Sound Preferences to be Analog 5.1. Now I just discovered that this option has disappeared, for no apparent reason. I haven't been messing around with any settings, other than installing updates as they've been rolled out. Would be nice to have 5.1 surround back as an option.

I finally decided to transition to a 64-bit install (AMD64). (same machine, just reinstalling as a 64-bit kernel starting w/ a Debian squeeze netinstall image) My audio chipset is nvidia MCP61, and it was working perfectly under a 32-bit kernel (I did the transition because a poorly-written system backup script (my fault) hosed /usr, /bin, and /sbin) When everything was up and running:
*: KDE4 only recognized the output device as ALC1200 Analog
*: kmix only had a single channel(master)
*: alsamixergui did recognize all the channels
*: some games (sauerbraten, for example) had no sound in KDE4.
*: some games (warzone2100, for example) did have sound in KDE4.
*: the games that had no sound in KDE4 did have sound in fluxbox.
I removed the following packages (some of which I had installed to try to get audio working properly):

I have an old Logitech Wingman analog joystick connected to a game port on a Creative sound card. At this point I've got the system to see the joystck and was able to run jscal. I was also able to run jstest. I was able to see positive & negative numbers moving the joystick in four directions. However, when I try 2 different MAME games or Open Arena there is no right direction. Pushing the joystick right only stops it from going left.. Up and down movement seems to be OK.

I picked up a Hauppauge WinTV HVR-1800 PCIe TV tuner a few days ago. Digital TV worked fine right out of the box (after setting up the firmware), but I have not been able to get analog video to work at all.If I run mplayer, xawtv or tvtime using /dev/video1 (yes, that is the correct devnode, video0 is a different card in my rig), So, has anyone RECENTLY gotten analog capture working on this card?

I am unable to get any audio to play. I configured alsa and checked to make sure nothing was muted. I think the problem might be KDE related but I'm not sure. Also when I restart the computer I get this error. "the audio playback device HDA intel (ALC887 Analog) does not work".

This plays fine in VLC, and there's a "Record" button there but I'm never prompted to save the recording anywhere. I wandered through preferences but didn't see any default capture directory fields.Where/how do I capture the stream for playback later? The docs that I've stumbled across so far are pretty outdated (but I'm still googling).

I need to capture from my webcam. It has a mic too.I can specify video input device as /dev/video0.I specified input audio device as /dev/dsp2 ( OSS device, corresponding to USB Webcam), Now VLC throws an error, "VLC is unable to open the MRL 'alsa:///dev/dsp2'. Check the log for details".Thinking it wants an alsa device, I specify device as /dev/snd/pcmC2D0c. (got it from kinfocenter and dolphin). Now again an error, "VLC is unable to open the MRL 'alsa:///dev/snd/pcmC2D0c'. Check the log for details.".I try with any device, the same error. I have added myself to audio device so that I can read/write to the mentioned devices.I see no way of switching VLC to use OSS. And I see no information (documentation on net) on it's expected device listing for audio.

I recently installed openSUSE 11.4-64bit on my Gateway desktop, and I can't seem to get my mic work at all. The mic is built into my Microsoft LifeCam Cinema webcam and works fine when I boot into Windows. The mic will not record sound in krecord or lame and doesn't work during Skype sessions.
According to the literature for the device driver my the mic should be supported, and that is evidenced by the fact that the mic shows up as a capture device in in kmix. I have made this mic the master channel under capture devices and I have given it highest preference amongst my capture devices in both the Communications and Accessibility categories of kmix's Settings/Audio Setup.
There was a very similar case solved in January:
How I got my Sound Input working
I've done my best to implement these fixes, but half of it looks like gibberish to me. All I was really able to do was update my alsa software and generate this comprehensive alsa.conf (its long, so I'll wait to post it until asked).
I've had since updating to 11.4, and I gotta say: I've been really impressed so far.

Running 10.4 Luci RC 64-bit desktop and when attempting to run Applications > Sound & video > Sound recorder, I receive the following error message:
Quote:
Your audio capture settings are invalid. Please correct them with the "Sound Preferences" under the System-Preferences menu. When I do go to System > Preferences > Input, there is only 1 device - "Internal Audio Analog Stereo" with no options for modification.My laptop does have an internal microphone but it apparently isn't working as nothing was recorded when I ran a Skype test call. This is the reason why I attempted to record something to check the mic.

I have this file:Code:vid-gd-19940626-peggy.rmI would like to extract the audio and copy to a file to burn on a CD.'pitivi' will load the file and show the audio timeline. But I can not find a save or copy button.'vlc' will play the file but I can not find how to seperate/save the audio.I found a 'ffmpeg' that is suppose to read whatever is being sent to your speakers.Code:ffmpeg -f oss -i /dev/dsp -f video4linux2 out.wavThis produce a file that 'mplayer', 'vlc', 'audacity' will load but it is empty of useful data. Black screen only.This is the second week I have worked on this. Either I'm googling for the wrong words or what I'm reading, I don't understand.

I'm looking for one or more command-line applications to capture and record some Internet audio streamings (Winamp, Windows Media and Real Audio type).For Winamp streamings I tried streamtuner and it works good, but it does not support Windows Media eal Audio streamings.I have to call the commands using the command line, because I need to use them in batch mode.

So I got myself a USB capture card (EasyCap) to use for capturing gaming, digitizing my kids' old VHS movies, etc. It works fine, I've been using VLC to view and record stuff from it, but I've noticed one issue. When recording streams via VLC, even with no other programs running to give VLC as much CPU time as it wants, the audio slowly falls out of sync. I've tried the MP4 (H264/MP3) container and the OGG (Vorbis/Theora) container.
Early on you can't hardly tell, but the further into a movie you get the more out of sync the audio gets, so that by the end of the movie the audio is a good 1-2 seconds off. It's not a set amount either so I can't just split the audio to a separate file then shift it one direction or the other to make up for the difference, because like I said, the offset starts out at nothing and gets progressively larger as the movie goes on. When I select "display locally", the video/audio that is displayed stays in sync, only the video/audio that gets committed to the output file falls out of sync, and it doesn't matter if I play the file with Totem or VLC.

I'm looking for configuring a Ubuntu box, we need to capture alsa output into ffmpeg with jack or OSS but not pulseaudio, as that tends to glitch badly. We have things working, but we are sort of hacking around in the dark, we play music, but as we aren't linux audio experts ourselves.

I have 4 video surveillance cameras with built-in microphones. The original VHS based recorder died and so I decided to build a PC based DVR for surveillance recording. Q-See will soon be shipping the QSPD4104 video/audio capture card that can capture both video and audio from 4 camera/microphone combos. (They also have the QSPD4114 with 16 a/v inputs) Is there surveillance software that can record both video and audio from multiple camera/microphone combos?

Im trying to create some screencast videos on Ubuntu. As its a well known fact we dont have a very good screencasting too like Camtasia(only windows) on linux.
After googling extensively I zeroed on Xvidcap for screen capturing and Audacity for audio capture.
According to tutorial [url] first we need to run Xvidcap (do the screen capturing recording first) and then again use Audacity for audio recording .. then mix both video and audio.
I guess this is a pain staking process (running video and audio recording seperately), I thought of running Xvidcap and Audacity simultaneously, if i do this xvicap works perfectly (video capturing happens) but audio capture through audacity does not work.
Note: I even try to run the above tools from seperate terminals/consoles (assuming they are seperate processes)
I even disabled 'audio' in xvidcap and tried to run both at the same time but audacity refuses to work.
I think both the tools are trying to use the same system resources ... and audacity is unable to get hold of the required resources.
Can we run both independently at the same time ?

every time I want to listen music from my headphones I have to do like:
1. Main menu >> System >> Preferences >> Sound >>> Output >>>> Connector >>>>> Analog Headphones
and vice versa.
I have no experience in bash scripting and I have no idea how to find automatic solution to my problem.
The problem in pseudo-code:
Begin
if
headset plugged in front jack
then Connector := Analog Headphones
else
Connector := Analog Output
End

I have just purchased this audio card. It is a common audio card for home studio musicians or wannabees. Pulse Audio uses the ICE1712 [Envy24] PCI Multi-Channel I/O Controller for this card. In the "Sound Preferences window the hardware selections are only variations of digital options. The gui (software) to control this card is the "Envy24 Control" which can be found in "Specialist tools for ALSA" package. With this package you have options to control the digital to analog conversions necessary.
I cannot active the analog inputs and outputs of this card. S/PDIF outs function but I can not use them to input to my Dynacord mixer.

I am currently using Fedora 11 KDE as my primary operating system at work, but i am having a little bit of troubles getting an audio player to work properly. I am trying to play music off of a separate primary FAT32 file system (which is my shared drive amongst all my operating systems), but when i attempt to load the files via JuK, i receive this error: cannot find demultiplexer plugin for MRL.
I have been playing around with other players as well, and it seems like the only other player which will actually load up the media on this separate partition is Banshee, but doesn't seem to want to play it.
