Ubuntu :: 10.4 RC - Your Audio Capture Settings Are Invalid
Apr 24, 2010
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 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 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.

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 The docs that I've stumbled across so far are pretty outdated (but I'm still googling).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 want to record some streaming internet radio talk shows and music performances on NPR, and I'm wondering what my options are in Ubuntu. I'm looking for something that can output high quality lossless files in several formats, hopefully including mp3 and ogg.

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'm running Ubuntu 11.04 on a Compaq Presario CQ62, with factory specs. I have downloaded and installed VirtualBox 4.1.0 r73009, and successfully installed Windows XP SP3 and Windows 7. However, I have now hit a problem. When I go to Settings for either virtual machine, I get an error that says "Invalid settings detected". It doesn't matter what I try to change or adjust, this message will not disappear. I do not currently have USB support for the Virtual machines, but it's not a big concern to me at this time. I don't know what commands I need to issue or what information I can offer to get the readout of what's not working right. I am very comfortable using Terminal, but have no idea what to look for or where to go.

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 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.

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 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 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 ?

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
[Code].....

I've purchased Creative sound blaster. It's external usb sound card, which worked well as I plugged it in. In sound preferences it was setted to 'Analog stereo output' in hardware, and I've accidently messed up with Connector droplist in Output bookmark. As a result - silence in my speakers. I wonder what went wrong and where to search for it. The card is worked and it is supported by ALSA. Just some settings went wrong.

I've recently encountered a sound issue and I recently installed the nvidia gt220 in my box and was thrilled at how well it worked with hdmi until I tried to use the audio. I updated my alsa and went into the alsamixer and it does detect my gt220. I unmuted all spdif and tested the sound and with success the sound test works. I know the card and device numbers that work with the audio but now sure where to make changes so it will default to that device instead of the onboard audio that it seems to try to use now. I am running lucid 10.04.

I have three audio devices on my system;
1. a builtin (broken)
2. an HDMI on my graphics board
3. a USB audio device (i am using this one)
I normally shut off the system each night. Next day, I have to go through the pulse-audio mixer and re-set all of the audio settings. They are apparently not being saved. I've searched the forum for 'save audio' and similar terms but no joy.

Mencoder settings... I'm doing a simple transcoding of an avi file from FFmpeg MPEG4 codec to XVID MPEG-4 codec. The problem is that the audio bitrate is changing from 192 kbps to 32 kbps. The audio codec for both files is mp3 (MPEG-1 layer 3). (I'm transcoding the FFmpeg MPEG4 encoded avi because my blu-ray player doesn't see, let alone play it. Any XVID MPEG-4 encoded avi files the blu-ray player sees and plays fine). I ran mencoder trying the four settings below but the audio bitrate still comes out at 32 kbps:
Code:
mencoder camping_en.avi -ovc xvid -oac mp3lame -xvidencopts bitrate=192 -o camping_us.avi
mencoder camping_en.avi -ovc xvid -oac mp3lame -xvidencopts bitrate=687 -o camping_us.avi
mencoder camping_en.avi -ovc xvid -oac mp3lame -xvidencopts bitrate=9146 -o camping_us.avi
mencoder camping_en.avi -ovc xvid -oac mp3lame -xvidencopts bitrate=192000 -o camping_us.avi
How to keep the bitrate at 192 kbps?

I'm still working on ubuntu 9.10 with an acer aspire 1810tz. To use my microphone I found out that I have to change my microphone settings because it's mono and the default setting is thinking it's stereo: With the Volume Controller I setup one chancel to 5 and the other to 90 and the mic is working fine. Starting Skype and using it I see that the setting is reducing the volume for the mic below 20, so nobody can hear me. I tried closing first Volume Controller and then starting Skype, no matter the volume of the mic is reduced. How do I stop this behavior?
