I can't get arecord to record any sound. I've tried running firefox with some streaming stuff or even just playing a song with totem from a mp3 on my hard drive. I'm running
Code:
But the resulting test.wav has no sound in it.
I'm running maverick as installed. What gives?
I'm completely new to ALSA and I'm having trouble using the arecord program.
Using the following command: arecord -t wav -f cd -d 5 test.wav
Creates a .wav file 5 seconds long as expected.
However when playing this file there is no sound.
I've had a look using 'alsamixer' and the capture volume is over half way so I'm assuming it's not that.
I just upgraded from 8.10 to 9.04, then rapidly to 9.10, when support for 8.10 was finally phased out. I've been trying for a few days to figure out how to record sound and can't get anything working. Sound playback works fine.
Here's what I've tried so far:
Code:
The terminal programs execute and quit after ten seconds, as expected, and create a sound of the appropriate length in my home directory, which is what I want. They don't report any errors, but the sound file they create is just soft background static with occasional soft clicks. Audacity also just records soft static with soft occasional clicks. The Gnome Sound recorder does slightly better, recording almost-intelligible sounds with bad static distortion.
I've verified that sound levels are not muted using the mixer, and have run through the Comprehensive Sound Problem Solutions Guide [url]. No joy.
Here's the output of lscpi -v:

View 4 Replies View RelatedIs there currently any way to record a webcam video with sound? This used to be possible back in the day before PulseAudio was installed by default (by using Mencoder, following guides such as [URL] and [URL] ) but that method doesn't work any more: /dev/dsp doesn't exist. I've also tried Cheese and that again just records a video with no audio. All the articles I can find on the topic are from the good old pre-Pulse days.
I've tried messing about with the commands a bit to use the Alsa Pulse device (defined in /etc/asound.conf) since neither mencoder or ffmpeg seem to have built in Pulse input support:
Code:
ffmpeg -f alsa -i pulse -f video4linux2 -s 640x480 -i /dev/video0 out.mpg
- this works, but the audio is more than a second out of sync with the video, which is a bit useless (I'm trying to record myself playing guitar), and the video is very slow (<1 fps) for the first few seconds.
Code:
mencoder tv:// -tv driver=v4l2:width=640:height=480:device=/dev/video0:fps=30:forceaudio:alsa:adevice=pulse -ovc lavc -oac mp3lame -lameopts cbr:br=64:mode=3 -o test.avi

View 9 Replies View RelatedI was, untill very recently, using ubuntu 10.10, and have just upgraded. In Ubuntu 10.10, I was easily able to record sound from my sound card in audacity. For whatever reason, since upgrading I have been unable to do so. I have no problem recording sound from my laptop's microphone, but can't seem to find an option to record from the sound card. I believe it's the same version of Audacity, so all I can assume is that it's an Ubuntu issue.

I found that Mike Oldfield "Tr3s Lunas" being played backward (from the end to begining) is an addictive, magic music. For this I used alsaplayer. Now I want to record these reversed music, not everyone player is able to play backward, how I can do that?
Now I am using some kind of a mutant ubuntu, say version between 9.10 an 10.04, with gnome desktop and alsa sound system.
I currently have pclinuxos 2007 (updated to kde4). I put on webinars, and like to record them using recordmydesktop. All is working fine by putting a splitter in my speaker out, and feeding it back into my line in. This only works when I have analog loopback not muted.My problem is that pclinuxos is now putting out there 2010 version, and there is no way I can see to un-mute the analog loopback. It does not show up as any options onkmix.... I am going to attach a couple pictures one with my old kmix, and one with the new 2010 version.My question is, how can I get back that analog loopback, or is there another way to get the sound to record from both my speaker and my mic?
View 14 Replies View RelatedI have input the sound from my TVcard into the line-in port of my soundcard. In VLC, I could view TV signal with both video and sound but when i click on "record"it only records video without the sound at all. When I view this in pulseaudio volume control, under the recording tab, there seems to be no application taking over when I click on record button under VLC. Yet if I start up gnome-recorder, I could capture the sound when I view TV with VLC and clearly under pulseaudio volume control I see recording application is that of gnome-recorder. What's the deal here? How could I make sure under VLC it will record the sound?

View 2 Replies View RelatedI've got sound - I hear all the system sounds, I can play sound files, CDs, etc. But I have not been able to record and play back anything with success.
Originally, when I would record (either with arecord or with audacity) I would get extremely low quality sound, with lots of noise and crackling, and my recorded voice was barely audible (even with volume turned up to max). I played with alsamixer for hours without being able to improve matters.
Things are worse now. I tried installing alsa-firmware, as indicated at SDB:Audio troubleshooting - openSUSE. I also tried updating alsa following instructions given at SDB:Alsa-update - openSUSE. I'm not sure which of these changes did it, but the result is that I can no longer record ANYTHING at all. I get absolutely nothing, not even the low quality noise and crackling I was getting before. It's as if there is no audio input at all.
Uninstalling alsa-firmware and reverting back to the older alsa version (1.0.20) didn't change a thing.
I'm running openSUSE 11.2, kernel 2.6.31.14-0.6-desktop, alsa 1.0.20. My sound card is a Creative X-Fi (by the way, yast cannot detect my card, another problem I have never solved).

I've found somewhere on the forum I need to check whether "wave" in alsamixer is not muted. There is another posibility: change source in audacity to "wave". There is no option like this in my program and I don't know where can I find that "wave" in alsamixer. I don't use any like artsd, jack... Just alsa + fluxbox + audacity.
