Programming :: Obtain The Audio Stream That Hear In Speaker System Or In Earphones?
Sep 26, 2010
Let assume that we have the following situation: we have a sound in the speaker systems or in earphones, maybe we play an audio CD, some mp3's or maybe a movie, etc.
All I know is that the sound goes through sound card to speaker system or in earphones, no matter the source.
How can I obtain the audio stream that I hear in speaker system or in earphones?
I would like to write an application that record and analyze the audio stream that I hear in my speaker system or in earphones. My OS is Ubuntu 10.04.
If you have a recommendation like "try to use ALSA", please provide more details like "in alsa-utils you have a class Class_Name, with the following function Funcation1, etc. Try to use the Function5 as in the following example".

In the current release of Debian, is there a reason that I can only hear sound through one speaker. With any other distro, the sound can be heard through both.

Yesterday I installed openSUSE 11.3 on a desktop PC and I noticed that the PC's speaker it's not functioning but if I plug the headphones I can hear the sound system working.

How's the quality of the sound that gets to your loudspeakers? What components do you have - brand, specs, mode and distance of computer to amplifier?[URL].. Mid and bass sound good.

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.

One issue that I'm having with Fedora that's stopping me from dropping Windows altogether is that I can't seem to get my audio in line to play directly to my speakers.
Basically, I've got my games console set up so that it uses the desktop computer's speakers as audio output, and is also plugged in to the same monitor and I can change the source depending on what I want to use it for.
I know the hardware works, as the whole thing works fine when using Windows (XP SP3), and I can still record from the audio in line using Fedora (so I can record me playing the game, then play it back and hear it through the speakers), but I've got no idea as to how to redirect the game sounds directly to the speakers.
Interestingly, every tutorial I've found so far suggests that the opposite should be the problem, and that the situation that I want to be in should be enabled by default. That said, I've been tinkering with the audio packages and whatnot long before I tried using the machine for gaming, so maybe I managed to inadvertently remove a package some time ago.

I have f13 installed in my system.My problem is ,i can hear sound thro' my desktop speakers but not with my audio headset. I have tried in many ways to fix it , by reinstalling pulse audio , installing ALSA etc But failed. In my system menu bar -- in preferences sub menu-- there is no " ADVANCED AUDIO CONTROL" available to edit sound output. similarly i am not able to use the mic of the headphone.

I've installed a tv card but I can't hear the sound through my built-in CMedia soundcard when I watch tv with TVTime. The tv card's audio output is externally connected to my soundcard's line in input. In the 'Input' tab of the 'Sound Preferences' dialog, I can see the input level meter moving.
Audacity can record the tv sound, and I can hear it when I have the 'pass-through' option enabled, or when I play the recording.
I can play media files without a problem, and I can hear the system sounds.
But for some reason I can't get the tv sound to go through to the soundcard's output.
Obviously I've got the audio configured wrong, but I don't know what to do to fix it.

When I run the audio configuration I get:
The following audio device was detected:
Vendor: nVidia
Model Coporation GF100 High Definition Audio Controller
Module snd-hda-intel
but I do not hear sound.
The ALSA driver version is 1.0.14rc3
Lib package is: 1.0.17.-1.e15
Utils package is: 1.0.17-1.e15
The sound log has:
class: AUDIO
bus: PCI
detached: 0
driver: snd-hda-intel
desc: "nVidia Corporation GF100 High Definition Audio Controller" .....
The audio configuration sound test and the answer to the question No returns a message that says: automatic detection of sound card did not work. I am not sure what else is needed to diagnose the problem.

My workstation has a built-in speaker that, surprisingly, plays audio very well. I also have external speakers hooked up to the audio out jack which are easier to hear. Unfortunately, when I try to play some audio material, sound comes out of both the external speakers and the built-in speaker on the workstation.
I'd like to disable the speaker inside the machine, and just plug in head-phones to the external speaker so I can listen to training material at work without bothering my office mate. I'm not sure how to do this in Linux (Suse Enterprise Desktop 11). Fiddling around with the Gnome audio tools doesn't list two different audio devices on the machine.
From what I can tell, sound is played through the ALSA system. I looked in my home directory and there is no .asoundrc controlling configuration.
I should also add that I check in the BIOS for a way to disable the built-in speaker, but I could not find such a setting.

I installed Xubuntu to a flashdrive using unetbootin. Since I only have a 2GB drive I installed Fluxbox instead of XFCE to save space. I install alsa-utils to try to get some audio going. aplay and speaker-test gets nothing at all. Both as sudo and a reg user. I have turn up the volume on everything in alsamixer. I believe the relevant drivers are loaded.

We have remote offices and we'd like all announcements in one office to stream to the other offices, to play on the speakers connected to VLC machines there. We can stream audio with VLC when working with a file, but how would we stream all audio produced by a single machine?
Ideally this would stream anything coming in from AUX/Line-In jack, as well as any other sound that the computer would make. I'd prefer to use cvlc (CLI version) rather than the GUI VLC, but whatever I can get would be good.We can run either Debian 5.0.x Lenny with 0.8.6.h-4+lenny2, or Debian 6.0.x Squeeze with 1.1.3-1squeeze2

I'm running Ubuntu 9.10 (Karmic Koala) with Skype, and I can't get the microphone to work. I can hear them, but they can't hear me. I tried the same headset with my Windows system, and it works fine, so the headset is OK.
I looked at "Sound Preferences", and noticed that when I click on the "Input" tab, the area where you can adjust the volume is set at the minimum, and grayed out, so I can't adjust it.

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've used VLC for years, in both windows and linux. In windows streaming, you can select "NONE" for a Video Input, and just stream audio. This is not the case for Ubuntu's version.What can I do to stream just audio in VLC?

im creatind dvd's from others hd movies and ive seen theres an option to adjust framerate in audio, but ive never using that and i dont see the difference, when i play the video i see audio is syncronized with the video.for example, for a movie with 23,97 fps i converted to PAL (25fps) and i dont do anything to the audio, and it plays sicnronized then ¿Its neccesary to sync audio, and how its done with ffmpeg?
i do somethin like this: ffmpeg -i source.mkv -target pal-dvd -acodec copy mydvd.mpg (is audio fps syncronized because of the target?)if i dont use target, should is use sb like this?.: ffmpeg - i source.mkv -r 25 -vcodec mpeg2video -acodec ac3 -r 25 output.mpg

I have two networked Ubuntu 10.40 machines and I am trying to stream audio from one machine to the other. I find on the surface everything works - I simply installed padevchooser and set the pulseaudio sink to the other machine. Now here comes the problem - whenever I do anything else involving network activity the sound crackles and hangs and it becomes hopeless. I've seen people elsewhere online complaining about crackling in relation to CPU usage but I can't find anyone talking about network usage.
In particular I often work on my office computers over VNC. I try to fire up VNC and it starts to load the remote desktop and the sound completely fails. I assume this is some kind of latency issue? Another good example is trying to watch a video on ..... - the sound plays at first but then as the video is being downloading in the background the stream starts to mess up. Listening to an mp3 in totem with no other network activity works fine.
