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 put in a dvd and couldnt hear the first 3 minutes of one dvd, i put in a second dvd and could hear anything from it, how do i know what codecs to install to hear the audio? the video is viewable
I got an audio disc to play in kaffeine but not in amorok, in setting of amarok i hit the configure phonon and pick my audio device hit test and i can hear sounds.
i installed opensuse10.2 on my lenovo machine.it is intel core2duo processor,hitachi hard disk ,1 GB ram , 1.80 GHz. in which i unable to hear audio . default audio driver installed on my machine is 82801G (ICH7 Family) High Definition Audio Controller and Driver snd-hda-intel . ply help how to hear audio on my machine
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 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.
Through the command prompt, mainly wav files, wanted to see if there is any way to get this done?That would be the pc speaker on the board, I can get it to beep at frequencies.
I have installed Skype 2.1 (Beta) in linuxmint Julia, now when I am communicating with anyone or video conferencing, I am able to hear the other person but the other person is unable to hear my voice, I talked with someone else who is facing the same problem in Ubuntu.
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.
So sound from the speakers on my laptop (hp mini 311) quit working randomly. I either installed an update or just rebooted and it quit working. The sound from the headphone port still works but that is annoying.
Here is some information about my hardware. Code: *-multimedia description: Audio device product: MCP79 High Definition Audio vendor: nVidia Corporation physical id: 8 bus info: pci@0000:00:08.0 version: b1 width: 32 bits clock: 66MHz capabilities: pm bus_master cap_list configuration: driver=HDA Intel latency=0 maxlatency=5 mingnt=2 resources: irq:23 memory:d3100000-d3103fff
I Tried to play video files (.avi & .vob) in Kaffeine, but was unableo hear any audio. Then i went to the packmn site and installed the packageom there, with no positive results.After that i installed VLC and then tried playing.
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.
I have a Acer emachine E732z laptop. I have installed debian squeeze gnome, but it is unable to play audio through laptop speaker. The (3.5mm)audio jack is working fine and I can play audio through it. I have also installed Linux mint, but no audio(in speaker and audio jack). There is no such problem in Windows7.
How might i be able to play a small blip/beep sound to let me hear/test the audio levels upon volume change? Mac OSX users may know what I'm talking about. I had a similar application in windows. It helps me guage my volumes before i play games/...../videos.
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?
i'm using ubuntu 10.04 64bit and i have a netbook(model is hp mini 110-3004TU) with an integrated HD audio from IDT.the problem is that no sound is coming out from the speaker
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.
