I've already patched the iSight firmware, so the the webcam itself works fine, but I have no microphone support. If I go to Sound Recorder, the microphone picks up my voice fine, but not Skype.

I can get audio through my microphone into ubuntu and can record into audacity without a problem, however, I do not know how to get JACK to recognize the audio from the microphone (through the normal mic jack)... any ideas how I may accomplish this so I don't need to do all kinds of file conversions and imports to set down a vocal track with the tracks I record (via USB) through JACK?
View 3 Replies View RelatedI am trying to record audio playback from an application and the microphone at the same time on recordmydesktop using pulse audio. I just can't figure out how to mix them both. I have tried a lot already and can only get either the mic or the audio playback to be recorded, not both. Can this be done using pavucontroll?
I have been search now for hours to find a solution (also here on the forum) for this and getting really frustrated now. Maybe i'm just missing something really obvious, so sorry if this is a stupid question.
Is it possible to pipe audio from espeak into a microphone device?
I've tried doing
Code:
sudo espeak --stdout "Hello world." >> /dev/audio
but I just get:
Code:
bash: /dev/audio: Device or resource busy
how can I adjust the volume level while recording audio playback and microphone at the same time? I managed to increase the audio playback volume with PulseAudio Volume Control (Input devices -> Monitor of Internal Audio Analog Stereo -> pressing green button "Set as fallback"), but once I click on that green button, no no microphone sound is recorded.
Details:
- using Ubuntu 10.04 LTS
- recording audio with Sound Recorder
- installed PulseAudio Device Choooser and PulseAudio Volume Control
- Input devices -> Internal Audio Analog Stereo --> shows the sound from microphone

- how to adjust volume of audioplayback and microphone recording and record both as a mix together? Thanks!
PS: I checked out this thread, but haven't figured out how to adjust the volumes.
First off, this isn't the usual "physical" feedback of a speaker being too close to the mic. This mic is part of a headset so there's no way for the output and input to overlap and cause feedback. This mic has worked perfectly for me in the past, but I recently re-installed my OS and it hasn't worked since.
It seems as if my audio out is getting redirected to microphone in. If I open up and sound recording program while I have some audio being output, the output will get echoed back in through the microphone channel, although any actual microphone input is never picked up. I can blow or scream into the mic and there's no indication at all that Linux is picking it up.
I'm running ArchLinux with ALSA. I've gone into alsa mixer and played with just about every channel in every way I can think of, and none of the options seem to fix the problem.
How should I fix this? I use my mic pretty much constantly when I'm on the computer, being without it sucks.

View 1 Replies View RelatedI have some microphone problems. I can't record anything. (I'm using openSUSE 11.3)
My sound card was detected almost correctly (at least the chip-set was i think). I have an Asrock motherboard (k7upgrade880, with a Southbridge: VIA 8237 | Audio: CMedia CMI9761 6 channel AC'97.
I ran these commands so far with these results - while i was following the audio troubleshooting guide (SDB:Audio troubleshooting - openSUSE
But i have NO audio playback problems - movies, games, music all play well. And the Microphone guid has a broken link
I tried to change my 50-sound.conf file (i read it on a forum, I'm new to linux troubleshooting) from this:
options snd slots=snd-via82xx to this: options snd slots=snd-via82xx position_fix=1
But that did not work either. I did not get any sound with the last line.
i just upgraded from Skype 2.0.0.72 to 2.1.047. Now my microphone isn't working anymore and i cannot select it in the skype options. From now on i can only select the PulseAudio server ..
So i have read some howtos for PulseAudio. They say i should starte PulseAudio Volume Control. ok.. Now i should go to the tab "Recording". This tab doesnt exist on my pc. I upgraded to the latest version of this volume control. It still doesnt exist.
I am using OpenSuse 11.0 with KDE4.3
Here are some screenshots:

PS: My mic is still working with applications, that dont use pulseaudio.
Can i find sample program to record audio through microphone connected to PC.

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.

In the menue of Kubuntu 10.10 (live-CD) for selecting the keyboard layouts
appears a message saying that there is a limit of selecting maximum four keyboard layouts, if I try to select a fifth one. That is very little four people involved/dealing with languages or for computers shared by several people from different countries. Does anybody knows anything about this limit and how to increase this number? In windows you can select more than a dozen languages. Where is the problem? Is it a problem of the KDE or of the linux kernel or what kind of problem is it? An other user told that this problem exists also in other versions e.g. in Ubuntu.

View 2 Replies View RelatedI'm trying to build boost on a 64-bit CentOS 5.4 install. I have Python 2.6.4 built and installed at /opt/Python_2.6.4/, and I've appended the user-config.jam file with:
using python : 2.6 : /opt/Python_2.6.4/python : /opt/Python_2.6.4/Include : /opt/Python_2.6.4/Lib ;
The standard system Python is 2.4.1 but the tools I'm using require 2.6, so I've built this version and installed it independently of the system version 2.4.1 to avoid any conflicts.
As I'm sure you've already imagined, I get the error:
LONG_BIT definition appears wrong for platform (bad gcc/glibc config?)
I see that this is a long standing bug, but I have yet to find a fix. I've tried various CCFLAGS, CXXFLAGS, etc. to push for a 64-bit compile or a 32-bit compile (-m64 or -m32).
The offending file is pyport.h - is there a 64-bit friendly version that I don't know about?
how do I install boost 1.44? The whole time I have something wrong .. how I install?

1. When I do "rpm -q boost", it shows boost-1.33.1-10.el5. Why is that so, when I've installed version 1.44? Did I have to remove the existing rpm before building the new version of boost?

As governments around the world amass armies of hackers to protect their countries' computer networks and possibly attack others, the idea of getting officials together to discuss shared threats such as cybercrime is challenging.
"You just don't pick up the phone and call your counterparts in these countries," said retired Lt. Gen. Harry Raduege Jr., former head of the federal agency responsible for securing the military's and the president's communications technologies. "They're always guarded in those areas, and they're always wondering if there's some other motive" behind the outreach.
So the idea behind an international security conference in Dallas this week is to get government officials, industry executives and others talking, informally, about where they might find common ground.
