Ubuntu Multimedia :: Find Out Microphone Device Under /dev/?
Jan 16, 2011
I have this software I want to use to extract data from a Polar heart rate monitor. Everything related to sound is working flawlessly. I just need to know the device name of the front microphone ("microphone" 2" in sound properties) so that I can insert it in the following cli command for a script: "rs200_decode -m /dev/XXX -b -o /home/user/dumb.bin"
I checked the forums but I only see references to /dev/dsp, /dev/audio, etc. I don't have any of those but rather /dev/snd/controlC0, hwC0D2, pcmC0D0c, pcmC0D0p, pcmC0D1p and pcmC0D2c.
I'm using Ubuntu 10.10 32-bit. The sound card is a generic HDA Intel audio chip. Lspci outputs: Audio device: Intel Corporation 82801JI (ICH10 Family) HD Audio Controller.

but I just get:
Code:
bash: /dev/audio: Device or resource busy

Everything works outside of Skype. Speakers work in Skype, but the microphone stays dead. I've dumped Pulseaudio, made sure volume is up in Alsa, rebooted, but Skype still lists Pulseaudio as what it's using! How do I get its tiny mind to use something else? There was also a thread saying an earlier version of Skype, 2.1.0.47, used to work, but I can't find a 64-bit version of that. I've got the 32-bit version which I could run in a 32-bit ubuntu in virtualbox, but fergawdssake there has to be a better way!How do I make sure the system isn't still somehow using Pulseaudio? I did purge it. It should be gone. Output of various system specs:
Code:
uname -a
Linux bunty 2.6.32-23-generic #37-Ubuntu SMP Fri Jun 11 08:03:28 UTC 2010 x86_64 GNU/Linux

I've bought an X10 Home Automation USB interface: the CM15.
This is the information lsusb gives:
skerit@KIP-DU-SKER:~$ lsusb Bus 008 Device 002: ID 0bc7:0001 X10 Wireless Technology, Inc. ActiveHome (ACPI-compliant)
But this tells me nothing about where the device file is! How can I find that, or create one myself?

Recently, I created a device sc0 through device mapper. The divice could be found in /dev/mapper/sc0. My problem is that the device doesn't exist in /dev/partitions which will block my following test.BTW, I found dm-0 in /dev/partitions. Is it the same as /dev/mapper/sc0? But the device /dev/dm-0 doesn't exist!

I have a Toshiba Satellite A100 I am using 10.10 I am using headphone/microphone headset this did work for me with 10.04 never a problem, I have tried to use these to fix problem - audacity/sound recorder/pulse audio volume control/pulse audio device chooser/ (the more I use 10.10 the more I love it its been a learning curve I am sure this is just another one of them for me..)
Re: Microphone not working after upgrade to Ubuntu 10.10 Maverick My hardware profile is Duplex. When I click on the input tab the signal measuring bar is always staying lit on the first section and does not move further. This means that the mic is not capturing sound. In 10.04.1 there was a dropdown menu in the input tab from which I could choose the default microphone and thus choose an option that works. In 10.10 there is no such thing. I kind of fixed it by adding "options snd-hda-intel model=3stack" in alsa-base.conf. Now I have the dropdown menu and my microphone works for now. The problem is that I did not have to do this in 10.04.1 ... options snd-hda-intel model=3stack sudo gedit /etc/modprobe.d/alsa-base.conf for mine it was mic 1 and it worked

I just compiled my first own kernel (I'm using Arch Linux), following the tutorial on the german site. Now I tried to boot it, I ended up failing with this message: Code: Waiting 10 seconds for device /dev/sda1 ... Root device '/dev/sda1' doesn't exist, Attempting to create it. ERROR: Unable to determine major/minor number of root device '/dev/sda1' Here is the important part of my menu.lst:
[Code]....
I simply copy&pasted the Arch-entry, i.e. I also had the disk by uuid there. The failure message was the same, just the root device name was the different name Also, at first I did not have the initrd line in my menu.lst (as written in my tutorial that I may not need it). In this case I had this error message:

I've got 9.10 installed on a dual boot T-43 Thinkpad.The Thinkpad has a built-in microphone which is driving me crazy. I have a pair of outboard Sony speakers sitting on my desk & the sound of the fan and every keystroke is picked up by the mic and amplified back at me through the speakers. If I turn the volume on the speakers up more than about half way the mic picks up the feedback I get a high pitched squeal through the speakers.I've gone into "Sound Preferences" and muted "Input Volume," but it has no effect - the mic is still picking up and amplifying every keystroke & giving me feedback.How can I turn off the damn mic? (by the way, I do not have this problem if I boot into XP)

I can't seem to get my microphone to work on Ubuntu 10.04. I have a Creative Sound Blaster Audigy SE PCI sound card. [URL]... Sound card is recognized by System/Preferences/Sound/Hardware as CA0106 Sound Blaster 1 Output / 1 Input Analog Stereo Duplex And sound output works 100% perfectly. I Google'd for hours and did not see anything to fix my microphone. My computer has front headphone and microphone ports and the front headphone port works fine but microphone does not. Also I tried plugging microphone into all the ports on the back into sound card but none worked. Also, I ran alsamixer from terminal and maxed out all volume settings. I wish to get the microphone working so I can play Counter Strike Source with Wine. I am willing to buy another sound card if someone can point out a replacement.

At some point i probably messed up my sound configuration, and now i cant record anymore.
What works : * I have pulseaudio, i can play sound from several apps simultaneously, eg : mpd + vlc + firefox + skype
Remarks :
* pulse-audio is as system-wide installed.
* I have installed linux-backports-modules-alsa-2.6.32-26-generic
* I have 1 internal sound card (on the main board) + 1 ATI graphic card with HDMI output (and thus a sound chip)
* I have 2 output-plugs (1 normal + 1 headphone)
* I have 3 inputs (2 microphones + 1 line in)
* In the past, i installed a PCI sound card, for testing. It may remains old configuration files related to it.
THE PROBLEMS :
* I can not record. In the Pulse-applet / Volume control, in the tab "recording", in the tab "input device" (i translate from french), i can choose between mic1, mic2 and line in, but none of them has any effect on the volume meter.
* In the the tab "configuration", there is no sound card listed, just the message "no car available for configuration" ... that might show that smthg is wrong ! Notice that in the past (but still under lucid), it used to work. There was here all the cards (internal + HDMI video card) listed.
Output of alsa-info.sh :

I can't seem to get my microphone working. All the levels are maxed, nothing is muted. I've checked pavucontrol, alsamixer, and sytem-preferences-sound, but according to all that, there is nothing muted, and all the levels are maxed. I'm running ubuntu 10.04. My mic works fine in Windows vista, but not in Ubuntu. I am thinking I may need to update my drivers or something. Also I've gone over the forums but haven't found a solution that works, many of them involve changing the levels in system-preferences-sound, but again, that doesn't work. I've posted the results of aplay -l [URL].

I have a Dell Dimension 9200 (DXP061) with a Create eXtreme Music card. The box has a front mic jack and I can't get that to work.In the "Sound Preferences", it shows two possible hardware sources: "Internal Audio" and "SB X-fi".In "Input" I have multiple choices for "Connector" when "Internal Audio analog stereo is selected" ("Microphone 1/Line-In" etc) and for "SB X-Fi Analog Mono" there are none.I have tried every combination in there, plus every combination I can think of in "alsamixer" and the microphone still does not work (I know the microphone itself is OK).

I'm using Kubuntu 10.04. I've got a Samson Q1U usb microphone I want to use in Audacity for recording.
Unfortunatly, the microphone isn't registering on my computer.
I can use a usb mouse on the usb port, so I think the port works and the microphone worked on my friends PC, so the mic is fine.
When I plug it in the light on the microphone goes on for about 10 seconds then goes off.
Here's some output:
And the following, showing my ports:
The microphone is not showing up on either...
I was using the microphone fine a couple years ago with audacity, I think I was on Hardy Heron at the time (not that the upgrade to lucid was necessarily was what did it...) I haven't changed any hardware since then besides adding a little additional ram.

I'm running Ubuntu 9.10 on an Asus F3JC laptop with an integrated webcam and microphone. The webcam is a
Code:
user@ubuntu:~$ lsusb
Bus 001 Device 004: ID 05e1:0501 Syntek Semiconductor Co., Ltd DC-1125 WebCam
and it works. If i tap on the microphone or if I blow on it, I hear noises but after I record something with gnome-sound-recorder I don't hear any sound! The same with Skype, for example.
On Xp (other hd partition) it works.
The audio device on the laptop is a

user@ubuntu:~$ aplay -l

Subdevices: 1/1

If I open the "sound preferences tool" the device for sound input is "Internal Audio Analog Stereo" and even if I tune the volume of the microphone I don't see any movement in the input level bar. I've also checked alsamixer and the digital volum in the capture interface is set at the maximum.

I've been trying to get my webcam microphone working in flash on Kubuntu 9.10.I have a Logitek Pro 9000, and video and audio work in other applications (skype), but video is all that works in flash (I have flash 10 installed). In the flash settings, it lists the only microphone option as "Linux Microphone", which does nothing. This seems to be a common problem, with a few solutions offered.
One I've tried, which seems fairly straightforward for gnome users, is here. However, whenever I run pavucontrol, I get an error reading "Connection failed: Connection refused".Does anyone know how to either get pulseaudio open, or how to get the microphone working in flash without it?

It's been almost two months since this problem started. I'm running 9.10, Karmic Koala, with all updates. I was hoping one of the updates would just fix this problem.
The microphone does not appear to work at all. It seems to exist because I have a choice for "Internal Audio Analog Stereo" under "sound preferences," but I don't know how else to check whether this is true. Sound Recorder does not record anything and Skype does not capture any sound from me.
how to run commands in the terminal and I consider myself an intermediate user, I just don't know anything about sound.

I've been having problems setting up my microphone and webcam for internet use. I won a Microsoft LifeCam VX-6000 on the internet and it doesn't work on ubuntu. I'm sure it works because I also have Windows Vista installed on my laptop and it works perfectly well when using Skype, Windows Live Messenger and even Gtalk.
This webcam model has an integrated microphone, which doesn't work either, even though it works just fine on Windows. I have tried to configure the mic, but when I test-record the sound all I can hear is just noise. I have test-recorded using a headset (which also works on Windows), but I didn't have any success, so I have to believe that I haven't configured something the way it was supposed to be or that a driver is missing.

I need a simple program that I can talk into a microphone and the sound will come out the speakers. I want to use my Computer that's hooked up to the store speakers as a PA System.
I am having a difficult time finding a program that will let me do this without having to record and playback. Any help would be wonderful.

I go to System>Preferences>Sound>Input. The setting, that I had previously placed at 50 %, is now at 10 %. I try to drag it with the mouse but it refuses to move. I have to hang up the communication and then take it back to 50 %. After I call again, we can talk OK. What can I do to correct this trouble? I am using Ubuntu 10.04 LTS - the Lucid Lynx - released in April 2010.

I use Ubuntu 10.04 but I had this problem in 9.10 too.
I have a problem regarding my sound preferences. I have a microphone and I want to use it to make calls. The problem is that when I speak into the microphone when a program like Skype is used, my sound suddenly crashes(The microphone won't take any input nor will I hear any sound from the speakers if I play a video or music. This gets fixed if I restart the computer). This also happens if I go to Sound preferences → Input or Output and edit something there.
If I don't make any of the above, the sound works just fine as I can listen to music and play videos.
I don't know much about computer hardware but here is some info about my sound card:
Code:
VIA Technologies, Inc. VT1708/A[Azalia HDAC] (VIA High Definifion Audio Controller) (rev 10)
Subsystem: Biostar Microtech Int'l Corp Device 820f

I converted my parents to use Ubuntu on their laptop, and they seem to like it. One minor issue though is that the microphone input preference keeps reverting, so every time they want to use an internet phone, they have to reset it manually by going to System/Preferences/Sound/Input and choosing the external USB microphone. Then they can launch the phone program (Skype in this case, but it doesn't matter which one.) My Dad asked me that he doesn't have to do this on Windows so why does he have to with Ubuntu? I am hoping there is a way for me to fix it so he doesn't have to. (We don't have a microphone that plugs into the "internal audio analog stereo" line.)
When they finish talking, they unplug the external microphone and this is when the preference seems to revert to the "internal audio analog stereo" setting, which makes sense, but when the external microphone gets plugged back in, it would be great if it "remembered" it. Is there a way to make this happen automatically?
