Fixing the Errant Microphone December 5, 2005
Posted by Carthik in ubuntu.trackback
The microphone on my laptop wasn’t working too good, and I found a quickie guide to help fix this. I hope this will be useful to someone else with the same problem. Credit for the fix goes to Kenneth P. Turvey, who responded to a question on the Ubuntu-users mailing list.
The instructions:
Run alsamixer
Unmute all the outputs by hitting “m”
Hit tab to go the capture settings
Highlight the “Mic” setting using the arrow keys.
Hit space to enable the microphone.
Highlight the “Capture” setting using the arrow keys.
Hit space to enable capture (note that just because you have volume bar
here doesn’t mean it is enabled).
Hit escape.
This is great news! You raise an interesting point, and one that I resonate with.
Thanks for interesting and the helpful information I shall necessarily take advantage of your advice. For a long time could not find the similar information.
I can’t believe, I had the same problem! Everything is fixed now, with the help of this post. Thank you very much!
Thank you for the information. Two other things I did that helped: 1) Turn the mic volume up, and 2) find the “Mic Boost” option - if your sound card has this - and unmute it if it is off (press the ‘m’ key). This should help volume levels quite a bit.
Wow! I didn’t believe first this works but according to the comments it does. I’ll copy and store your advice for the furure
Thanks! I already thought the line-in wasn’t supported on my Fujitsu 7020!
Nice strategy. Unfortunately it does not work. When I press spacebar to activate mic recording, I see mic in red letters, and L and R (for left & right channel I believe). But when I try to press the up arrow to increase mic volume, nothing happens.
I still can’t record any sound!
Same problem as Anil. It was working the other day till I installed Skype and was trying to get that to work but never did. I am wondering what skype might have done to my system settings. Where would I look at what my mic is set to?
I believe the mic “volume” shown in alsamixer is the “loopback” output played back over the speakers. Don’t think it does anything for recording… HTH
I didn’t know that the capture setting also had to be enabled.. problem fixed, thanks!!
Thanks a lot!!! I had been struggling to get my mic work with Skype for almost one whole day without any luck. I followed your post and it got fix in a snap.
Cheers
You actually helped me a lot. Thanks!
Holy mother!!!
This is insane! I turned Alsamixer Capture off and back on, have not found the Mic Boost switch, but eventually the recording volume were amplified! Thanx man, this is insane and unbelievable!
great
Ca fait un bail que je me mordais les doigts dessus…
With the GUI mixers, I could find no visual confirmation and/or control like the red “Capture” activated by pressing the space bar when using AlsaMixer. Pressing “space” using the Gui version (AlsaMixerGui) toggles the capture feature, but with no indication whether it is on or off! Ten seconds after following your advice, I heard my own voice under Linux for the first time! Now I can try Skype! Thank You! Thank You! THANK YOU!
Dude, this is so cool. Finally able to use skype, and you saved me from buying a new microphone in desperation.
i use gnome alsa mixer and the microphone works ok on skype
this is great. i can hear the input from my mic into the computer speakers now. However, sound recorder still doesnt work. Neither can I make any outgoing calls with Skype. (Ubuntu Feisty 7.0.4). Would appreciate any help.
Same as Yogesh, I can hear my mic through the speakers, but Sound Recorder isn’t working, and nor is Skype.
I have the same problem with ubuntu, some body find solution !!??
Thank you very much! My microphone didn’t work until today with your guide. Thanks again
Ubuntu Feisty 7.0.4 has different settings - can someone point the way to getting the microphone to work on Feisty. I can hear through headset but mike doesn’t work. I have a Logitech ClearChat Stereo headphone/microphone set. With a daughter in Nicaragua, Skype is an essential! Any solutions out there???
thanks for your help en howto ! it helped me with feisty fawn.
Hi probably I’m stupid but I do something wrong when I apply the instructions.
when I hit tab to go the capture settings I don’t see the “Mic”.. can someone tell me what I do wrong?
ventrilo works with wine now \o/
my microphone is not working.i can hear the sound .
Same as Yogesh, Nick and Zak
Using alsamixer -c1 might do it for some…
See: https://www.sk3ptik.net/blog/?p=47
Thanks !!! now I can use Skype, only when i reset my laptop, i made this instructions again
It works in ubuntu 7.0.4 (feisty fawn) !!!

Guys - unmute Mic with “m” and Capturing status is shown by the two circles : white - no capturing; red - capturing. Click the MIC text below the controls in Alsamixer , then space and WORKS!
This is for for google searchers:

Microphone not working in ubuntu 7.0.4 (feisty fawn)
Thanks! This helped me, but I really solved the problem by turning the booster on. After that, I had to get rid of the hissing sound by lowering the mic volume. I was using Ubuntu Feisty Fawn.
I finally managed to get my front microphone jack working! For my computer, the setting for had to be switched to “Independent”.
Also, at first, I didn’t realize that there are more options in alsamixer than are presented on the screens. If you keep pressing the right arrow, you’ll see more columns within the view you’re in (Playback/Capture/All). I had to scroll this way to find the mic boost setting. As it turns out, while I needed the mic boost for my old computer microphone, I didn’t need it for the headset microphone.
You rock! it worked for me too. Thanks, this was for Gusty, on Dell Inspiron. if that is to add any knowledge to it.
I just can’t get it to work on my compaq c500. Is there anything obvious that you don’t even mention???
[...] tried this brief Ubuntu microphone little guide based on text-mode alsamixer, tried it and [...]
Ty! Ubuntu 7.10 on HP Compaq6715b.
Thanks much — fixed my problem– working well now.
Ubuntu 7.10 on Vaio PCV-R556DS.
you are great, I couldn’t do by myself. Thanks a lot,
works also for ubuntu 7.10 on IBM Thinkpad R60e
You are a legend - this has allowed me to use my language software in Windows via VMWare, it works perfectly.
Thank you!!!
(Incredible that 2 years on it’s still necessary to do this!)
where to initiate the alsamixer?
It didnt work for me as my mic was already set and also capture..but i get this error in the preferences->sound menu
gconfaudiosrc ! audioconvert ! audioresample ! gconfaudiosink profile=chat: Could not open resource for writing.
i use gutsy
to Carthik: thanks for the recipe! There is one little problem with that “unmute all the outputs” since I have got there an option “Mic as Output”, which enables sound output through the mic socket and no signal gets in, as a consequence. So this one should stay muted.
Mine works too. You guys are great.
Thank you!
What is alsamixer??
Fantastico entre los pinos!!! It worked on my HP DV8000!! Cheers, mae! Pura Vida!
Outstanding! Now I’ve got Bluetooth,Sound,WIFI,Webcam working on my Sony SZ laptop using Ubuntu 7.10!
It’s possible just be persistant my friends!
Laura: alsamixer is a program that you run from a command prompt. It is like volume control in windows.
thanks a lot man. All i had to do was turn up the volumes and change the output. Thanks a lot
I just found out that i hadvolume cntrol with the wrong device 
Cheers for this: pure smoothness!
Thanks, that fixed it for me too.
Big thanks! Solved my problems too! Linux Mint 4.0 Daryna Fluxbox CE on Lenovo A55 desktop, HDA-Intel AD1986A sound card
french tranlation :
Le microphone sur mon portable ne fonctionnais pas bien et j’ai trouvé un petit guide pour le fixer. J’espère que ce poste sera utile à d’autres qui aurais le même problème. La solution est l’oeuvre de Kenneth P. Turvey, qui ont répondus à une question sur la mailing list des utilisateurs d’Ubuntu.
Instructions :
Lancer alsamixer dans un terminal.
déconnecter toutes les entrées et les sorties en frappant “m” et avec les touches de direction gauche/droite.
Tapez Tab pour aller dans les paramètres de capture.
Régler le “Mic” avec les touches de direction.
Tapez Espace pour activer le microphone.
Ajustez les paramètres “de Capture” avec les touches de direction.
Tapez Espace pour activer la capture (remarquez que la présence d’une barre de réglage du volume ne le signifie pas que la capture est activée).
Tapez Echap.mm
French translation and corrections :
La procédure fonctionne mais la traduction induit des erreurs :
Erreur : déconnecter toutes les entrées
“un mute” veut dire “non rendre muet” c’est à dire réactiver les sorties
- Pour les sélectionner, appuyer sur les flèches droites et gauches
- Appuyer sur la touche “m” de manière à ce que les colonnes soient en vert.
Erreur taper Tab
Appuyer sur la touch tabulation, celle avec le signe Tab, ->| ou |<-
De même il faut :
Appuyer sur la touche espace
Appuyer sur la touche Echap, “esc”
Thanks!
Works for Asus F3Sc & Dell Latitude D630.
Thanks very much - I was really stumped trying to get the microphone to work on my HP nx9420 laptop, in a new install of ArchLinux. The secret was setting capture to capture, with the space bar.
Great tip, any thanks
Nigel
Thanks.
Ubuntu 7.04
Thank you, for the help.
I could solve my problem, which was disturbing me for the past couple of days
Thanks for this great post. I finally got skype working on Ubuntu after following your post.
HELP!!! I cant get it to work out!… I run alsamixer, and when Im supposed to press spacebar on the mic to enable it, nothing happens!.. maybe I just donw own the latest version of alsamixer!… if you can help me please write me to cespinal17@gmail.com…
thank you!
Hi everyone,
thanks for all the support, but my problem isn’t quite solved. I can record, but have a big buzz. I’ve played with all the settings, but the best result I get is to influence both the buzz and my voice equally. I’ve tried unplugging my WLAN router but that doesn’t help.
Something that might be a hint: in alsamixer, to the right of the two capture settings there is a channel called digital. This also influences the loudness of the recording (including the buzz).
I hope someone can help,
Mirco.
