Microfone sound is too low

Asked by Wladston Viana

When I try to use the microphone to make recordings, the recorded sound is too "low". The recording barely captures the sound .... I shout for the recording, and when playing back I can barely listen to a whisper.

I have no problems wirh audio playback.

I'm running Ubuntu feisty 7.10, with a Toshiba R20 tablet pc.

I know it's not a hardware issue, because it works perfectly on windows vista (I have a dual boot config)

thanks for the help!

you may try to switch on the "mic boost option" of alsa.

try to find this option in the gnome-volume panel.

runnig KDE, I don't know if you will find it. you can also do it in console with the command "alsamixer", going on the mic boost switch and pushing the "M" key to unmute it.

hope it helps

Oliver,

I tried hard, but I couldn't find this option ... can you post a screenshot ?

the only thing similar that I found was "in-gain", but it's already at the max.

you can find a screenshot at http://<email address hidden>/alsamixer.png

but you may not have this option. this could depend on your sound card model. what is your sound card model ?

you can know that by typing " lspci " in a console and identifying the right section

this is my sound card :

00:1b.0 Audio device: Intel Corporation 82801G (ICH7 Family) High Definition Audio Controller (rev 02)

I have the micrphone gain option on windows, but works ( on windows) even without any gain...

I couldn't view the image : "Le site web de free a récemment changé :)"

you may try this

to switch to the capture panel in alsamixer, use the tab key.

really strange you don't have that "mic boost" thing ...

if that does not work for you, I don't really know what to do. Maybe using alsaconf to reconfigure your sound-system ?

oh, that did work!

can you help me find help that option on the normal gui ?

unfortunately no... I don't have GNOME installed. I guess that you should play with the switch in gnome-volume manager with the alsamixer capture window open until you see you find the right button.

good luck :-) !
