Start 'alsamixer', press 'F6' and see a list of your sound cards. I'm not sure about it, but maybe your webcam would be there, in which case you should just choose it and tune the volume for it. Good luck! Vladimir -

Some alsamixer tweaking was needed. Strangely, I needed to change "Channel mode" from "6 ch" to "2 ch" for my intel-hda soundcard. I still can't get the webcam mic to work :-( Thanks a lot!

I prefer to check this in 'alsamixer'. If you have several microphones on your PC, there should be a possibility to choose the device to record the sound from (on my system there are 'Line', 'Internal Mic' and 'Mic' options). If you choose a correct device, then check if it is not muted as well (a symbol 'M' in Alsamixer means 'muted'). If the device you need is un-muted, then raise the volume level (or maybe 'Mic Boost' as well). If none of the above helps, then perhaps your device wasn't properly set up. You need to specify you soundcard model by hand in some cases. For example, on my laptop I added the string options snd-hda-intel model="targa-8ch-dig" to the file '/etc/modprobe.d/alsa.conf' and rebooted, after which I got an access to all of the features of my soundcard. Hope this helps. Regards, Vladimir -

Alsa always sets the mic controls I need back to 0 and won't ever save what I was using. Each time I need the mic I have to enable 3 settings in KDE mixer. (which also exist in Alsamixer if you prefer to use that tool - hit F4 once in it) --- Front Mic - turn it on. My system has 4 settings. I raise it by one click at least. Note that in KDE I must grab the one on the right. The one on the left won't raise the pair. Alsamixer only shows one control. --- Capture - turn it up to 80% or so --- Digital - turn it up to 80% or so These settings work for me but Alsa won't save them on my system like it save headphone/PCM/Master settings so I have to turn them on by hand every time..

[gentoo-user] Can't get any microphone to work
Damn! I've been all morning struggling with this. I have an analog microphone wired to my hda intel onboard sound card. Also, I have a genius webcam (gspca_pac7302) with a builtin mic. I tried arecord but couldn't capture anything from any of it, so I guess I'm doing something wrong. But what? Below is arecord list output. Is arecord appropriate for this test or there is another tool I can grab? Thanks!
