Microphone doesn't work (so can't use Voip)


Hello everybody, over the last few days I have desperately tried to use voip programs like skype and others but I cannot since my microphone isn't working. I have tried adjusting volumes with alsamixer but nope. This is my amixer output

I know the hardware isn't broken for sure. I have a Ubuntu Hoary 5.04. What can I do? I don't know if there is any connection but dual audio doesn't work either in my system. What can I do? Thanks in advance.

perhaps check to see if you mic boost is on?

and Capture 7 ? on your mic setting... check to see ifyou have the correct mic being captured?

simple stuff first.

1. is microphone plugged in to 'mic' or 'line-in'?
2. does alsamixer show 'mic1' or 'mic2' as its default mic channel...LOOK CLOSELY


I note that you have 'mic as centre' enabled..is the mic plugged in there? what happens if you turn that setting off?

I had to mute one of my microphone channels before the mic would work. Presumably some sort of clash occurs otherwise. Make sure only one of your microphone channels is active at any one time.

I can't face analysing those great long lists to make sure you already have
