I was trying to tune my guitar, when I've decided to increase the microphone input volume. Well, i went in the sound settings and it worked.

Also, in the connector options list, there was selected analog microphone/microphone 1. Well, I don't know what happened with me, but I've changed that to another option (analog line-in), and seeing it doesn't work (obviously, the laptop microphone was the only one "plugged-in"), I tried to change it back.

But when I've done that, the connector option hopped automatically to something that isn't microphone, line-in, input or analog video, but no microphone, making it undetectable anymore.

Example: I choose Analog Video. I change input volume, it stays. I choose Microphone. When I change input volume, it hops to Analog Video.

Can this error be fixed somehow?

Could you please include the output of pactl list | awk 'BEGIN{RS="\n\n"}/^Source/{print}'? –  bseibold Oct 21 '11 at 15:09
    
shame on me, but how could I do that? –  iulian Oct 24 '11 at 19:52
    
Open a Terminal (it's usually in "Accessories") and enter that line there. It will spit out several lines of information which you can select with the mouse (scroll up if necessary) and copy. –  bseibold Oct 25 '11 at 8:34
    
I thought it was more complicated than that... –  iulian Oct 25 '11 at 12:09
    
Well, unfortunately(?) that looks ok, nothing out of the ordinary there. –  bseibold Oct 25 '11 at 16:03

ulian, I had the same problem you experienced.

I solved it by doing these steps:

  1. sudo apt-get purge pulseaudio
  2. sudo apt-get purge pavucontrol
  3. rm -rf ~/.pulse/

And then rebooted, reinstalled pulseaudio:

sudo apt-get install pulseaudio

then rebooted again.

Hope this helps.

Vince

Try Alt+F2 and pulseaudio -k. Then open the windows again, see if it'll be happier now.

still same thing, not happier... –  iulian Oct 24 '11 at 19:53
    
Alright. Try installing 'pavucontrol', it is PA's own tool for configuring things - does that work? –  Vadi Oct 24 '11 at 21:45
    
it seems pavucontrol doesn't work either :( –  iulian Oct 27 '11 at 14:47
    
Thanks Vadi, this worked for me with probably a slightly different problem. I was plugging in my microphone and it wouldn't recognize it. If I rebooted, it would be recognized, but that seemed like a very annoying thing to do each time. –  Milimetric Aug 11 at 16:06

often you have to use the alsamixer to select which microphone/input to use. The same thing happened to me with my desktop, which has two microphone jacks.

Start alsamixer, press F4 to look at Capture, then F6 to select the sound card to use. In some cases the microphone is a different sound card. Then use the controls to activate the microphone and adjust the gain, and possibly the boost if you want that.

I would say you should uninstall and re-install Banshee, open Terminal(Gnome Terminal) and type sudo apt-get update before trying it again.
