microphone disappears upon installing Lucid
I just did a clean install of Lucid. So far everything seems to be working except for the built-in microphone. I remember that in Karmic or Intrepid I had to fiddle some settings to get it working, but the audio configuration appears different now. I've tried everything in System > Preferences > Sound > Input to no avail. I tried searching this forum as well as knowledge76 for similar posts as well - if I missed it, please point me in the right direction.
Thanks in advance for the help.
