Internal Microphone not shown or listed - Ubuntu 11.10
I am running Ubuntu 11.10, 32-bit, installed with Wubi, dual-booting with Windows 7 on a Sony Vaio, Intel B940 processor.
My internal mic doesn't exist, according to PulseAudio settings and system sound settings. There is no mic listed under the Input tab. I have Alsa installed as well. There is a mic input listed under the HDMI tab, but the only other tab is the USB tab. No mic there either. The mic is fully functional when booted to Win7, and did work at one time with the same installation of Ubuntu 11.10.
My main concern is using Skype, and that's the main thing keeping me from going to a full install of Ocelot. I am a newbie with Ubuntu, but have had some experience years back with Mandrake 9.
Thanks for any help,
-Dale

When I run alsamixer, I still see no active mic.
"Mic B" has red "L R" and "capture" under that, but no level bar comes up.
"Mic C" "Mic E" and "Mic F" are dashed out.
"S/PDIF" is red, green block has "00".
"Capture" is white and shows a red "L R" with red "capture" under it and a 100% bar/numeric level.
"Analog mic Boost" on the far right shows 40dB.
"Master", "PCM", and "Beep" appear to be normally indicating bars - at 100, 100 and 60%, respectively.

If you go to 'sound' in dash, is the right input device selected?

I came across the solution to my problem in a Skype community: http://
Turn PulseAudio autospawn off, normally: $ echo "autospawn = no" > ~/.pulse/
Kill PulseAudio: $ killall pulseaudio
Shut down and restart Skype
This allowed me to see/adjust the mic and all other inputs/outputs with the Alsa Mixer. My proper hardware is also indicated. Of note, there was no hardware indicated in Settings > Sound, presumably because PulseAudio was killed.
Thanks for trying to get me running. It is appreciated.
