[AO722, Conexant CX20588, Mic, Internal] No sound at all

[Sushenjit Bandyopadhyay]

Internal Mic was working in 12.04. t stopped working after upgrade to 12.10. I have tried setting mic and mic-boost levels in alsamixer as well as at the Input tab of Sound settings accessed via the sound applet at the top panel. These did not work. The recording levels at the Input tab of the sound settings do not register any sound,. Sound recorder as well as Skype does not record / capture any sound.

Thanks
