It looks like this webcam has not been working properly since Ubuntu Hardy. https://bugs.launchpad.net/ubuntu/+source/linux/+bug/280657 I'm not sure of the version included in Hardy. Would it help if I tried to find the GSPCA version from Hardy to compare the changes? In searching for details on this webcam model, I came across some patches that you submitted a while back that initialize the GPIO with different values. I tested those, but saw no results. I see you've worked on this specific driver quiet a bit in the past: http://linuxtv.org/hg/~hgoede/gspca/rev/65247a979498 Is the previous maintainer, Michel Xhaard, still working on this driver at all? I wonder if he might be able to help identify the problem or narrow it down. Which function is called when I open Cheese or other video applications? Initializing the webcam appears to be correct, however, sd_start() or the one that starts the video capture appears to be toggling or changing some setting. If I knew of a way, I would insert more debug messages to help pinpoint the place where the microphone breaks along with some boolean to show that its working or not.
