Okay, so basically what we have here is that the sound is very, very low 
unless you put it to the top level and still the image capturing has some 
hicups... let me Google a bit.

I found this bug report for Ubuntu:

Logitech camera microphone does not work / makes "chipmunk" sound 

At comment #37 there seems to be a pacth for some cameras and C910 is 
listed there. Also note that as per the other user's comments, the camera 
looks like it worked fine in kernel 2.6.38, not sure if it's an option 
(or even worth for it) for you to test with that kernel or with a newer 
one :-?
