Public bug reported:

On upgrade to 17.04, my webcam stopped properly working, in the sense
that when video chatting with others, they hear a chipmunk-like noise. I
used the word chipmunk because I saw this:

https://bugs.launchpad.net/ubuntu/+source/linux/+bug/858412

This issue happens with every video chat application I've tried: hangout
(chrome), viber, also cheese. I went through some Ubuntu wiki page about
fixing sound issues which made "cheese" record once ok after some force-
reset of audio, but not the second time (some crashes seemed to happen
as well, where the audio was completely disabled globally until
restart).

I know the above is not very precise, so here's what I can tell for
sure: When video chatting, the audio from my logitech webcam (C210)
sounds like a chipmunk after I upgraded to Ubuntu 17.04. This is with
the 4.10 kernel. If I boot the same Ubuntu with kernel 4.8 (leftover
from Ubuntu 16.10), it works correctly!

The above experiments suggest that there is nothing wrong with my config
files or package installation. But that it's a regression in the
kernel/drivers.
