  Logitech (Camera)
  Mint (older version)
  Works partially
What works:

Video in Cheese, sound in guvcview

What doesn't work:

Sound in Cheese, video capture in guvcview by default codec MPEG4-ASP

What was done to make it work:

This webcam works perfectly only on guvcview but with some changes in the application settings.
Trying to record video with Cheese results in video capture only and there is no sound, even after activating every mic option in alsamixer or selecting Microphone Webcam C270 in the Input Sound Settings.
When operated in guvcview, there is clear audio if you select "USB device" in the audio controls of guvcview, but no video because it's set by default to MPEG4-ASP in the Video-->Video Codec settings.
Change it to MPEG4-AVC (H264) and it works fine.
