While attempting to configure my Macbook Pro's built-in webcam microphone for Mumble, I noticed that the microphone was not detected.
Opening VLC, I attempted to capture the built-in webcam in an attempt to see if it would detect the microphone, which it did not. (The webcam worked out of the box flawlessly.)
A previous AskUbuntu question covered this issue, suggesting that the line
options snd-hda-intel model=mbp101
to be added to
After restarting, this had no noticeable effect. Attempting
mbp102 yielded no effect as well.
