I have a Dell Precision M6500 with Ubuntu 10.04 64-bit. Having the same problem (external plugged in mic works, internal mic doesn't), so cannot easily use Skype on the go, for example. How can I assist to help debugging this problem? I've installed linux-alsa-driver-modules-$(uname -r) from ppa:ubuntu-audio-dev, but as of yet, no joy.
