Thanks Marcelo, When looking at the output from 13.04, you seem to have forgotten to turn up the microphone gain. Also you seem not to have done any recording test before running alsa-info on 13.04.
('Capture' and 'Internal Mic' gain are both at minimum values.) Anyway, assuming you've tried that and it still doesn't work, there were no other differences that looked relevant to me. I also browsed through the changes to the most relevant file but didn't find anything. So, next step is to check latest upstream drivers: https://wiki.ubuntu.com/Audio/UpgradingAlsa/DKMS And if it still does not work, a git bisect... -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to pulseaudio in Ubuntu. https://bugs.launchpad.net/bugs/1127699 Title: Internal microphone does not working in Dell 3420 with Ubuntu Raring Status in “pulseaudio” package in Ubuntu: Incomplete Bug description: Internal Microphone in Dell Inspiron 3420 a.k.a Dell Inspiron n4050 is not working with Ubuntu 13.04 - Raring Ringtail, no matter what I do.
