Hello, I have a Dell Inspiron N4050 running xubuntu. The system doesn't recognize my internal microphone (only Monitor appears on audio mixer) unless I plug and then unplug an external microphone. Then, the laptop's internal microphone appears on mixer and I can select it, and it works fine. But if I don't plug an external one, there's no way to make the laptop's microphone visible to the system, wheter I want to use it on audacity or firefox, nothing can find it.
I don't have the same problem in other distros (including standard ubuntu), so I believe it's not a hardware issue.
I'm gonna post here some outputs that I think could help you guys understand what's going on here, because I couldn't figure it out...

Thank you all for your help!
PS: Sorry for the portuguese: "placa" means something like "board", "card" or "chipset"; and "Dispositivo secundário" means "secundary device"
