Simple problem, microphone does not work with skype on ubuntu. Know't solution.

A few details would be nice. Where are you plugging the mike in? Have you tried the sound recorder and the audio controls to see what the settings are?

My computer is a Vostro 1500, I am connecting the microphone in the only plug it brings.

When I try the sound recorder, shows the reception level indicator, however, when playing not heard anything and the volume is full.

The only solution to make microphone work is to install linux-backports-modules-alsa-generic...

Just go to:

Menu / System / Administration / Synaptic Package Manager

And search and mark for installation:

linux-backports-modules-alsa-generic

tip: if you have multiple versions click on the first and read the description which should inform what name to install...

If after the reboot and mic mute is off, still does not work, just go to terminal and type:

sudo nano /etc/modprobe.d/alsa-base.conf

and add or change the following:

options snd-hda-intel model=auto enable=yes

Then Ctrl+X, type Y to write and exit, reboot and mic will work.

Bye and have lots of fun with Ubuntu (the best).
