Mic problem, Ubuntu 12.04 LTS

Asked by Dan

Hello.
I got HP pavilion dv5.
After having updated my Ubuntu 11.10 to Ubuntu 12.04 LTS, the mic doesn't work anymore (moreover, even if I record smth, the sound level of my speech doesn't move).

http://www.alsa-project.org/db/?f=420be9c39383d74ba5afdee323ca784d50fce645

How can I solve this problem?

Thank you.
