Noise when recording with internal microphone on SONY VAIO

[Victor Zverovich]

When using the internal microphone on my SONY VAIO laptop running Ubuntu Natty I get a loud noise. Adding "options snd-hda-intel position_fix=2" to the file /etc/modprobe.d/alsa-base.conf solves the problem. However it would be nice if the mic worked with the default settings.
