Upgrade of my ThinkPad T510 with F14 to F16 - sound problems

A week ago I have decided to move another two steps on my Fedora ladder.
I was very surprised and please with how upgrade went and no major problems occurred.

But later in a week I found my microphone (mic) is not working and Twinkle is not playing/capturing sound as well.

After some googling around a bit I discovered that I need to modify my
/etc/modprobe.d/dist-alsa.conf file putting new following line at the beginning of commands:
options snd-hda-intel index=0 model=thinkpad

Restart the system and problem is still there.

Then I realize that my user is not able to access /dev/snd device files, but there is a group called "audio" preconfigured for this. Obvious solution was to add the user to the group.
sudo useradd -G audio <your_user>

Last step is reboot, test and enjoy your sound!
