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!
