Integrated microphone isn't detected at all and that was working under Mint 9 Isadora x64 bit, also external speakers don't work if I connect them via an AUX cable.
Also Headphones don't work when connected.
Works fantastic after inserting this fix:
gksudo gedit /etc/modprobe.d/alsa-base.conf
and add the following to the end of the text in the file
options snd-hda-intel model=thinkpad
