Public bug reported:
Fresh install of Ubuntu 16.04 LTS on a Lenovo Thinkpad T-410,
sound drivers and codecs appear to be correct, but cannot get any sound from
either the internal speakers or the external headphone jack.
I tried many debugging procedures and nothing seems to help.
Furthermore, the sound-settings panel does not show a hardware tab and the
output tab shows only "Headphones-Built In Audio".
