Ubuntu - no audio after upgrade to 13.10

Question

I upgraded Ubuntu to 13.10 yesterday and guess what? No more audio! Hooray!

So I visited all possible posts (there are many) on the subject but none of the suggested alternatives worked for me. The most common suggestion I see is uninstalling and then reinstalling alsa and pulse:

$ sudo apt-get remove --purge alsa-base pulseaudio indicator-sound
$ sudo apt-get install alsa-base pulseaudio indicator-sound
$ sudo alsa force-reload

Didn't do it. Another suggestion was deleting the folder /run/user/{my_user_id}/pulse, but that didn't have any effect either.

The result of sudo aplay -l is the same as that of aplay -l (without sudo):

**** List of PLAYBACK Hardware Devices ****
card 0: PCH [HDA Intel PCH], device 0: ALC662 rev3 Analog [ALC662 rev3 Analog]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 0: PCH [HDA Intel PCH], device 3: HDMI 0 [HDMI 0]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

Thanks!

You can most likely use hda-jack-retask to fix it (http://lists.freedesktop.org/archives/pulseaudio-discuss/2011-December/012342.html). Go through each pin (including un-assigned ones), try setting them as speakers, playing a music file from beginning, and rinse/repeat until you find the working pin.
