Upgrading Ubuntu Gutsy to Hardy

I did my duty and upgraded from Gutsy to Hardy, after letting Hardy settle for a while. For the most part it was painless (unlike the last upgrade to Gutsy!).
Unfortunately the sound was now broken I have a HDA-Intel AD198x Analog chip set.
Then I discovered (just when I needed it of course) that my Samsung ML-2010 USB printer didn't print anymore.
I would get this weird error...
Unable to open device hal:///org/freedesktop/Hal/devices/...
After Googling I found this, he was half right, I don't know why but it works, except that I needed to do...
sudo chmod 700 /usr/lib/cups/backend/usb sudo chmod 700 /usr/lib/cups/backend/hal sudo killall -HUP cupsd sudo /etc/init.d/cupsys restart
ie both usb and hal.
That fixed it... Amazing!
Now why won't my audio work???
Ok now it does work, go figure. The only things I changed were added this to /etc/modprobe.d/alsa-base
options snd-hda-intel model=3stack-dig
and made sure that Front was checked in the mixer and turned up.
Not sure which of those fixed it though.
