(Get the code!)
The Sony Vaio SZ6 series use snd_hda_intel, which is generally good and supported by alsa >= 1.0.15, but the Ubuntu installer does not properly detect hardware and configure the driver. The well-known fix to this bug is to install the newest available alsa and add to the end of /etc/modprobe.
alias snd-card-0 snd-hda-intel
options snd-card-0 index=0
options snd-hda-intel model=vaio
This enables the headphone jack, speaker muting on headphone insertion, the internal microphone (and I think the mic jack, though I haven't tested it), which otherwise don't work. A bit of a pain when your Mum is nagging you to Skype her.
The Ubuntu alsa-utils package specifically excludes alsaconf (which autodetects and configures properly sound on my Vaio), so the other solution is to go to the alsa website, download and install from source then run alsaconf.
I'm pretty sure this affects a broad range of newer Vaios.
Clearly, sound should work properly out of the box - which it almost does.
