Bug Description
Recent Sony Vaios use snd_hda_intel for audio, 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
Then restart ALSA:
]$ sudo /etc/init.
(In Jaunty, alsa-base has been renamed to alsa-base.conf and you have to restart your machine to effect any change; also see https:/
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.
Andy Whitcroft reckons this can be handled by the kernel's quirk subsystem if appropriate info is provided:

So can people please add comments with their model number, the working "model=<something>" string from /etc/modprobe.
]$ sudo lspci -vvnn > lspci.txt

I might add that this was last tested on Hardy alpha 5.
