I confirm this occuring on the final Jaunty. Made several test trying to figure it out. On releases prior to Jaunty it's enough to add this
"alias snd-card-0 snd-hda-intel options snd-card-0 index=0 options snd-hda-intel model=vaio" But, after upgrading the sound is still messy. To solve you need to add (just in one line) the following options snd-hda-intel model=vaio enable=1 index=0 position_fix=1 probe_mask=1 That should make switching back to normal.
