Dual monitors and audio are pretty much the two places Linux trips up compared with Windows now. NVidia provide software for using dual monitors with their cars which I've heard lots of good about, but I'm under the impression it's still quite clunky and occasionally forgets itself.

Do you have onboard sound in the laptop? Does that work? If so, it might just be a misconfigured default. As root, run
Which will list the available soundcards. Running
Code:
asoundconf set-default-card <cardname>
Where you replace <cardname> with exactly the name that came up in the `asoundconf list` command should change the default.
