Use (i.e. google to learn about) powertop.
This should help identify the bottlenecks.
While I hate to admit it, pulseaudio could be waking up your system a
bit more often than just plain alsa. This will change however with the
next release of pulseaudio which will use dynamic buffer sizing and some
advanced cleverness to actually cause far fewer wakeups... less than
pure alsa surprisingly (if I've understood it correctly!)
So you can always try some metrics by disabling PA and see if that helps
battery life. Also you can disable bluetooth and other wireless if you
don't use them as they are real hogs.
