Sure enough the culprit was youtube/flash all along! When I closed all the browser tabs with flash in them, my computer went to sleep as expected. So I updated to the latest version of flash, updated my audio drivers, but I still cant get my computer to sleep when flash is running! Gahhh so I have to remember to close my web browser before I step away form my computer now
Anyway, anyone else having this problem? Heard of any workarounds?
