I just wondering are you running crunchbang in a virtual environment. When you run an OS in a virtual machine you don't have access to your real hardware. It's uses it own virtual hardware ie hard drive, soundcard,network card and etc...
Pulseaudio will see only your virtual soundcard only and not your real soundcard.
If you're not using a VM, then I'm sorry the steps didn't work for you and your soundcard.
