Basically the PS3 drivers are a bit of a mess and very few ppl use them so there is no step by step guide. On the top of my head there are two threads here that have collected quite a few problems and possible solutions, finding those would be your best bet.

Hello, I use PS3 Eye, with Arecord. You must use “test” button and look in the select field, the which one is ended by “working !”

For me, it work fine. with no more configuration. You may set yourself the input volume with this command in shell : “alsamixer” and type F4 and set the volume.
