Do pay per sound still work? Alternatives..

I'm buying some cheap traffic that are real human visitors except I don't know where to send them to make money, so I thought about one alternative with is pay per sound.

Anyone ever use these? I haven't found a forum post after May 2008 talking about netaudioads or sellingppp, so I wasn't sure if that was because they don't work anymore or what?

Please recommend a pay per sound that you've used and got results with, or recommend alternative to send traffic to. (No cpa offers to send this traffic to because it's not of high quality)

Also, another alternative I was thinking was sending this cheap traffic to associatedcontent and getting paid for the cpm? Anyone do that?

Please tell me how I can make more money with this traffic.
