I downloaded power amp and the upgrade from the market. I need to be able to play .wav files that I recieve in my email. Our voicemails are forwarded to our email, which i have on my MotoDroid (OG!). Anyway, when I open the email, and try to fetch the attachment, it doesn't default to the power amp player. It doesn't even give me the option to. Any help on getting this to work?
