Does anybody know if there's a hack to get the Mach460 to accept an auxilary analog input? I'd like to add an aux input plug (either RCA or female mini jack) that I could connect any sound device to... Is there a hack that I could use (splicing wires, etc.) to add such a plug? I'd love to connect a used Toshiba Libretto filled with a couple of gigs of MP3s... Thanks.
