Hi guys, I have acquired a powerbook 5,8 I read this is the last in the powerbook line. Anyway I got a generic dvi to hdmi adapter and hooked it up to my Samsung LNT4067F LCD tv. I read that this model should support audio out of the dvi slot. The picture works but I'm not getting any sound. I'd rather not purchase a rca cable to go from the headphone jack to my tv if possible. Any solutions? Thanks in advance.
