What kind of output does the PowerMac G4 Digital Audio have out of its pro speaker output jack? If I connected a 2.5mm -> RCA adapter(s) to it, would a receiver be able to use its digital output (i.e. is it standard spdif?). Basically, I'd like to hear my DTS music albums in my den instead of static in Airtunes mode (my other rooms with AppleTV, Airport Express, etc. are connected to DTS comaptible equipment). Perian can convert DTS to stereo, but only if it's sent the signal and knows it's DTS. The fact the DTS music CDs are "pretending" to be Redbook PCM audio means all I'll ever get is static (short of someone providing some software solution). But digital output to a receiver would decode it like all the other rooms. But will it work?
