The cheap SoundBlaster that everyone in the world stocks seems to be the SB0410, but the SB0100 is the one that has an RCA jack on it for coaxial S/PDIF. I ordered one of those online, and of course the fuckers shipped me the SB0410 instead, which has only 1/8" phono jacks.
But, the blue plug is labelled "[line-in-icon] [mic-icon] or digital_io". Does that mean that it will work as S/PDIF output if I stuff an 1/8" mono-to-RCA adapter in there? I can't RTFM because the only manual is on a CD in "Windows Help format" (on which "strings" does not work.)
