I have just bought a Freecom Internal CD-RW. The manual says to connect the audio cable to the sound card. I haven't looked yet, but I anticipate that the DVD audio connector will be connected to the sound card. Do I disconnect the DVD sound cable? and put the CD-RW in its place. I have never opened a PC before so forgive any obvious ignorance please. The manual also says to make sure the connections are oriented so that L corresponds to L and R to R but I can't see any little L's or R's on the jacks on the ends of the audio cable that has come with the CD-RW and it isn't clear which end goes into the CD-RW and which end goes into the sound card!
