Do I have to hook up an audio cable when I install a cd burner and how do I do It if needed?

Answer 1

If you want to play sound from it ... YES.
To copy or create CDs with sound ....NO.

"If your CD drive came with an audio cable and your sound adapter has a free connector ( on the sound card or on the motherboard if your adapter is integrated ) for its end of the cable, attach one end of the audio cable to the connector and the other to the CD drive."

"If the sound adapter has no free connector, then choose which device you want to use as audio player and attach the cable."
