a similar post was posted recently but i didnt understand it well.
as im building my pc now, and i got a dvd rw drive and also a dvd rom drive, i connected them to the ide cables etc. but my motherboard has onboard sound. so do i really need to connect the audio cable from the drives to the sound in my motherboard and where would the pins go as it is onboard?If i do would i have to connect both and are there enough pins for both?
Yes you do need to connect these cables. I do noy know what your mobo is but on mine they are listed as internal audio connections CD1 & AUX1. In your motherboard manual look for these two connections.
