Only one sound socket on M/B

  iqs 20:31 10 Nov 2007

I have just installed a DVD ROM drive in my friends PC.Originally he had just a DVD RW.

Both drives work fine.The only problem is,I can not locate a spare socket on the motherboard for the audio connection for the DVD ROM.

There is one motherboard CD IN connection which is being used by the DVDRW,the AUDIO 101 socket is connected to the front PC speaker inputs.

There is one free socket called the AUX IN,can this be used for sound?.

According to BELARC the motherboard is a SIS-667.The PC is a E-SYSTEM ES-102 with WINXP.

Any help appreciated,thanks

you don't need one. Let windows control the sound via the IDE cable.

Go to device manager> right click the dvd drive in dvd/cdrom drives and pick properties. in the new window pick properties again and place a tick in 8 enable digital cd audio for this device.

Agree with AI33 just forget about it. I just use digital audio. Try it it works without the cable.

AI33 and Totally-braindead.

I now have sound..

Because the DVDRW was connected I thought the same for the DVD ROM.You certainly learn a lot from the forum users.

Is there a difference between using the audio connection and the IDE connection?

Many thanks to you both for your help.

The audio connection I believe is only for analogue sound.
To be perfectly honest I don't know what difference it makes but since my sound works perfectly without it and digitally I haven't bothered to connect it.

I'm sure someone will explain the advantage of having it connected - if there is one. I think its probably just an older version of connecting it and has no real advantage. I could be wrong though I'm sure someone will explain its use.
