No Sound After installing in Bartop...

[pyra1212]

I got a Dell Optiplex 620 that i took apart and installed in a bartop cab that i built.  the sound was working fine before but now i get no sound.  I tried reinstalling the audio driver and even reinstalling XP. but still no sound.  I'm pretty sure I reconnected all the wires  but Im not using dvd rom and floppy.and didn't connect them to the motherboard.  any ideas what the problem is?

Check sound settings in control panel, mine gets muted sometimes for no reason.
Must be some kind of cruel joke played by Bill Gates.

Failing that install a pci soundcard.   I have had a dell GX520 (Although it may actually have been the 620) do exactly the same thing,  If I connected it up to my amp and ramped the speakers all the way up you could still hear sound coming out, but it was just so low as to me unusable.  I never did figure out what happened. Threw in a £4 soundcard and all was back to working happily.

I bet I know what the problem is. Did you remove the front-panel audio? Usually has a headphone jack and a mic input. When I build Lime Aid, The Lime Arcade I found that on some mobos when you remove the front panel audio you end up with nothing because the signal goes from the mobo to the jack up front [so that if you plug into the front it mutes the rear] and then back to the mobo to the sound output on the rear. I hope that made sense. What I ended up doing was just putting some of those master/slave jumpers on the audio pins and it was fine.
