Problem with Mic in and Line out ports and Realtek AC'97 Audio

Hello all,

I am new to the Forum but after a week of searching for answers I figured mine must be a unique problem.

I've had a no sound problem with my PC at work for sometime, programs and browsers have always run perfectly, but with no sound.

I suspected a disabled sound card, but the PC has a sound card built in on the MB and it has always been enabled.

My second solution was out of date drivers, and after seeing a yellow explanation mark next to my sound device, I downloaded the appropriate driver, as well as the latest DirectX for my OS (WindowsXP).

I then proceded to download all available codecs for my built-in sound card, the Realtek AC'97 Audio model. (Complete specs will follow)

So far no good, but with these was installed the Multi-Channel Audio Configuration program by Realtek, which enabled me to see that upon inserting my speakers into the line-out, it was being detected as mic-in. Bizarre?

I tried fiddling about, trying line-out, in and mic ports on the front and rear of the pc, but in every case all that was recognized was a 'Powered Speaker in Mic-In connector'

Anyway I downloaded a few media players with visualisation, to make sure that the PC was indeed generating sound and it wasn't just failing to comprehend audio files completely, admittedly this should have been an earlier move. But everything was 'Ready' 'Ok' and installed, status wise.

So then I'm fiddling about again and I try running the Realtek Audio Configuration's connection check whilst playing some mp3 files in wmp (my speakers currently in line-in). And for 2 seconds whilst the test is commencing, I hear the first sound this computer has ever produced, but upon this tests completion, and the result that the powered speakers are apparently connected to 'Mic In', the sound fails once more.

This has got me, once again, royally stumped and I've filtered through many threads regarding the failure of the Realtek AC'97 codecs, drivers etc, but I've reinstalled all the necessary software countless times and feel this could possibly be a hardware malfunction? Nevertheless I decided to put it in the audio thread, sorry if I've done the wrong thing.

Thanks to any helpers in advance!
Please help!
