Hello everyone,
I've got it sorted now. I rechecked the Vaio sony site and I found the driver I needed.
Advice to anybody that may read this. Double check what your original driver was before downloadling any drivers, I messed up big time by asuming it was REALTeK, I was wrong. I recommend using computer manufacturer as first port of call, then try the motherboard makers site. DON'T USE THE FREE SCAN SCAMMERS, I tried one, it didn't detect I had no audio driver!!!! Say no more.
Thanks for reading.
