For me, its not the MS UUA Driver thats the problem. I also have to use this driver with the P5GD1 Motherboard, and so its nothing new for me.
What is the issue, is simply that the onboard sound, while fairly good quality, is also struggling when I am doing any disk accessing. This could be the disk controlers problem as I have found that the whoel system is a pile of rubbish and poor slow, but everythign I have gone through checks out as fine, from the drivers to the DMA & other BIOS settings, its just a fowl PC overall.
But then, even other soundcards that I have, simply dont play nicely either, so WTF is going on?
To be honest, I dont rate this motherboard at all. The other Intel boards that I have also have this issue to be honest though... They are fowl compared to AMD Boards I have.
