Hello All, I bought a new desktop early part of last year which came with W10 installed. It only has three sound connections, these being pink for mic, green for speakers and a blue one. I have a Cambridge DTT 2020 sound system with 5.1 speaker units. There are three sound input leads on the sub woofer unit, one for Speakers front, one for speakers rear and one for the sub woofer. The computer came with a Realtek audio driver which would have allowed me to reconfigure the rear mic socket and the rear blue sockets for the rear speakers and the sub woofer unit. I think it was the install of the W10 anniversary update that caused the driver to be replaced with the Microsoft HD audio driver and this will not allow me to reconfigure the two audio connections. Is it possible to replace the MS HD audio driver with the Realtek audio driver on the MSI disc that came with the computer. Thanks.
