Hi all, many times reader first time poster,
been having lots of problems with IDT sound as it seems many do, I checked my BIOS ver IDG4511H.86A.0090.2008.0924.1800, as you can see its IDG4511H, not IDG4510H, I have searched the internet high and low and all the updates seem to be for the IDG4510H and not the IDG4511H. Does anyone know how or where to obtain an update please.
I'm sorry to say this, but you do not have a retail or bulk version of the DG45 series desktop board. The BIOS string indicates that you actually have a system OEM-brand-specific version of that desktop board. You should contact the company that originally built your PC (most likely Advent) to obtain a BIOS update, in this case.
