Thanks for the New Bios.
What are Xonar models?

Thank you also

Xonar is a line of sound cards produced by ASUS. 

Got it Thanks EVGATech_BrandonS

Is there any other fixes in this firmware update, besides the 2 fixes noted?  If not, no need to apply this then.  Thanks!

I have the same question.

There could be a hidden fix in there or two that we don't know of 
Previous Bios version didn't mention any fixes for the Intel 750 NVMe SSD as you can see here:
 
BIOS 1.19/1.18/1.02 Updates

• Improving PCIE compatibility. (ASUS Xonar Audio Card)
• Improving Keyboard compatibility. (N-Key KB)
• Fix CPU ratio error after resuming from S3.

But still, it fixed an issue where, if performing an EFI/UEFI-install on the Intel 750,
it would just blue-screen during boot-up of Windows 10.

It's a live! It's a Live!!!
 
Xonar finally working properly on Classy. Third time lucky BIOS update.
 
Using UNIXonar driver 1823 version 1.80a r3. Considering the issues X99 has with Xonars I will probably refrain from updating driver version to a newer when it comes. So happy it works. Finally I can run 2 audio/video streams simultaneously without one going wonky.
