The title is completely misleading.
I gave up getting the ALC 1150 onboard audio for my Asus Sabertooth Z97 Mark 1 to work under El Capitan.
I bought this puppy from Creative, one of their USB Sound Card's from Amazon. I suddenly have sound which doesn't drop out when I put the Hack to sleep.
The Sound Card is called "Creative Sound Blaster Play! 2 USB Sound Card with SBX" and clicking the link takes you to Creative's website.
