I think what Carpentry said about the ethernet is similar to what some people do when they can't get their Mac App Store working; you have to put a hex code into your chameleon boot.plist. I too have a z97x board and am trying to figure out a way of getting the audio working now.
This worked for me:

You have ALC1150 does the one in multibeast not work for you
What I was talking about and did for them was add deviceID and vendorID to the info.plist inside the kext needed to load their network cards so they could have basic network access before they couldn't even get online what you are talking about is what follows
The easiest fix for the App Store error "your device could not be blah blah blah" is to add a hex String to the either the com.apple.boot.plist or to org.chameleon.boot.plist sometimes I've needed both
So to start off with you'll need an app called efi studio google should pull it up
on the devices drop down select Ethernet then hit add device properties and another window will open with all kinds of stuff you never seen or prolly understand
I always add it to org.chameleon.boot.plist to prevent breaks from updAtes so hit copy hex string to clipboard
then open the file root/extra/org.chameleon.boot.plist with text edit and add the string like this anywhere in the main body
<key>device-properties</key>
<string>Paste here</string>
then navigate to root/Library/Preferences/System Configuration/NetworkInterfaces.plist
and delete it or move to desktop if uncomfortable with deleting
then open system preferences click network and hit the minus sign on each network device
then reboot and re add your network devices in the system preferences and attempt to log in
