Hi everyone i posted here because i'm having some problem with the audio of the gigabyte z77-d3h mainboard.
I have followed your guide tim but i can only play sound from internal speaker device without any success from the optical in! Actually the optical in is correctly showed in the sound panel but if i select that source i cannot ear any sound!
my spec:
Gigabyte z77-d3h mb
intel i5 3570k
8gb ram corsair
90gb corsair force 3 ssd
the main-board have bios f14 and rev. 1.0 All bios setting is standard except for:
1) hdd mode set to ahci
2) controller of usb3 is set to smart-auto and all port to disabled.
That's the things i have done:
1) install ML 10.8 via unibeast
2) upgraded to ML 10.8.2 via combo update
3) select userDSDT - DSDTfree installation from multibeast and installed the LAN kext
4) Rollback the AppleACPIPlatform.kext
5) restart and the system works well (except, obviously, for audio)
6) installed your DSDT then restart
7) installed patched Applehda and VIA2021.
At this point i can't see any audio device in the audio panel then:
1) removed all audio kext
2) repair permission then restart
3) installer ORIGINAL applehda.kext
4) repair permission then restart
5) manually patched the applehda following the step of
http://www.osx86.net/view/3041-via_v..._applehda.html
6) installed via2021.kext and restart
after that i arrived at the situation i explained on the beginning: working sound from internal back panel but no sound from optical out. In the sound panel is correctly showed the optical out but if i try to select it i can't ear any type of sound!!!
I don't know what to do, this is the last problem that divided me from having a fully operational hackintosh, so please help me!!!
If some other detail are needed i am here! thx a lot guys.
