Hey Niresh, Thanks for Wonderful Support of Hackintosh.... Well I have Gigabyte z77 Chipset MB with intel i-5 Proc. & Mavericks 10.9 Install on it. Everything is Working Properly & Fantastic except One thing. My Display Device is Samsung 32" Led Smart TV & I can't get the output sound from inbuilt Speaker of Led TV. My Motherboard Sound is Working Properly. I check for Sound in System Preferences, But there is no inbuilt speaker Option like as in Original IMac in Output Sound setting. Please help me out on this.
