Problem:
They day before I brought new set of sound system (Onkyo HT-4505) and i try to using HDMI to bring out the video and audio.
However, the audio doesn't come out with the GTX 670, then i try to find the solution on tonymacx86.com
I try to follow many guide but it just to hard for me to understand as a noob mac builder. Any people who has the solution, please help this me. thank you.

the audio doesn't come out with the GTX 670

See Mavericks: HDMI Audio - AppleHDA; 10.8.5 is the same. No HDMI audio until you enable it on your system.

Obviously, what the pdf said and what you did are not the same. Since you are using -x to boot, your system was not ready for HDMI audio. Restore your system from the backup and fix you boot problem; boot is off topic.
