Hello all, I just got a Mac Pro 1,1 (flashed to 2,1) about a week ago, and have already got everything set up. However, one thing has been bugging me, the sound. I installed Windows in BootCamp and noticed that the ATI Radeon HD5770 actually outputted sound to my TV in Windows. I wish to achieve this is OS X, and have already tried installing an HDMI audio kext from another thread here. This is an official Mac card, and the Mac is running El Captain.
