I have just built an i5 rig and can't get the audio to work over the HDMI, I have seen many posts but none of the solutions seem to work for me.
1) Realtek ALC888 onboard audio - R240 drivers
2) A 9600GT with DVI to HDMI adapter - 195.62 drivers. (Tried the 181 drivers as well)
3) Patch lead from SPDIF out socket on the motherboard to the 9600GT card
4) Motherboard is a Gigabyte P55-US3L
If I select "Realtek digital output" in playback devices the level bars are moving as they should but obviously there is no audio from the monitor. I have seen a few posts mentioning an ATI HDMI Audo device, is there an NVIDIA equivalent? If so I haven't got one and can find no reference to HDMI audio.
In the NVIDIA control panel it shows my monitor as audio enabled but I can find no other settings to do with HDMI audio. I have plugged a bluray player into the monitor and the sound is fine so that discounts a faulty new monitor. Any ideas peeps........
