I recently installed Win 7 64 as opposed to the 32bit I had running.
I no longer get sound.
The PC in my sig is hooked up to my Onkyo receiver through HDMI which in turn is attached to my SHarp LCD through HDMI. The first attached screenshot says I have my HD audio using S/pdif but I am not using S/PDIF.
My old graphics card, a 9500 GT is getting sound from a little 2 pin connector to the mobo and HDMI is the only path. This setup worked fine prior to the OS change but I had a different sound option in attachment 2, not including the spdif in it and I can't remember what it was called, which is irrelevant as it is not shown in attachment 2.
Any help appreciated!
