HTPC components

[TURIN]

Thread Resurrection, again!

Right. everything was fine with my set up until I replaced the graphic card (See previous thread) and linked it all up with a HDMI cable. (The previous card only had DVI output and I had the sound coming direct from the sound card with audio jacks into the AV receiver).

I now have problems getting the sound to work. I've disabled the Analogue output and have it straight form the graphic card through HDMI to the AV receiver. It works but the volume indication graphic in MCE freezes.
I can still alter the volume direct with the AV receiver remote.

I must be missing something obvious.

Any ideas?

Thanks.
