I am thinking of giving my HTPC a bit of an update. I'm still running an old P4 3.0GHz S478 CPU on a AGP board and although the Radeon 2600 Pro can handle 1080p AVC when dxva compliant with ease, when I have to use software decoding (CoreAVC) it struggles big time. Also I would like to add a Hauppauge S2 sat card to get Freesat HD. Anyway, I don't really want to spend too much as my Blu-ray and HD DVD needs are already taken care of with stand alone players. I was looking at building the system around the GA-MA78GM-S2H motherboard as the onboard graphics seem to be up to the job. However one thing I wanted was multichannel audio over HDMI. I use Slysoft reclock and at the moment have to decode the AC3/DTS, let re-clock resample as necessary (especially when watching a PAL DVD to reduce back to 24fps) and then let reclock encode back to AC3 so I still get 5.1 over optical to my receiver. I downloaded the manual for this motherboard and it states: Please note the HDMI audio output only supports AC3, DTS and 2-channel-LPCM formats. (AC3 and DTS require the use of an external decoder for decoding.) So what's the best option to get multichannel (7.1) PCM over HDMI. A different motherboard or do I need to consider a seperate video/sound card? I do not need bitstream HD audio over HDMI. Many thanks in advance. Rob.
