HDMI Sound issue (htpc)

For the below system:

ABit IP35 Pro

Q6600 & 4G

MSI 8600GTS w/hmdi audio in

Creative Xfi w/Front Panel

At one point, working off Vista 32bit, I was able to setup the pc, audio cable from the 8600 to the front panel of the Xfi, plugged the hdmi cable from the 8600 to Samusung TV - and the audio was fine.

After a long while, the OS was acting up on other fronts, besides which the audio was breaking up. Like it would have a gap, then you`d hear something breifly, then it`d cut out - and repeat. (all the while, sound through the 5.1 speakers was fine).

Since this/then I had reinstalled the pc using Vista 64bit (using latest Vista 64bit drivers for everything I believe), and I tried the TV in the same way and got the same cut in/cut out - cut out being the longest period.

I happened to "play" with the creative audio panel on the desktop, switching the spdif from something like 48khz to 96, and now the trend is almost reversed. Cut in/cut out - only the longest period being when it cuts in.

Obviously an annoyance now. TV sound works fine btw.

So it seems to me the frequency of the output of the spdif is the issue. It`s highest setting is 96. Although I did see somewhere in it`s settings about 128 (or similar) for something else.

Now, am I to assume that the HDMI output is required to be in excess of 96 in order to get an uninterupted sound ? (this is with either playing something on vlc or simple audio on wmp, no codecs installed to this point)

As I said, a whole while ago, it simply worked and I didn`t play with anything.
 
Creative`s console isn`t the most ordered of preference utilities.

The 128khz happens to be 192khz, and it`s for the Speaker output options - nothing to do with the spdif so it seems.

The only thing I can see to change here is to set all the outputs to 96, spdif, "what u hear"??, and whatever.

I know if it`s set to 48 - it`s cut-sound city. 96 is like almost there...

If it doesn`t work, I`m going to have to see if the driverset I got for the 32bit install differs to the 64bit (which I don`t think it does, it`s just Vista afaik), and perhaps see if they`re older or something - try em. - pfft.
