If that still doesn't work, you can try it with Realtek codeces- High Definition Audio Codecs.

I did download it direct from Nvidia thats why I am at a loss, I will give the realtek codecs a shot. It's very frustrating Frown

I'd remove the device and re-install the nVidia driver.

Hi

Have you checked your screen resolution is a "true HD" resolution 720p, 720i1080p, 1080i etc.? if its anything other than that your audio won't work through the onkyo, i know it happened to me! took me ages to see the obvious!

just a thought, hope it helps.

Not sure exactly what you are saying by screen resolution is a True HD? Do you mean on the HTPC? If I set the resolution to (i think) something like 19**X1080 then everything doesn't fit the screen correctly. But if this is the cause I will definetly give this a shot. I am at the point of trying anything right now Big Grin

Be methodical - if you do not see more than stereo listed as an option you are not going to get DD5.1 or DTS bitstreamed through. Bluray's advice is sound, saying "I don't know, what else can I try" isn't very good troubleshooting.

I agree, it makes total sense, that is one of the first things I looked for. But what I could not wrap my head around was WHY the 5.1 and 7.1 options where now gone. Believe me I am taking all advice here, everyone has been great and I appreciate it, I know I can get it to work as it was working prior to the driver updates. I will do more testing and troubling shooting and let everyone know the results.

Good man - the better the data the more we can help ya here Big Grin

PS your AVR manual is gonna be key here I think. Find or D/L it. I don't know that amp specifically but many won't allow screwing around with Direct modes - things like matrixing 5.1 to 7.1 require DSPs and Direct usually bypasses those.

Cool, Cool, I have gone through the manual and it didn't seem to help out really, but I will check it again. Nod

Hi
sorry, my post was clear to me, i knew what i meant!! Describing the resolution as true hd wasn't very clear, what i meant was on your desktop, right click, go into catalyst control centre. set the screen resolution to 720p if 1280p is too large. that will give you a standard hd resolution which your amp will recognise. I cant see what that resolution actually is, on my phone and no access to media centre at the mo.
it has something to do with HDCP i think. I couldn't get the audio to work originally until i got the desktop resolution sorted.
hope you follow what i mean? Nod
