DTS output through SPDIF with onboard Audio help!

[tollanaram]

Hi, Sorry to post a question that I'm sure has already been answered!
I've searched the site for hours but can't seem to find a conclusive answer.

I have a Foxconn P4M9007MB-8RS2H mobo that has onboard 7.1 output.
I have this connected via TOSLINK to a Pioneer VSX-817 amp which is DTS compatible.

However, when I try to play a DVD disc and select DTS on the DVD menu, the amp displays that DD 5.1 is inputted - not DTS!!! I presume the mobo can output DTS, but I cannot any literature stating whether it can or cannot!!!

I'm using the default MS audio decoder.

Any help would be appreciated!

Try this:

1. Right click the speaker icon (in the tray) and select "Playback devices"
2. Right click on your playback device in the list and select "Properties"
3. Select the "Supported Formats" tab
4. Ensure DTS is checked

Hopefully that works.

Tollanaram,

I assume that the 7.1 on your motherboard is the analogue output at the back of the motherboard. It might be the case that the source material you are looking at is only Dolby Digital 5.1 and that is being reported by the digital output to your amp as DD 5.1

Do you have the latest drivers for your audio, and what settings have you set on your audio?

Unfortunately I've already tried this - sorry, I sould have mentioned that in my first post!
I have "DTS Audio", "Dolby Digital" & "Microsoft WMA Pro Audio" all selected & if I press "Test" for each one I get sound!!!

I will leave only "DTS" checked and see if that heps!

The problem may lie with AC3Filter - do you have that installed?

I can't remember the exact settings - but check each tab in the AC3 filter configuration dialog, and try setting AC3 and DTS to "on" under the "SPDIF Passthrough" section.

Also check the "Output format" settings and select "use SPDIF".

*UPDATE* I rechecked the Audio Properties, selected "DTS" only (deselected Dolby Digital & WMA Pro output) & pressed "Test". I watched the amp carefully and as Vista played its beeps for each speaker, the amp showed DTS! I'll try a DTS DVD disc later!

I'll check I think so; I believe it was installed with Vista Codec Pack - it have will have to be later coz my kid's are on the VMC PC watching "Surf's UP" (now that's a completely different subject - wow is that one strange movie!!!)
Another question- if I leave "DTS" only checked in Vista Audio Properties, and set AC3 to DTS will I experience full 5.1 DD on DD 5.1 only discs?

It should drop back, try selecting DD as well as DTS and then do a speaker test and then select WMA Pro and check each again.

another thing to check which i did install and all worked fine was a high definition audio driver for my mother board i have 2 media centres and both have dts working

THANKS!!!! I did have AC3Filter installed - I followed your instructions, popped in a DTS disc and - WOW! - it worked! My amp displayed DTS as it should.

THANKS!! I did this before configuring AC3Filter and now I've got DD & DTS output!

The only problem I have now is that I've never experienced DTS before and it's so much better than DD - crisper and seems to be a better "all-round" sound (if that makes sense!). This means that I'm going to have to re-encode my ripped DVD's with DTS to remove DD in favour of DTS!!! (I know DTS takes up more space as it's not compressed, but I gotta have it!!)

Thanks to all for your help!

That's great

Good to hear you've got it working

Enjoy!
