PowerDVD SPDIF problem - Who can help?

[Russtavo]

I hope someone can save my sanity and help me with this problem! I have my new HTPC connected to my amp with Coax S/PDIF. Applications such as Windows Media Player are working great, sending the correct multi-channel streams as my amp displays "Dolby Digital" or "DTS" depending on the source. One major problem: PowerDVD outputs NO sound whatsoever when I change the audio settings to "S/PDIF". If I set it to anything else (e.g. "2 Speaker", "6 speaker") I just get stereo sound. My suspicion is a compatibility issue between PowerDVD and my X-Fi Sound Blaster drivers, but I dunno. Here's my system spec:

PC: Dell Vostro 200 Slim
OS: Vista Ultimate 32-bit SP1
Graphics: ASUS Radeon HD 3450 (Catalyst 8.2)
Audio: Sound Blaster X-Fi Xtreme Audio (latest drivers)
Display: Sony Bravia KDL-32D3000
Amp: Denon AVR-3802
PowerDVD Ultra: 7.3.3730.0
LG GGW-H20L Blu-Ray/HDDVD Combo Drive

I have disabled the onboard Relatek audio, and disabled the High-Def Audio on the graphics card.

I've done screengrabs of all relevant settings/info, they are here:

I've e-mailed Cyberlink support but they are s-l-o-w, and not helpful. I want to play Blu-Ray and HD-DVD discs, so I really need PowerDVD to work. Any help from you geniuses is really appreciated!!

Right string maybe, but the wrong yo-yo

Hi,

As much as we'd like to be the master of many trades, this one belongs in a different forum and not here at SlySoft.

I'm having the same problems

Hi,

I've given up on the SPDIF bypass in the "SPDIF Input Settings" tab on the Creative Audio Console. As soon as I select "SPDIF bypass" I get no signal, no matter what Windows and PowerDVD settings I have selected. I use fibre optic cable so this is how I know about he signal not being sent to the speakers.

When I use the "Default Setting" in the Creative Audio Console and do the Windows audio dts channel test I get dts audio. Hence I believe that when using the X-Fi hardware and the Windows Media Player, with dts activated, you will actually get perfect dts which is music to my ears.

Also I know when dts is being sent to my speakers as the Logitech Console displays the format of signal being sent through.

Cheers
