    I've done plenty of searches, but can't seem to find a definitive answer.

    Am I right in thinking it's down to support in the audio drivers?

    I'm trying out a Abit Fatal1ty F-I90HD with PowerDVD Ultra, but there doesn't seem to be an option (that I can find) to enable me to passthrough a digital signal to my amp.

    I'm no expert but the Trust card I have in my Vista Media Center works great with the drivers on http://cmediadrivers.googlepages.com/faq for SPDIF, but with the Trust drivers definately does something to the sound stream as it does not sound anything like as good.

    PS thanks to xxxx for the link to the drivers in this post

    Yes, that's right. I have an Abit AV8 board with 7.1 onboard sound and have installed Realteks 32bit Vista drivers and Realteks HD drivers and can get SPDIF pass-through no problem.
    You're right in not finding an SPDIF option in PowerDVD because there isn't one. You have to enable SPDIF in the sound options in Windows control panel

    As far as I can understand it, the official Trust drivers reduce the signal to 14-bit, which is why DTS wav pass-through won't work. The other drivers you mention bring it back up to 16-bit.


    My pleasure. Above all thank the bloke who wrote them. First class job. :clap:
