Hi everyone!

Working on my ASIO music player plugin, i'm investigating possibilities to provide better support for DTS/DD passthrough for My Music. However, i don't own an external decoder myself, so i'd like to ask ppl who have to do a little test for me. Implementing my new plan in the plugin is gonna be some work so i'd like to know if it works before doing a lot of work for nothing

Here is a little testprogram spdiftest.zip, that should be able to play a DTS/DD encoded wav over s/pdif. Usage is simple:

Unzip it to your desktop (or somewhere on a local disk)
Launch spdiftest.exe
select the file to play
Select the device belonging to your s/pdif output
Hit the play button
Let me know if this works!

Some test material can be found here:

I'm also interested in what happens if you play a normal stereo wav (CD rip). Does the decoder reject it as being invalid or does it play as well? Also, i'd like to know if this works on Vista as well.

If this test is successfull i will implement it in the plugin allowing more ppl (this actually should work on all devices supporting AC3 passthrough) to play DTS/DD material from My Music.

Thanx,
Symphy
