I still don't know how to query the name of downstream audio decoder.

Here is another update, I included both version, DD+ only and full functiontional DTS/AC3/DD+. If you want to compile by yourself, use preprocessor macro DDPLUS_ONLY.
For the full functional version, I tested ac3filter and sonic audio decoder, with the following samples: AC3 192K, 384K, 448K, 640K, DTS 768K, 1536K, and some DD+. All samples work, and the runtime are also correct, at least on my system.

That dtsac3source version, is it used to passthrough DDP over spdif or transcode the signal on the fly to DD ?

I tried it and get only Stereo. My receiver is not able to DDP, maybe thats the reason.
