My experience: Setting PMP to SPDIF tells it to use the SPDIF output of your PC, which you are not using. This means things like HDMI negotiation on supported codecs, passthrough vs transcoding audio, etc may not function correctly.
If I set PMP v3.0.0.24 on my PC to SPDIF it sends no audio via HDMI. If I change PMP to use HDMI, audio functions correctly.
Questions / Suggestions:
-
What make/model of TV? Double check tech specs to see which codecs are supported.
Double check settings to make sure it will correctly pass audio via SPDIF. -
When Device Type = HDMI, what are your choices for Channels and Device in PMP settings?
Suggest setting Channels to 5.1. Device will depend on your PC hardware/software.
On my PC is shows the NVIDIA graphics card and Realtek optical outputs (on motherboard). I choose the NVIDIA graphics card, since I’m using that HDMI port to pass audio & video to the attached TV. Pic below.

For troubleshooting purposes, take the optical connection out of the equation. If you disconnect the optical cable and use TV speakers, to you hear things OK for AC3/EAC3/dts audio?

What happens if you use the non-preview version of PMP?
FYI, VL260M is the model number of the Vizio TV attached to the HDMI port on the Nvidia GPU.
