Please try the command I posted before with and without the suggested configuration changes in in config.txt.
The difference of capabilities observed there will bring some light to us on what your adapter is capable to do.

The VHD-H2HSA unit will extra the digital audio signal from the HDMI input. Whatever the format it is, as long as the SPDIF bandwidth can support it. If your HDMI source unit can send it, it will be available at the SPDIF output. Then you need to make sure that your receiver can understand the incoming audio format.

You may be able to validate this by using a Blu-ray player to play a DISC, using the audio button on the remote to select the various audio tracks, from stereo to 5.1CH either DTS or DD, and check the audio coming out of the SPDIF output using a surround receiver to verify.

On the book, SPDIF / TOSLink doesn't have enough bandwidth for DTS master HD audio and DD TrueHD, but it may be case by case.
