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.

It's been like a year, I know. I've been away for work and am now back home. It's like time travel, I remember this as if it were yesterday. I got home a few days ago and everything I had to do before I had to pack up and go is back on the table to get accomplished! This being one. So still no DTS. Just tried to watch a new movie with DTS on the Pi, downgrades the audio to pcm pro logic. However Dolby Digital still works. Here is the post I made on Amazon as well as other places, hope U9LTD can help! Or someone, ANYONE! Thank you in advance for any help to get this resolved.

Using the latest version of Xbian and the earlier version of the box mentioned above WITH NO EDID switch. I used hdmi_force_edid_audio=1. Sends Dolby Digital fine to the receiver. However DTS is downgraded to PCM Dolby Pro Logic. I tried different files and ensured the right audio stream was sending through XBIAN. I do know for a fact my receiver accepts DTS.. It is a top of the line Sony Receiver that I have had for years, plays DTS, Dobly, PCM, and all the formats have been used on this box via toslink/optical. I have used DTS before with a blueray player, computer, etc... Is there something else I need to edit in config to get DTS to work? The box in XBIAN next to receiver plays DTS and DOLBY are checked. There has got to be a way to resolve this. Thanks again in advance for your help.
