Hello Michael,
Sorry for not getting back to you sooner. I can confirm uninstalling the ATI HDMI Audio driver and installing the Realtek ATI HDMI Audio driver was successful in displaying the uncompressed HD audio option.
Please let me know if you require any further details or testing.
Regards,
Andrew

Hello Michael,
The Uncompressed HD Audio option is not available under the 'Output Mode' when playing back a DTS-HD-MA Blu-Ray. The only options available are 'Non-decoded Dolby Digital/DTS audio to external device' or 'PCM decoded by PowerDVD'.
Regards,
Andrew
