It depends

the GT2xx doesn't officially supports HBR ; but it seems to work,
albeit buggy ; that's why it's YMMV.

For some it seems to work for both TrueHD and DTS-HD ; on my machine,
would only with for TrueHD ; the amplifier would show DTS-HD but no
audio would come out.
For someone else, the amplifier lights keep blinking, but audio works.

You do not need HBR support however for E-AC3 and DTS-HD <
6.144Mbit/s... so those will work fine with the GT220

In fact, DTS-HD MA if less than 6.144Mbit/s doesn't require HBR
either, so it should work on all GT220.
