DTS audio is not passed through when connecting HDMI to TV

When the boxee box is connected to the tv via hdmi, and the tv connected to a DTS receiver via optical or coaxial digital connection, DTS audio is not passed through. This was originally broken on 1.1.0.19053 and then was fixed on 1.1.2.19250. Now it is broken again on 1.2.0.20151. The ticket I submitted for it the first time is at BOXEE-9761 . DTS still works fine if i connect the boxee box directly to the receiver via an optical digital cable. If i uncheck DTS support under the HDMI settings on the boxee box it downsamples DTS to prologic2 and I do get audio. Dolby digital still passes through properly. The problem is exactly the same as the previous issue.
