buggy_aht_5.1_384.eac3 Jan 6, 2008 This is a 5.1-channel sample which uses AHT. This is currently the only sample I have of this type. I do have one other sample which uses AHT, but it is mono. The file plays fine at first, but then reports using enhanced coupling for some of the frames. I do not believe this is the case, but I cannot be sure until I investigate further. Some of the frames do also give other generic parsing errors, which is what leads me to believe something else is going on. -Justin Update: Jan 7, 2008 fixed in SoC SVN r1798 The issue was caused by a bug in the code where the check to see if the coupling channel should be in AHT or not was incorrect.
