AAC 6 Channel Audio plays slow

Description
After troubleshooting this with people on IRC, I was convinced to open a ticket. When trying to play a .mkv (maybe others) with 6 Channel AAC the audio plays back slow (maybe half speed (?). At this point I am not sure how to create a sample, but soon as I figure it out I will attach one.
Upmix is set to Passive and I have tried Stereo and 5.1 setting. 5.1 has no audio and stereo plays slow. AC3 and DTS passthrough is set on.

Could you please try the mythtv-hdaudio branch and report if this problem is fixed for you ? (it should be)
I have a sample file here: http://www.mattsshack.com/sample.mkv The sample file was made by using: dd if=infile of=sample.mkv bs=1024K count=50 The sample.mkv reports the wrong time on playback but still has the same slow audio problem as the original file.
Let me know if I need to provide any more information or test. -PK
