Unable to play HE_AAC

Infuse pro 5.

Video playback is fine. It has background music, but no talking.

I uploaded a sample: sh2sg.HE_AAC.sample.mkv

What type of device is your Apple TV connected to, and what are your audio settings in Infuse and Apple TV?

With Infuse set to Auto, and the Apple TV set to Best Quality Available your sample appears to play correctly for me (with voices). Also tried on iOS, and it seems fine there as well.

More info on the available audio options can be found here.
