If I am streaming an MKV via my Air Video app and Air Playing that to my Apple TV 2, will I be hearing the HD audio, or will it just be regular Dolby digital?

Audio Formats
HE-AAC (V1), AAC (16 to 320 Kbps), protected AAC (from iTunes Store), MP3 (16 to 320 Kbps), MP3 VBR, Audible (formats 2, 3, and 4), Apple Lossless, AIFF, and WAV; Dolby Digital 5.1 surround sound pass-through

The aTV doesn't support HD audio.

as to how air video deals with surround audio, i'm not sure if you'll get stereo or dolby digital.

At the risk of sounding ignorant, can it convert it to LPCM and play that?
