Hey guys
Are there any builds of xbmc with AudioEngine available for the AppleTV 2?
I'm eager to test it! I have iOS 5.1.1

Or does it not work for ATV2 yet?
Cheers

There are no nightly builds for atv2 atm because the ffmpeg version update breaks atv2 compatibility (it would lead to rejailbreaking the device if you would just install such a build on your atv2):

Beside that even if there was a working build - there is no HD Audio support for ATV2 and we don't even know if its possible at all on that tiny platform.

Not yet. When nighties start again for ATV2 you will get the new audio engine changes. But I'm not sure if HD audio works on the ATV2. I'm sure someone can clarify that?

If I have helped you in any way, please forgive me, it was entirely accidental.

from joy reading the news on the homepage, to depression all in the space of 2 minutes. Wonder if the ATV3 will be any different (is a JB ever sees the light of day of course)

according to the apple site, the audio from the ATV (both 2 & 3?) are:
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

That doesn't seem to include anything more than DD 5.1. bummer

Peace,
Fritz Boyle

for what it's worth .. ATV2 with eden plays fine (in terms of audio at least) clips from here

dts-hd and dolby truehd are properly identified judging by the icon shown in the osd and I get a regular dts/dolby output on the optical. My receiver is not HD-audio aware so it just detects and plays them in plain dts/dolby

DTS-HD and DolbyTHD cannot be passed via optical so the ATV must be downsampling them before bitstreaming to your receiver?

Hasn't anyone tried playing a similar file as above over HDMI to a capable receiver?

Well, I picked up an ATV2 and installed XBMC. None of my bluray ISOs will play over SMB anyway, so for me HD audio is a moot point.

Here's hoping for an ATV3 jailbreak.

My receiver decodes all HD formats.. works with regular BR players.

Also just checked some HD flac files and they are downsampled from 96khz to 48khz.

I don't see how your ATV is passing HD audio.

Edit: (I am using HDMI)

mikey1234 its nearly impossible that hd audio gets passed through with atv2. Well its not nearly impossible - its impossible.
