Does AppleTV(v2) output 24-bit audio through TOSLINK port?

I have some high-definition audio files (24-bit/44.1KHz and 24/96) in Apple Lossless format. I also have what I thought was a simple question: Does the AppleTV support bit-perfect playback of such files?
Posts on other forums suggest that the AppleTV downsamples everything to 16/48 (which would be absurd on Apple's part, as every other link in the audio chain, including iTunes, Mac, DAC, etc fully supports 24/96).
Can anyone confirm either way? The technical specs are conspicuously silent on this issue...

Thanks for this, Alley Cat. Very helpful reply. Have you indeed confirmed that the ATV2 outputs everything at 16/48, no matter the source? If so, how?
Daft is exactly the right word! 😉 Does anybody at Apple read these forums? Why would Apple make the ATV the only weak link in the chain?! iTunes fully supports high-def audio files, and the ATV obviously should too... As you've noted, the ATV can and should offer bit-perfect playback, period.

Aaaargh, I was thinking of getting one of these as a more convenient way of getting 24/96 sound out of my macbook than a long TOSLINK cable to my amplifier.
Looks like another wasted opportunity.
What I don't understand is that according to other reports, digital audio from a DVD is passed through no problems. Why would a 5.1 digital signal be untouched, but a similar signal from iTunes be screwed up?
There must be some sort of workaround?
And why, in 2011, is 24/96 still considered 'audiophile'? After 30 years of 16/44.1 you'd think we would have moved on somewhat to a new standard.

Because most commercially released music is originally recorded at 24bit at either 48k, 96k or 192k.
When digital audio was first being taken up by studios in the 1980's, 16 bit/44.1k was the standard until the early 90's when they upgraded from 44.1k to 48k. Then 16 bits were raised to 20bits then finally 24bits by the mid-late 90's. 96k and 192k were later introduced in 2002. Recently Pro Tools (most commonly used recording professional program) has only just moved to a 64-bit based platform which offers a 32-bit Float recording, however no processor has ever been released by ANYBODY that will handle a 32-bit audio signal.
So 24bit/192k is still THE HIGHEST professional standard you can get.
