I've asked this before, but at that time there were actually no decoders capable of dealing with a 8-ch AAC file, created with FAAC 1.25.
Although FAAC is hardly what we would use for everyday AAC encoding, it still is the only encoder capable of more-than-6-ch encoding (1.24 allowed up to 64 ch, which I tested and encoded perfectly, but of course could not be played, while 1.25 allows up to 33ch + 1ch LFE). And the stream was perfectly decoded by FAAD back into 8-ch.
As many AAC decoders are FAAD-based, I asked if there was any that could deal with 6ch+ streams to find there were none.
But now I've come to find that the latest PowerDVD audio decoder CAN decode an 8-ch stream MP4 AAC (using PowerDVD or let's say BSPlayer with Cyberlink Audio Decoder output).
So now I was wondering again if there were any decoders outthere capable of 6ch+ decoding besides Cyberlink's
* I'm using an Audigy 2 ZS. The MP4 AAC requires some channel mapping prior to encoding and the LFE and SL channels are swapped beyond possibility of fixing but beside from that, everything else works perfectly.
Edited: here's a sample of the file that PDVD decoder can play
