[QUOTE="jameson_uk, post: 745648, member: 11220"] I am not convinced SPDIF can carry AAC. S/PDIF in theory was only there for stereo PCM. Then DVD people managed to trick it into using the same formats but carrying DD/DTS. WMA Pro is similar but I believe there is still very little hardware than can cope with this. S/PDIF probably has the bandwidth to cope with standard bitrate AAC but I doubt it will be able to cope with higher bitrate stuff or multi-channel. Either way I am not aware of any hardware accepting AAC over SPDIF. I am 95% sure that what will be happening is that the AAC is being decoded to PCM and that is being output over SPDIF (so limited to stereo). If you think about it, this is no different to playing mp3 over SPDIF the is decodec to PCM then output over SPDIF. [/QUOTE]
