Anyways - if some of you thread veterans care to give a summary of current issues that would be helpful.
Cheers, Damian
Welcome back, Damian
While you were away I got my hands on a suitable PS3 and have ripped the SACDs in my collection. I encountered a couple of issues with multichannel playback (reported way back in the "Support for AE on the Windows platform thread"), so I'll summarise here:
Playback of 5.0 (as opposed to 5.1) FLAC files doesn't work as AE can't find an exact match for the format.
Code:

Album navigation causes reset of WASAPI sink - sometimes:
I have found another issue with the AE code when playing multichannel FLAC audio files. If I start playing an album, xbmc recognises the format (usually 6 channel, 24 bit at 88.2kHz) and sets the WASAPI sink accordingly. If I leave the album play through normally all is ok. However, if I use the up and down arrow keys on my remote in order to skip to a specific track, xbmc will sometimes determine that there has been a change in the number of audio channels or sampling rate and will initialise the WASAPI sink back to 44.1kHz, two channels momentarily, then re-initialise WASAPI back to 88.2kHz, six channels and play the song. This cause a "click" in the relay on my Onkyo AVR and sometimes results in the first milliseconds of the song being missed. This does not happen on stereo (2.0) FLACs, only multichannel (5.1) and then only sometimes. Foobar on the same machine does not exhibit this WASAPI re-initialisation problem at all.

No stable support for Realtek HDMI drivers
Like many others I have been using the Realtek HDMI drivers (in place of the MS ones) in order to get a full 24 bit 192kHz six channel experience on my AMD/ATI based Fusion motherboard. AE + Realtek HDMI drivers = unbelievable video stutter.
I fixed it by removing the Realtek drivers completely and installed the specific drivers from the ATI Catalyst package. Flanger216 has made some comments on Realtek drivers earlier in this thread - http://forum.xbmc.org/showthread.php?tid...pid1141969
High CPU utilisation when playing audio
Normal CPU utilisation when playing live TV or video files, but it goes up >70% if you play regular stereo or multichannel FLAC.
