I have started a Linux thread here: http://forum.xbmc.org/showthread.php?tid...pid1070552
The Windows thread is here: http://forum.xbmc.org/showthread.php?tid=124600

Mods, in order to keep this thread clean perhaps the first post can be updated to reflect these two other threads. Hopefully erhnam won't mind.

Yes that is correct.

For those interested, over the last day a heap of fixes have gone in to correct pass-through issues, such as:

* random crashing
* choppy/stuttering output on some DTS files
* buffer overflow bug causing a sync calculation issue
* 2.0 streams will no longer be encoded to AC3

A patch from DDDamian has also been merged that should fix things somewhat under windows.

We expect to have AE merged into master very soon as we gear up for peer review and then merge.

Hi gnif,

DTS-HD (or anything else passthrough) still doesn't work for me.

I've tried HDMI, and custom hw:0,9 as well as hdmi:NVidia for passthrough but always get this error. The applicable part of the log looks to me to be:

14:37:40 T:140249841436416 INFO: CAESinkALSA::Initialize - Attempting to open device hdmi,AES0=0x06,AES1=0x82,AES2=0x00,AES3=0x0e

Full log can be found at http://pastebin.com/ekSTZy5R

I hope this is a bug and not something I'm doing wrong...

@cdhesse
Its not a bug sorry, this is ALSA failing to open the HDMI output device, you need to get that fixed before any HD content will work.

Progress update:

* Wrote a little buffer class to replace manual buffer wrangling with with bounds checking, should help prevent buffer overflows in future and help identify them when they do occur, it have already identified a few problems that have been corrected.
* PAP is now playing things properly again, of special note is streams with infinite length (streaming radio) or non-indexed audio files (captured audio).
* Don't know if I mentioned this one, but I added S16 -> Float dithering using both normal and SSE intrinsics, this should improve the dynamic range of S16 audio considerably (so I am told).
* Pass-through seems to be fully functional under Linux, need more testing to confirm this though.
* Changing the output device now applies the setting instantly again, this was broken in an earlier merge.
* PAP now continues onto the next song properly on streams with invalid total times
* Merged working OSX code (someone needs to test this)
* Disabled pulse audio by default (until it gets fixed)
* Merged WASAPI fixes from DDDamian.

Progress update (wow, this is new, there is usually a 1/2 dozen or so posts between my updates):

* AE has been updated to master (windows and OSX projects broken, awaiting fixes)
* Mute now toggles correctly
* Volume level is saved and restored correctly
* Rare deadlock issue when PAPlayer stop button clicked has been fixed

We are getting VERY close now people, the merge with master is one of the last large leaps before AE is merged into master! Its been a long journey but we are finally at the end. XBMC developers are now actively testing AE as we nut down the remaining bugs.

IOS/OSX is working in AE now also (except the broken build files from the merge ofc), which is awesome, there are no major blockers preventing AE from merging into master any more.

This doesn't mean that AE is finished, it just means that AE will become part of the nightlies and it will force all the devs to deal with AE, exposing bugs and allowing us to get it rock solid for the next XBMC release.

Good work Gnif and all the others behind the scene!
Looking forward in the release and the joy it will bring to the whole XBMC scene!

Again, Congrats from me

Nice work! Maybe we can update the first post of this topic to summarize the high level changes? new formats, separate AE library, windows, osx and linux improvements, etc? What do you think?
