Hi Dear DanielaE.. you doing a great job. i just have a question for you and it may sound stupid, what are the possibilities of enabling bitstreaming in the music player, is there any workaround to bitstream music files ie: mp3, flac, wav etc...

My $0.02

Just finished building my HTPC based on an AMD A6-3650, Asus F1A75-M mobo and Win7.

I have an Onkyo TX-NR609 receiver and bitstreaming works ok. Just tested a few files with
this special build (thanks DanielaE !!!!):

- MKV container with x264 and Dolby TrueHD works fine (TrueHD icon lights up on receiver, so definitely no "core")
- MKV container with x264 and DTS works ok
- MP4 container with x264 and AAC audio works ok, PC decodes to PCM, then streams PCM over HDMI to receiver
- AVI container with XVID and MP3 audio works ok, PC decodes to PCM, then streams PCM over HDMI to receiver

I don't have rips with MA, so couldn't test those.

Daniela can add to this, but here's a synopsis:
- mp3's cannot be "bitstreamed" they must be decoded as they are in the frequency/time spectrum, not amplitude/time, and need reconstruction at any rate. However they have no bitdepth, and can be decoded to any bitdepth, which in XBMC without AE is at 16bit. AE decodes them to float, which gives greater resolution.
- 16bit flac and wav are already bitstreamed as long as you have the volume in XBMC and Windows at 100% and are using exclusive mode for WASAPI. XBMC without AE cannot output higher than 16bits at this time, so 24bit flac is degraded in quality

That's the status now, maybe Daniela has something in the works?

Hey loekf, I have the exact same receiver as you! Can you try playing my 30 second star wars clip? it's dts es and won't play for me.. I thought it was daniela's build but I'm not sure now.. my htpc is a mac mini with intel hd 3000 graphics running windows

star wars dts es http://tinyurl.com/6nxe348

Here's a dts hd master audio clip that bitstreams great for me with daniela's build

I tried out DanielA's xbmc built on my other computer with built in intel hd 2000.. with some usb headphones and I notice there's weird clicking in the sound for both the star wars and tron legacy videos I posted.. but they play the video fine.. whereas on my intel hd 3000 mac mini the star wars video won't even play.. stops after a few seconds

Thanks. Quick test:

- The Star Wars file just stops after a few secs, no sound
- The Tron file plays fine, with DTS MSTR lighting up on my receiver

Not sure why DTS-ES doesn't work on my system. Maybe it's the XBMC settings ?

Some results from me:

Used GPU: ATI HD5450
AVR: Onkyo TX-NR3007
OS: Win7 x64

First tried with XBMCSetup-11.0+HD-audio - no luck - video stuttered - audio had hickups

Then XBMC-AE-20120406 - runs fine, tested DTS-MA (from . iso) and DTS High Res from mkv

XBMC-AE-20120406 was simply installed over existing EDEN final.
I am not sure anymore how I installed XBMCSetup-11.0+HD-audio - might be this was a complete clean install.

Thanks for making HD-audio possible :-)))))
Realy great job.

Agreed - pls keep this thread for the HDAudio patch and refer AE feedback to: http://forum.xbmc.org/showthread.php?tid=124600
