RE: [Windows] AudioEngine testers - Windows platform only - Roman_V_M - 2012-04-26 16:18
Just curious: what conditions need to be met to get AAC bitstream via SPDIF? I don't have a fancy AVR with HDMI but my home theater supports AAC via SPDIF, and I have never been able to get correct AAC bitstream on my HTPC with any software. Now in AE build I can select "AAC capable receiver" but it does nothing. AAC stereo tracks are decoded to PCM and 5.1 tracks are transcoded to DD (which is better than nothing).

And: At least the DTS clip plays longer than it is. Just stays at the last picture and counts on...
Hi Hasu0bs,
I wanted to chime in and note that one of my machines is an Acer Revo 3610 with ION, which is essentially a GeForce 9400. It has always had this problem with DTSHD-MA and Dolby TrueHD. Your noted experience is identical to my own. After some reading, the ION/9400 does not handle DTSHD-MA, but will decode TrueHD into PCM. I'm nearly positive this relates to you, too.

I'll try the new build tonight, I also have a Revo, and a Yamaha RX-V3067. If someone could point me in the direction of a (short) clip with TrueHD I could test that as well.

Tonight, I'm definitely going to do some tests with my Onky TX-NR609, AMD Llano-based HTPC and a bunch of clips. I now also have MKVs with DTS MA.

Unfortunately I still get sound drops when playing DTSHD-MA with the new build (XBMC-AE-20120425.exe)
Fewer than before but still I still counted 3 in just over a minute (I let the debug run until I heard 3 drops)
Running win 7 64bit
nvidia GT430
Onkyo TX-NR609

One thing I've noticed in the new build under Audio Settings there's something called "Stereo Upmix"... what does that mean? Does it upmix from mono to stereo? Or from stereo to surround?

For anyone experiencing the DTS-MA bug - another potential cause found and fixed in this build >>DTS-MA test<<
Note that for those not experiencing this there are no new features or fixes to that build, this is specifically for testing by those who's receivers cannot lock on the DTS-MA stream.
For anyone unsure of whether their hardware supports DTS-MA or DD TrueHD: one of the new featues is code to enumerate all your system audio devices' capabilities. They will appear in your log if you have <loglevel>1</loglevel> in your advancedsettings.xml file at start-up. Here is an example from one of my logs:
Device Enumeration log sample
As you can see, we query your machine for each device, it's connection type and name, and supported channels, formats and sample rates. This will indicated whether your machine supports: DTS-MA (AE_FMT_DTSHD), TrueHD (AE_FMT_TRUEHD) and multichannel LPCM (AE_FMT_LPCM).
As a rule, for bitstream support you must choose a device with WASAPI: in front of the name, not DirectSound:, and you must have exclusive mode enabled.

AAC isn't "officially" supported yet, despite the setting, but it will play on receivers that are 100% AAC-capable. I am able to play 5.1 AAC fine over HDMI to a Denon 3808, where it is internally transcoded to AC3 by the amp.

Stereo upmix (previously called All Channel Stereo among other things in XBMC's dark past lol) basically just upmixes any 2-channel non-passthrough source to all the channels selected in your Audio Options settings, e.g. 5.1, 7.1. This will apply to mp3s, 2ch flac, etc.

Damian, you did it! My amp can now lock the dts-master signal!
But: The playback pauses after a couple of seconds because of buffering. After it has loaded for a while, playback continues for a couple of seconds till the next buffering.
Buffering occurs even with locally stored files.
I hope you can fix this issue as well.
Good work, thanks a lot.
Chris

Alright!! Now for this buffering issue can I please get a log. And does it actually show on the screen that it's buffering?
