ok im new to compiling and this thread but have been following it it closely for ages. Im not sure if im posting in the correct place as i think this problem occured in XBMC beforehand but seeing as you are developing a new audioengine i thought it would fit in here.
So ive compiled from your latest source running under Linux (Maybe i should post in the Linux only thread?) With regards to HD audio, that seems to be working great for this files I have tested (DTS-HD MA, TrueHD)
The problem ive noticed seems to only be with Dolby Digital 2.0 sources. If I allow my receiver to decode DD2.0, during quiet scenes, where there is low background noise when someone stops talking etc, the sound cuts out completely, then comes back as soon as the level increases. Its almost like the sound is being passed through a really heavy noise gate and its cutting off all sound below a certain level. Its very noticeable especially when people are talking quietly and there is background music, when they stop talking, the sound cuts out and it ruins it. I hope that explains what i mean and you understand.
At first I thought it was my receiver, or the file i was playing, but I have now tried multiple files, weekly TV shows that I have and its the same. Its also the same when using a different receiver so I can rule that out (Although the receiver is the same brand, Onkyo, but completely different and ages)
The strange thing is that when I tell XBMC that I dont have a DD capable receiver, so that it decodes the stream internally, the resulting PCM stream plays back fine, no dropouts or anything at all, and I have tested that again with multiple files.
I dont want to start a war by having posted this in the wrong section, and its not a support request, just something that bugs me massively and I hope it can be fixed with your new audioengine.
If you need me to provide logs or anything please let me know.
I am running under Linux, and use a nVidia GT 520 for HDMI sound and video output. I have also tested this on a machine with nVidia G210 card and the same result occurs. I am using an Onkyo 809 receiver and I have tested with an Onkyo 807 receiver also.
