Hi,
I recently stumbled upon an odd problem concerning mkv files that contain an AC3 Stereo audio layer ("Dolby AC3 48000Hz stereo" for instance).
Every time there is an almost silent scene, my speakers crackle (almost sounds like the audio stream broke down), remain completely silent,
until something happens again (audio wise). The audio stream is then being broadcasted perfectly fine, until there is a very low volume scene
once again, introduced by another crackle.
Sometimes, those "hard fades" occur 4-5 times in 2 seconds, which makes them quite annoying.
My audio is being streamed directly over HDMI.
I then reproduced that behavior with Media Player Classic without a hassle.
After some digging, I found out that once I enabled the AC3 (S/PDIF encode mode) within the ffdshow Audio Decoder Properties,
the crackling stopped and my mkv files played fine within MPC.
Trying to get ffdshow working with XBMC, I installed the DSPlayer Version of XBMC Eden (I still used Dharma until that point).
After several xml-config changes, my "crackling affected" mkv-files played fine.
Unfortunately, everything else seems halfway broken now.
Video files with an AAC audio layer crackle 4 times every second, XBMC hangs itself up after starting a video file, etc.
I now rolled back to my old version of XBMC Dharma and am wondering, if there was any other way to get rid of that annoying crackling with that one type of mkv-files.
My Setup:
OS: Windows 7 64-bit
GPU: AMD 6450HD (also happens with my Nvidia GTX 570)
AVR: Onkyo TX-NR509
I already tried every option within my AVR's menu and the XBMC system settings without luck.
Could it be, that my receiver can't handle those low volume AC3 audio stream spots and stops streaming, because they are too low to be
recognized as actual AC3 stream (this only affects stereo AC3 streams though)?
Did anyone happen to have a similar problem and was able to fix it, without messing up everything else? :confused2:
Any advice would be appreciated.
Thanks in advance!
