Just use the install method without it. (See readme)
I personally use it for custom dynamic range control.
BTW: On my setups i never bitstream audio. I love LPCM. :-)
I have a 7.1.4 setup, so I have to use bitstreaming if I want Atmos or DTS:X information. It's 100% a deal breaker if it doesn't work properly.
Fortunately, I think I've fixed bitstreaming for all formats (had a false positive yesterday).
To begin with, the "without AC3Filter" batch file still actually installs AC3Filter. The two batch files are identical. I'm not sure if this was a culprit for me, but you probably want to not install it to begin with. Just uninstall and registry clean if you ran this and didn't want AC3Filter. I also can't guarantee the rest of this guide works with AC3Filter installed.
First, go into LavFilters_x64 directory and run the Open LAV Audio Configuration.bat. Check all formats your receiver supports. This may not matter, but it can't hurt. Almost all other settings can be played with if you need to, however you MUST check the
Enable System Tray Icon checkbox. You'll see why later.
Secondly, open Kodi. Go to Settings >> Player >> DSPlayer, make sure Audio Renderer is set to Internal Audio Renderer (Sanear). Set the Device to your receiver. For me that was
DENON-AVRHD (NVIDIA High Definition Audio).
Enable
Exclusive Mode,
Allow Bitstreaming, and
Ignore System Channel Mixer.
Play a movie. There's a good chance bitstreaming is still not working... if you think it is, make sure you check both Dolby Digital/Atmos
and DTS files. Bitstreaming worked almost immediately for ac3/DD+/Atmos, but didn't for DTS(any flavor). If all formats are bitstreaming you win! Stop reading.
If not everything your receiver supports is bitstreaming you still have work to do. You can ignore the "Allow Passthrough" on Kodi's Audio and Subtitle settings menu of the video player. It seems to be completely ignored. While the movie is playing hit the windows Key or something to bring up the task bar. Open the system tray and click on the blue LAV Audio Decoder icon to bring up the properties. Your bitstreaming formats may be unchecked again. Re-check them all. You can enable "Fallback to PCM if bitstreaming" is not supported, but I can't verify if that works properly. Apply and Close the properties.
Stop your playing movie. Restart your movie. Bitstreaming should now be working.
