I'm using equalizer APO for my home theater. It works perfectly for everything but the Netflix. The only way get 5.1 surround sound in Netflix on Windows is in the Netflix app. I got the Windows app for Netflix and it does indeed output 5.1, but it will only bitstream it (aka: my receiver says "Dolby Digital+". Equalizer APO doesn't work with encoded Dolby Digital and needs a decoded signal to perform it's equalization.
So basically what I need: Force Windows 10 to decode Dolby Digital+ from the Netflix app, Equalizer APO equalizes the decoded signal, and the PC outputs the equalized/decoded signal as 5.1 PCM audio over HDMI to my receiver. Is this possible?
