I have a stubborn issue regarding channel mapping: When playing back 7.1 movies the channel layout is correct and when playing back 5.1 films, the side-surround channels are being played back through the rear-surround channels.
My setup is a bit complicated: Kodi renders audio with reclock for conversion to the needed 44.1 kHz. Reclock then plays via wasapi to the virtual soundcard from VB-audio, which then outputs via ASIO to netjack, which then transports the 8 channels to a linux PC doing all kinds of things (FIR filtering, crossovers, compression, volumecontrol).
The setup is working absolutely flawlessly except for this one issue. I did not find any option for channel mapping in the (externally setup) LAV filters except for the "standard layout" and "use legacy 5.1 channel layout" settings which both do not change anything.
Also simply switching the side-surround and rear-surround channels would not work.
Does anyone have an idea what might go wrong here?
