LAV Audio and Dolby Headphone

Hello,

I have an Xonar DGX with Dolby Headphone. Dolby Headphone (virtualization) has a 5.1 mode and a 7.1 mode with 3 types of rooms. The 7.1 allows for each speaker to be moved in a 2d plane, which means setting direction and volume.

Can I use the 7.1 feature with a 6 channel source?

For playback MPC HC with LAV 0.74.1 is used. No mixing.
LAV has an option:
Convert Output to Standard Channel Layouts:
Converts all channel layouts to one of the "standard" layouts (5.1/6.1/7.1) by adding silent channels. This is required for sending the PCM over HDMI if not using another downstream mixer, for example when using WASAPI.

Would this help with using a 5.1 source with 7.1 Dolby Headphone?

Thank you.

I did some tests with a 5.1 source upmixing it to 7.1 with Lav.
Lav just moves the Back L/R channels to Side L/R.
Disabled some of the options on LAV audio font panel, the ones related to surround sound, did not change anything.
Also tried the options on the Mixing panel, still same.

FFaudio does not move them at all.

I can create a custom matrix here, but what will happen if I enable the 2 extra channels for 7.1 on a 5.1 source?
