No LFE output without Center channel
- PipeWire version:

Procedures:

Description of Problem:
I have a 4.1 setup using 3 minijac outputs from my soundcard. The center/sub output is connected directly to my sub with both L and R.
If i set profile to 4.1 or 2.1, Center is correctly heard from the front speakers but LFE is nowhere to be heard.
But if i set profile to 5.1 or 7.1, both Center and LFE can be heard from the subwoffer.
Speculation:
It might be that my soundcard expects only the setups exposed in windows, where you can only chose 2.0, 4.0, 5.1 or 7.1. But in windows you can disable the Center speaker after selecting 5.1, so every program thinks the system has 5.1 but windows moves the Center output to the front speakers. Is there perhaps a way to configure a 6 channel 4.1 where pipewire is configured to 4.1, but adds a silent Center channel before sending it to the sound card?
