You can also hear a minimal noise when it is plugged in. but I can't find a way to activate it in orbit.

I think, inside the AUD it's not just software (data and exe) it also requires config to set the channels (MID + high) on the rear doors for 90 series or one channel per rear door for 60 series. It might require similar procedure like headlight control module when flashing the AUD.
I had a 2022 loaner S60 B5 AWD while my 2019 S60 was in service for sunroof replacement under warranty.
The loaner car did not have HK nor B&W. It had the basic high performance audio and remember there was a center speaker on the dash. So, there is a good possibility that it actually has the center output but VOLVO might have blocked (disabled) it via config or software of the AUD on your car.
However, you wrote that you actually hear very low when you connected the speaker. Depending on how low the sound you are hearing there are only three options.
1) You have faulty wiring or speaker that shorts (most likely)
2) You are missing the negative amp circuit output Positive output of the amp travels trough the speaker and returns to ground of the amp
3) reverse polarity.
If there was no output from the AUD, you could not hear anything at all.
Take a multimeter and measure the voltage (mini Volts DC) of the center output pins when the volume is set to 50%
Do a read out from your AUD software part numbers. Let's compare what you have and what others have.
