Static / Whining noise behind driver seat

[nikmk5]

Hey everyone! I really love my car but there’s this constant static/whining noise that’s driving me crazy. Every time I start and sit in the car, I notice it, and it’s getting really irritating. I feel like it’s coming from behind the seats (not sure if it’s the speakers)
Has anyone else experienced something similar and managed to fix it?
I
I’ve attached a sound clip for reference (please listen by holding close to your ear and at max volume. It’s very faint) and I’ve also deactivated ASD using BimmerCode.

Any help would be greatly appreciated!
Thanks

Hard to really hear it.
Fuel pump?

I know exactly the noise you are talking about. I had it on my original 2021 Supra when I deactivated the ASD, only solution I found was to reenable it. I actually recently got another 2021 Supra and this one didn't have the issue so I guess only some do it?

Cannot really hear it.

Mine (2.0) sometimes does a high pitched noise that I thought it was from the diff, but I am now 95% sure it comes from the speakers.
I discussed it here at the time: https://www.supramkv.com/threads/whining-electrical-noise-from-differential.35217/

It came up again a couple of weeks ago and tried to record it: video attached. You can hear the intermittent high pitched noise. Very faint as well. ASD hasn't been disabled.
