The price of flexibility is, pi is not opinionated about adding sandboxing out-of-the-box, it gives you options on how you want to do it. You either do it with linux containers, with a dedicated VM, or just bubblewrap.
It is nice that it gives you a way to hook into it in a very easy way though.
The trick I'm using (at least on laptops, cannot do this on phones AFAICT) is to change the input device to the laptop's own microphone to get my earphones to not use HFP (Hands Free Profile) and instead stay in a better quality codec (AAC, LDAC, AptX, SBC, whatever your devices agree upon).
Sound quality for my calls on both sides improved dramatically! Since I've discovered this, I tell all my colleagues in our zoom meetings to switch microphones and it's immediately better for everyone on the call (not just the user that was using HFP).
This is because if you use the hands free profile, it'll use a codec that encodes your voice in a terribly bad bitrate, and even worse, the sound you hear in the headphones is also using a terribly low bitrate.
They should finally fix HFP (Hands Free Profile) spec as it's literally impacting call quality for billions of people.
Edit:
apparently LE audio is a thing, but device support is still terrible.
