@turtle_racer This is how it functioned on my old Oneplus One (R.I.P.), way back on 16.04 - alarms and I think also phone ringing would happen simultaneously through earphones and loudspeaker if earphones were plugged in.
I can see where one might not want it, but I found it a nice feature. I wouldn't know enough to say, but I suspect it was either the way that specific device port was made, or even something to do with the underlying firmware of that device.
I have no sense how hard/easy it might be to implement.
Glad to hear you're enjoying Ubuntu Touch so far. It's been my only smartphone OS ever, since late 2020, and I am continuously just wildly impressed with how good it is and how much it has improved.
