If it's stupid and it works, it's not stupid
It's hardly any news that several big phone manufacturers are trying to kill off the standard 3.5mm audio jack in favor of their own Bluetooth headphones. And if you want to keep using your favorite wired headphones, they are happy to sell you an adapter so that you can connect them to the charging port of the phone. So a win for them, but if you don't want to play that game, it could be useful to know that - at least with many (most?) Android devices - you can use a standard USB sound card as a 3.5mm audio adapter. I happened to have a couple of them collecting dust, so all I had to do was to plug one in, and it worked! Granted, since it's a USB-A sound card, I also needed a USB-C adapter so it's a rather bulky solution. Not always great when you are out and about, but for connecting to hifi equipment at home, it gets the job done.
