@williamtries There are other issues, some quite annoying, sure, but I haven't had any troubles with calls and call audio on my Librem 5 with PureOS for years now, so I don't think it's as hard as you make it seem. Unless you reach for bleeding edge (I don't see PipeWire stacks as ready for mobile just yet), this is a solved problem; and when you do, there are still some low hanging fruits to reach for in order to solve it.
