 Devices are not opened by an arbitrary string name anymore, but by device instance ID (or magic numbers to request a reasonable default, like a NULL string in SDL2). In SDL2, the string was used to open both a standard list of system devices, but also allowed for arbitrary devices, such as hostnames of network sound servers. In SDL3, many of the backends that supported arbitrary device names are obsolete and have been removed; of those that remain, arbitrary devices will be opened with a default device ID and an SDL_hint, so specific end-users can set an environment variable to fit their needs and apps don't have to concern themselves with it.
