There's still a lot of dedicated audio interfaces for people who are involved in making music. However, most of those people are using Macs because of how better CoreAudio compared to ASIO or anything else, and subsequently, because most of software is developed and tested first and foremost for Macs thanks to network effects. And most mac users have Macbooks, which means that majority of usually used audio interfaces are external ones. As for people who just listen to music, IMO, built-in audio interfaces or just digital Bluetooth headphones have been good enough for a very long-time in digital-audio conversion.
