Similar behaviour for me on Lenovo T480, though: 1. I have no audio at all through built-in speakers or headphones. 2. Initially, there are no output devices enumerated. 3. After a minute or so, HDMI and built-in headphones devices appear. 4. Built-in speakers still do not appear in device list. 5. Built-in headphones still present no audio. Did not test HDMI. 6. Plugging-in USB audio device is recognized, and functions normally. <-- workaround!
