I have a Razor Thunderbolt 4 dock (https://a.co/d/gqRt8BC). Charging (90W), displayport via Thunderbolt (one monitor 4k@60Hz), USB, the SD card and the audio out all work. It works with both Linux on my Framework and OSX on my macbook pro.
Interestingly, the audio device only appears when you have something plugged into the combined mic/earphone jack. This is clever, as you can’t have the audio output going to the device when there’s nothing plugged into it.
