Analog ones require the USB host to support it. USB DACs on the other hand only require the OS to support them since they just use standard USB features. That’s much more compatible.
I’m pretty sure the analog ones are the exception, not the rule.
That is correct, and at least part of the reason for that is that most notebooks, and even many smartphones, don’t support them. DACs are so incredibly cheap nowadays that it costs the manufacturer less to put one in the adapter, than to deal with the cost of half their customers returning the adapter because it doesn’t work with their device.
All two dongles I have used (Google, Apple) have a DAC.
