USB audio is always isochronous, that is what the standard says.
Next question is how the synchronization is taken care of.
In adaptive mode, the DAC indeed adepts its own clock speed to keep pace with the incoming data stream.
In case of isochronous USB with asynchronous synchronization, the reverse happens. The clock of the DAC runs at a fixed pace and the buffer management is done by the USB receiver of the DAC.
It simply tells the PC the send more or less data to prevent buffer over- or onder-run.
