If the end device is a USB DAC, it would get the sample rate information over the USB. If it's an SPDIF connection, then SPDIF conveys the sampling rate. However, when there is a word clock or other clock in the DAC using SPDIF, AES/EBU, or IIS don't have a way for the sample rate to get from the computer to the DAC. One would need some kind of out of band channel or manual setting. One of the big advantages of async USB DACs is that they solve both problems: they put the controlling clock in the DAC where it belongs, and they allow the computer to tell the DAC what speed this clock should run at.
Another alternative is to always upsample in the computer to a fixed sample rate, bypassing this problem. Whether this is satisfactory or not will depend on the available alternatives for sample rates and conversion software. Note: in the minimalist spirit, this implies doing any sample rate conversions prior to starting music playback. It can be done file to file well in advance if sufficient disk storage space exists, or it can be done on-the-fly while loading RAM if the processor is sufficiently fast and/or the user sufficiently patient.
