There is no reason the DAC or ADC can't internally do the resampling itself. In fact, most take it to the extreme - they resample to several MHz, but at 1 bit per sample, with noise shaped dithering as explained in the video linked elsewhere. They then have a very simple analog low pass filter - the noise is shaped far into the stop band of the filter. That is no reason to store or even process your music at higher rates, though.

> There is no reason the DAC or ADC can't internally do the resampling itself. You are describing alternative (b) i mentioned above: digital filtering plus oversampling. This also isn't without side effects. Oversampling a 44KHz signal is not the same as having a 192Khz material to start with. Very different.

  Yes, and the only difference is the lack of unwanted ultrasonic signals.

    No, it is not, please do take a deep look at oversampling in D/A conversion and the artifacts of digital filtering, articles are out there.
