This is 100% up to the operating system and player. No DAC can 'magically' sense the input of a file, it simply takes in the PCM/wave of the incoming datastream, Windows DirectSound will automatically REsample to the device settings standard rate, while WASAPI or ASIO event driven players will always send the original rate. After which the DAC will oversample (often to MHz rates, I think AKM goes to x256 original rate).2. Correctly identify the input frequency of the file and adjust itself accordingly without foobar or any other adjustments in Windows
Software VS hardware. Upsampling VS oversampling... I don't think you have it quite figured out yet.
UAC1 vs UAC2 is another argument altogether. To me it makes sense devices do not stick to old age standards. You can always get something explicitly supporting old UAC1 (like a Fiio E10K, or JDS labs devices with UAC1 firmware flashed). Just need to do your research prior to purchase.
