My current Yulong U100 USB DAC supports up to 24/96. However, for some reason it cannot play 24/88.2 files on foobar2000 WASAPI. My question is would it be better to upsample to 96khz or downsample to 44.1khz before sending the signal to the DAC? I know it's usually best to resample in integer values.
Also, is it common for a DAC to support 24/96 but not 24/88.2? In other words, is it possible for me to tweak the configuration so that it can play 88.2?
