Just received my Modi 2 multi-bit and have been experiencing the same types of problems. Oddly enough Windows 10 reconizes my DAC and appears to playback just fine even at 24/192 which is odd considering I thought it was limited to 24/96 without the schiit drivers. Did Windows update to now support both USB 1 and 2 class audio and I didn't even realize it? Lastly sorry if a tad off topic but what is the best tool to check a DAC capability and print out the results using windows? Does such a thing exist?
