Hello all I received my UMC404HD two days ago and have been battling with the same problems since then. In Reaper I like to record at 48k/256 and sometimes watch tutorials on YouTube. I tried the steps above and am still unable to play Spotify or YT when reaper is open in 48k mode. Windows/Chrome seems to force 192k and then there's no playback. Rather irritating me as my 2i2 didn't have any of these problems, albeit 2 less inputs. Any ideas?
