Audio output is distorted on device speaker. No audio output thru audio interface

[Mike Hunt Too]

Switched some settings in AE. Increased buffer size to max. Created a new project, so that the sample rate matched the audio interface setting.Plays good on device.
Connected audio interface , had a momentary
Display output set to Android, and would I like to change it to USB.
Selected yes and now project plays
Thru audio interface.
