There is a known issue with ONE (the original ONE, not the ONE for iPad & Mac) where the input will switch back to ”Internal Mic” after unplugging/replugging the ONE, restarting the computer, or doing a sleep/wake.

If you have the input set for ”Ext Mic”, ”Ext Mic 48v”, or ”Instrument”, the following will happen after unplugging/replugging the ONE, restarting the computer, or doing a sleep/wake:

– The input label in any CoreAudio applications, such as your recording software, System Preferences Sound, or Audio MIDI Setup will switch to ”Internal Mic”.

– The input label in Apogee Maestro will switch to ”Internal Mic”, even though it will still show the input source that you had selected.

– The input encoder in Apogee Maestro will reflect the gain range of the ”Internal Mic”, so it will graphically show that the input level is raised, but you’re not able to lower it.

 

This is a known issue with ONE and it will be fixed in a future update. Until then, the workaround is to toggle the ”Analog Level” in Apogee Maestro to ”Internal Mic” and then back to whatever input source you were trying to use.
