I want to keep the internal speakers off, because I have my interface connected via the L and R 6.35mm jacks.
In "Menu" -> "Setting" -> "Speaker" I can turn them off, but when I turn the keyboard off and on, it forgot that setting.
How can I make the keyboard keep the internal speakers off, even after restarts?
Currently I'm working around this issue by putting a small 3.5mm plug into the headphone jack, which disables the internal speakers as well.
