SX-900 Speaker Issue

[hammer]

Yesterday at a gig I could not get the on-board speakers to put produce much sound.
I had my Bose S1-Pro speaker plugged into the keyboard and the on-board speaker setting set to "ON" but the sound level coming from the speakers was so low I could hardly hear them.  I have used the on-board speakers set to "ON" while using my Bose S1-Pro speaker many times and the on-board speakers worked great.  I have checked all the setting I can think of but have not found anything that might have changed to cause this.  Any ideas?

Do you have anything plugged into a foot switch port?  Perhaps it got accidentally changed to volume?
I can't think of anything else Deane, but you might try a factory reset.

Suggest you check the EQ & CMP are as they should be.

Did a factory reset and now back to normal.

Thanks,
