Can the internal speakers be turned off in the 910 without disabling the line out as well?
Have you tried just plugging in a headphone in or just a jack in. Then the audio to the speakers goes to the headphone. Line out should not be affected - anyone tried that on a psr910?

In the manual it says...."Connect a pair of headphones to the [PHONES] jack. The internal stereo speaker
system is automatically shut off when a pair of headphones is plugged into the
[PHONES] jack."
