NE5532A: Single supply voltage

Part Number: NE5532A
I tried to supply +15V and use it as a non-inverting amplifier.
But it didn't work well.
It worked well with ±15V.

Accordng to the data sheet, it can be operated as a single supply.(8.4 Device Functional Modes)
Do you know why it doesn't work with a single supply?
