Decrease the temperature.
Reason: in a solid the sound speed v ≈ sqrt(Young’s modulus / density). Lowering temperature generally raises the material’s stiffness (Young’s modulus) and so increases v. Switching to a gas or liquid would slow the wave (sound travels fastest in solids), and increasing temperature usually lowers the speed in metals.
