Verify your speaker wires are correct and the volume is adequate.

my volume is 30 and my speakers are supportable by the DFplayer mini (speaker: 1W 4ohm)
Show your wiring diagram.

check your speaker with multi meter
by connecting +ve & -ve
if sound coming through multi meter, check wiring or code
if not, replace speaker
No. Sound for the speaker will not come through the multimeter. At most, the speaker will give a "click" sound from the diaphragm as the weak voltage from the multimeter briefly charges, then discharges the speaker coil.
No. If the weak voltage from the multimeter was insufficient to cause a "click" in the diaphragm, that is not reason to discard the speaker.
Also, try the "I/O mode" of the DFPlayerMini, here... it only requires SPKR+, SPKR-, VCC, GND and a shorting jumper.
Without your full code and wiring connections it's guesswork. So if you're still seeking help...
