I've connected 150ohm small speaker to GP2 and GND pin of pico with 2k2 resistor on GP2 and 2200uF capacitor connected to GP2 TO GND.

You have to connect the speaker and the capacitor in series between GP2 and GND. Then you may hear some very faint sound. If I see that sample video right, the RP2 was connected to an active speaker with built-in Amplifier. That is the best approach to take.
