could u check this ????

Hi all,
I am trying to build a voice record/playback using APR 9301 chip.
I constructed a circuit according to the sample circuit for Push-button mode datasheet except:
- 8 Ohm instead of 16 Ohm speaker.
- I did not have those 1 uF polarized caps
When in playback mode, I only hear some noise like when you hear from the radio. I think it means that the circuit work.
But I couldn't record anything, even if I used LM386 amplifier
I checked my circuit several times and couldnt find any mistake.
Really appreciated if anyone could help
Thanks!

Which circuit did you build?

I can't see any 1µF capacitors.

I've attached the first schematic on the datasheet.

As it's designed to drive a 16R speaker, you shouldn't connect an 8R, you can use a small amplifier such as the LM386 to drive an 8R speaker.
