You may get sound with no battery but I would expect the level to be low and distorted possibly.
Maybe you have wired it up incorrectly (pictures 🙂)

I found it easier to follow this, than the pictures on that site.
An externally hosted image should be here but it was not working when we last tested it.
It's a standard circuit configuration... if taking the battery out makes no difference you have it wired wrong 🙂
Hi, i had the same problem with cmoy .
The problem was the resistor in out r3 o r4 i don't remember, but the problem is an error in the connection
