LM386 opamp Module, measuring amplified output without giving it input

Hi. I am using an LM386 opamp Module from Amazon. I am powering it with a 5V input (just to power it, not intending to amplify anything at this point). Nevertheless a multimeter measures an amplified output of around 1v-2v.

When I put an actual input that I want to amplify nothing really changes. Why I am getting an output without giving input?

Thanks all, after connecting a speaker to it I was actually able to confirm that it was working. Further I was also able to measure the voltage change.
