Should I expect this to work with using PWM for playing audio?
Thank you.

Here is a link to the schematic for the Amplifier module:

I should have been more clear.
I am referring to the DFR0064, 386AMP audio amplifier Module (Arduino compatible).
Do you have a schematic for this? I'm using a PWM audio input to this device but I'm not getting any amplification. The audio from the speaker is the same as using a simple resistor between PWM and speaker itself. I must be doing something wrong and a schematic might help me troubleshoot.
Thanks,

We do not have an "audio shield" but we do have a few different shields that play MP3s or amplify audio. I am not sure which product you are talking about.
If you are talking about the DFRduino player.
Please have a look at the product page. At the bottom there is a link to the schematic.
