How to control several speakers with arduino by SD card?

Question

Everyone,I have a question "how to control several speakers with arduino by SD card"

I have used the "TMRpcm" library to make the speaker make a sound already. It's success to make a sound,but, the library only have one output(5,6,11 or 46 on Mega, 9 on Uno, Nano, etc). I want to use several outputs, in other words, it can have allowed many speakers to make sounds at the same time. I don't know how to do that...

looks like it can have a 2nd track with 2nd speaker. See Multi Mode at https://github.com/TMRh20/TMRpcm/wiki/Advanced-Features
