TMRpcm Wav audio value read?

so i got the lib and wav files playing right with no issues...

but my question that i cant see to find is how can i do a serial print on the followings below to get their value...?




i have tryed doing "Serial.print(tmrpcm.volume());" but nothing was working ... am i doing something wrong here?

I don't believe any of those functions return values. They simply set the volume, quality and loop based on what you specify. I don't think there's a way to query the current status of those functions. But, I'm not a ninja coder so I could be wrong.
