Run the sketch and open up your Arduino Serial console. If there's a problem you'll get a failure to set the volume
initially
If it's OK, you can send multiple +'s and -'s to increase or decrease the volume. The volume can go down to 0 or up to
63 (which is 29dB of gain)
return;
if (thevol > 63) thevol = 63;
if (thevol < 0) thevol = 0;
setvolume(thevol);
}
