May I know how to set the switching frequency for the TAS5756M? By Hardware or by setting register?
I try to put 6.3V, 3.5V, 2.8V, 2.3V, 2.0V on SPK_GAIN/FREQ pin of TAS5756 and also try change register P0-R34 Switching frequency speed Mode[1:0] to 00, 01. or 10.
But the output signal(SPK_OUTA+ to GND) frequency is still keep on the same on around 141kHz ( Mono(PBTL) system application )
