[ 1559][E][esp32-hal-cpu.c:110] addApbChangeCallback(): duplicate func=0x400d27d8 arg=0x3ffbdb6c E (1544) timer_group: timer_isr_callback_add(236): register interrupt service failed

Add check for NULL

 if(sTalkieSampleRateTimer == NULL) {
        sTalkieSampleRateTimer = timerBegin(1, APB_FREQUENCY_DIVIDER, true);
        timerAttachInterrupt(sTalkieSampleRateTimer, timerInterrupt, true);
        timerAlarmWrite(sTalkieSampleRateTimer, (getApbFrequency() / APB_FREQUENCY_DIVIDER) / SAMPLE_RATE, true);
    }
