PWM Audio with the MSP430 - MSP low-power microcontroller ...
https://e2e.ti.com/support/microcontrollers/msp-low-power-microcontrollers-group/msp430/f/msp-low-power-microcontroller-forum/254519/pwm-audio-with-the-msp430
I have an audio amp and it doesn't seem like the noise is coming from there. If I connect a speaker directly to the 430 (I'm using the EXP430F5529 board) I still hear static. I'm running this single ended, any thoughts as to filtering? Would this help reduce static or is this just something you live with for PWM audio?
Low-Cost Speech With MSP430™ MCUs - TI

Low-Cost Speech With MSP430™ MCUs 3.2 Audio Playback With PWM PWM is often used as low-cost solution for a digital-to-analog conversion. Analog audio also can be generated by PWM, and Figure 2 shows the signal flow for a PWM output with audio data stored in internal flash memory. For more information about audio playback using a PWM DAC, see ...

https://circuitdigest.com/microcontroller-projects/msp430-pwm-tutorial-led-brightness-control/
Upload the code to the MSP430G2 board and turn the potentiometer knob. As you turn the knob the voltage on pin 2 will vary which will be read by the microcontroller and according to the voltage the PWM signals will be generated on pin 4. The greater the voltage, the greater will be the duty cycle and vice versa.
