-* Attach headphones to the headphone jack using `sounddev=sndpwm` in `config.txt`
-* Alternatively, attach a  PCM5102A or PCM5122 based DAC and select i2c sound output using `sounddev=sndi2s | sndhdmi` in `config.txt`
-* Alternatively, attach a HDMI display with sound and select HDMI sound output using `sounddev=sndhdmi` in `config.txt` (this may introduce slight latency)
