I am:
1) connecting the DAC output to low impedance ear bud speakers
2) looping the DAC outputs to the ADC inputs
When I switch (in real-time) between the HP_MODE line out and headphone out settings, I do not see any change in signal level neither case 1 nor case 2 above.
Other than the PB1_EN, PB0_EN, are there any other bits to make this setting functional?
Can I modify the setting in real-time?
I know the I2C interface is working in that my init works and my switch logic works for DAC mute (in real time).
How can I test whether this feature is working?
Thanks,
Dan
