I'm using a PCM5102A DAC in a project and I've noticed that when the IC goes to sleep (>1 second without data on the I2S bus) there is some errant switching noise audible via the amp.
If I connect the R/L channels to analog ground, everything sounds great. My question is:
How can I automatically ground the R/L channels when there is nothing coming from the analog output of the DAC?
A monostable has been suggested to me, but I feel like that might be too complex of a solution for this.
