Snaps, crackles, pops and drop outs - for information

This is useful information. Thanks for posting.

To flesh out some details that could be useful to others,

• there are three different versions of the RPi3---A+, B, B+. Which were you using?
  

• since you have a DAC hat, I assume you are using Bluetooth for input and not output, yes?
  

• were you also using the built-in WiFi as your network interface, and if so, at 2.4GHz or 5GHz?
  

The reason for the last question is, Bluetooth shares the 2.4GHz ISM band so there is the possibility of mutual interference.
