Google Pixel as endpoint

I am new to Roon. I have noticed that when I select my Google Pixel smart phone as my audio device, and listen through it, I get a lot of clicks and pops. This doesn’t happen when I listen through any other audio app on the phone (Tidal, GooglePlay Music, or Jriver/Jremote). Has anyone else experienced this? Anyone know how to remedy the problem?

Anyone have any ideas?
