help with pop in channel switching and boost

[emartine]

Well, I can confirm that pop comes from the PI side, since I disconnect the two leads that go from Dpdt to PI and no longer I get the pop. I asume I just need to in crease the 1M and 2.2M resistors.. Right? May be to 6.9M?

Good you were able to isolate the source. My earlier suggestion was 4.7M but try 6.9M if you have that on hand. It should work fine.
