One possibility is to resample everything to a specific sample rate so the DAC never has to change rate. This can be done in the server if it is running on a powerful enough computer. Are there any sample rates that play back correctly? To do the conversion you need to make a custom-convert.conf for the server and set the parameters right. This depends on what your file types are and whether you like to stream flac or pcm etc. I don't have a pi so I can't help with that, but clicks and pops etc can frequently be resolved with proper settings on the computer (pi in this case), but I'm going to have to defer to the pi experts on that. Things like other programs running on the machine, exact OS being used, whether streaming flac or PCM, buffer settings etc can all make a difference.
