I'm running picoreplayer on a raspi3 with an amp+.
LMS, squeezelite and shairport are running. I am predominantly streaming spotify using the spotty app. Do a bit of straight airplay too.
After about 15 mins of playing some random clicking develops. At first I thought it was because it was linked and synced to another pi on the network. After shutting that off the problem continued.
I thought also maybe it had something to do with the fact that picoreplayer was running shairport and at the same time lms was running shairtunes2. But Ive experimented with running each of them by themselves and that hasn't fixed it either.
Not sure what else to try
