This should not make any difference, except for radio streams, eventually, but...
Then, I would also try disabling some of the watchdogs, as it seems you need none; after all it is a Pi3...
also, you have the logs to ram, and also /tmp on ram... as your Pi is a 1GB RAM, that could make it struggle, especially "after some time"...
