util-linux (which is just installing the full version of taskset) has no bearing on cpu isolation. The kernel decides where it runs kernel code, if the kernel code says to run a process on CPU3, then it will do it, irregardless of the isolation request. In the past, the rpi kernel forced all interrupts to run on cpu 0, but that could have changed. As for squeezelite, there are 4 different processes associated with squeezelite. Are you looking at them individually? piCorePlayer a small player for the Raspberry Pi in RAM.
