I just tested. There seems to be no difference. I tried with iec958: and
spdif: instead of plug:iec958:. The problem persists. 

As I said, putting the process in SCHED_FIFO mode doesn't make any
difference at all. Almost any machine activity (any process being active
for more than a fraction of a second) is enough to interrupt the sound.
Does the library use some auxiliary process to play through spdif?
