Previously, the iec958 channels status sampling freq was set only if not

to the runtime rate for each PCM session.

substream player private data is used in uni_player_irq_handler to lock,
stop & unlock the stream when interrupt indicates underflow/overflow.
If not set, then segmentation fault occurs.
