As man page says: "If successful, the sched_setparam() function shall return zero." So the if must be without !
Without update I got this output in the syslog (journalctl): abr 16 09:25:30 mypc alsactl[1652]: alsactl 1.2.2 daemon started abr 16 09:25:30 mypc alsactl[1652]: /usr/bin/alsactl: do_nice:165sched_setparam failed: No such file or directory
That I think that is a wrong message. The call to sched_setparam is correct.
This is the output with strace: getpriority(PRIO_PROCESS, 0) = 20 setpriority(PRIO_PROCESS, 0, 19) = 0 getpriority(PRIO_PROCESS, 0) = 1 sched_getparam(0, [0]) = 0 sched_setscheduler(0, SCHED_IDLE, [0]) = 0 write(2, "/usr/bin/alsactl: do_nice:165: ", 31/usr/bin/alsactl: do_nice:165: ) = 31 write(2, "sched_setparam failed: No such f"..., 48sched_setparam failed: No such file or directory) = 48 write(2, "\n", 1) = 1
Call to sched_setscheduler returns 0, so it means that the call was successful.
