+Subject: [PATCH] alsactl: fix error handling for sched_setscheduler() call
+MIME-Version: 1.0
+Content-Type: text/plain; charset=utf-8
+Content-Transfer-Encoding: 8bit
+
+As man page says: "If successful, the sched_setparam() function shall return zero."
+
+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
+
+If sched_setscheduler() returns 0, so it means that the call was successful.
