Just some clarification as to the nature, Oom is based on MusE so the
same error can occur for us (with MusE that is).
I can see that the error message can be improved after reading Ralfs
reply, usually the reason is due to device file permissions, didn't
know it could actually be because of a value limitation. I'll give it
a look for improvements.

Also, having rtc timing is as someone noted not a strict requirement,
as it will fall back on the system timer, though on many systems this
is set too low.

Regards,
Robert
