Sleep mode problem

[PapyOurs]

Hi,
 I have a small problem... After having a problem with the "dir buffer is full" even after increasing max files (it wasn't saving the changes) I reinstalled everything and it is now working fine.

After reinstalling the whole system, it doesn't go in sleep mode when earphones are plugged of... The first time I installed rockbox it was doing it automatically but not anymore... I have set the timer on 10min but still nothing after one hour...

Any idea what I've done wrong?

Is "pause on headphone unplug" enabled? If not it will simply continue playing, and that will make the idle poweroff not kick in (since it's not idle )
