Alarm sound when logging a track with device in pocket

[mamsel2000]

I am using Oruxmaps on a Defy for several years now and I am really happy with it. Recently I bought a Sony Experia Z3 compact with Kitkat 4.4. and installed Oruxmaps. Everything is working well so far but there is one thing that really nerves me:



If a log a track, shut off the display and cover the proximity sensor (put the device into a pocket or cover the display with my hand) I will hear an alarm sound. As soon as I switch the display on or discover the proximity sensor the alarm has gone. This is no wpt nor a route alarm. As far as I can see there are no other alarms enabled.



I do not know what it is but I would like to disable it. Can someone help me please with this,



Thanks,

T.
