Nokia E5-00 - Why is the start up tone muted when I insert the SIM and switch power ON on my Nokia E5-00 device?

This issue only occurs when the device is in offline mode (with or without SIM) and is switched off and then switched back on (with SIM). During this start up the user is asked if the device should continue in offline mode. When selecting no the device initiates a profile change from offline to normal mode. During this process the intro sound is muted.

The settings must be: Menu > Crtl.Panel > Settings > General > Personalisation > Tone > Warning tones > ON
