Hi,
is there any way to disable initial tune which is played during startup? It's annoying when you change some configuration and each time device reloads you must hear that sound.

Hello,

This initial tone can't be disabled.
Indeed, when phone play the tone it's doing a voice parameter configuration by receiving the echo of this tone.
Since the phone may be placed into different environment, to ensure best voice quality it plays the tone to finish an automatic configuration.

Regards,
James
