@Uncle_Leon There are some limitations regarding volume on audio devices for Europe. Check this: Volume operation in compliance with European and Korean Directives For European customers For Korean customers (models supplied with headphones) The alarm (beep) and warning [Check the volume level.] are intended to protect your ears. They occur when you initially turn the volume up to a harmful level. You can cancel the alarm and warning by tapping [OK] on the alert dialog. Note You can turn up the volume after you cancel the alarm and warning. After the initial warning, the alarm and warning will repeat every 20 cumulative hours that the volume is set to a level that is harmful to your ears. When this happens, the volume will turn down automatically. If you turn off the Walkman after you have selected a high volume that may damage your eardrums, the volume level will automatically be lower when you turn on the Walkman the next time. The alarm will not sound when there is an active Bluetooth connection. You can turn this off, search SonyNWDestTool. This will remove the volume limitations and you will notice that similar volume values are higher then before applying this “patch”.
