Hello, OS: Windows 10 64bit v2004 Notes: 10.0.1 FP6 Basic Configuration Using Notes for gmail POP mail - when new mail arrives (local database replication) there is no sound notification. Setting: [CODE]File->Preferences->User Preferences...->Mail->General->Receiving->Play a sound[/CODE] is checked. Notes/OS sound config is also Ok - if I select custom sound using Browse button: [CODE]File->Preferences->User Preferences...->Mail->General->Receiving->Play a sound->Browse...[/CODE] Notes plays sample audio just fine. Any ideas ? Thanks, Vilius M.
