Start a Skype call, and it makes it's ring sound, then you can hear a conversation, and system sound icon in the menu bar shows volume increased (without manually adjusting anything!).Įnd the Skype call, and volume (system volume!!!) automatically returns back to 'muted'.Īs far as I understand, it cannot be changed by any setting in Skype (and confirmed by Skype support chat, it's just how Skype works, and they think it's correct), sound output is 'same as system', notification sounds are disabled, and there are no other settings. In reality - system sound is 'muted', volume icon in the menu bar indicate that. I could be wrong but I believe that's what everybody's understanding of 'system volume' should be. Something like what a mechanical volume control knob would do. So, if 'system volume', is muted, no app should be able to make any sound.
My understanding of 'system volume control' - app may adjust it's sound output but after it leaves the app, it still passes through the 'global' or 'system' volume control. I thought I explained it very very clearly but I will try again.
