Sound is available on the computer generally as Windows Media Player has sound. In Elements 12 I added some narrations using the narration window where I deselected the audio mute, but then muted the audio icon on the task bar. Next morning there was no audio and the audio icon was missing from the task barn. This is now back in place after a reboot. Mutes in the Audio Mixer, in Realtech HD Audio Manager and in the taskbar audio icon are not selected. I started a new project and added video/audio tracks to V1 and A1 using both Quick and Expert views but still no sound; please help!
