No Sound or Wrong Volume on a Display | easyCMS Digital Signage

A screen plays video with no sound, or far too loudly: volume is set in three places, and only one of them is inside easyCMS.

Where	What you can set
The screen	Volume, mute, and where it sends the sound.
The player device	The Android box or PC’s volume and mute. easyCMS cannot read or change them.
The layout, in the advanced editor	A video widget is muted (Mute videos that have audio) or plays at the device’s volume. An audio item has a Volume percentage and Loop. Studio has no sound setting.

Good to know The quietest link wins: a widget at full volume is still silent on a muted panel. easyCMS has no master volume, so start at the screen.

Which problem you have

Symptom	Likely cause	Fix
Nothing has sound	Panel or device muted	1 to 3
One video is silent	No audio track, or a codec the device cannot decode	4
Picture arrives, sound does not	Sound sent somewhere else	5
Sounds mix into noise	Several items playing sound	6
Too loud in the evening	easyCMS has no volume schedule	7

Fixes, quickest first

Unmute the panel with its remote and raise its volume. A screen muted at installation stays muted.
Check the device volume. On Android, press the volume keys while something with sound plays, so you change media and not notifications. On Windows, check the master and the player’s own level in the volume mixer; levels set under another Windows account may not apply.
Play something else on the device, in its own browser or media app. Silent too? The hardware is at fault, not easyCMS.
Check the file in a desktop media player for an audio stream: many “export for web” presets drop it. AC-3, E-AC-3 or DTS audio may not decode on signage hardware. Re-encode to MP4, H.264, AAC 128 kbps stereo: see Videos Will Not Play or Stutter.
Follow the HDMI. Windows sends sound to its default output, which may not be the screen (Windows Player Setup). An Android box may switch to its 3.5 mm jack when anything is plugged in, even a dead cable. Panels are often set to a soundbar, ARC, line or optical output. Cheap HDMI switches, splitters and extenders drop audio: test with one short cable straight to the screen.
Let one item speak. In the advanced editor, mute every video widget except the one to be heard, including those in your default layout. Attached audio plays only while its parent widget is on screen.
Build quiet hours into the content. Make two versions of the layout, one muted or with a lower Volume, and schedule each against a daypart: see Scheduling Content and Timezones, Dayparting and Schedule Accuracy. Some panels and Android sticks accept mute commands from easyCMS, depending on the model, once we set them up.

On LG webOS the panel’s own volume and mute are the whole story: easyCMS can push backlight, brightness, contrast and remote locks, not volume. If staff keep changing the sound, ask us to lock the remote. Where sound matters, an Android or Windows player gives more control.
