The Prowise Classic Line has lost all sound, what can I do about this?

Check the following settings in the Prowise menu:


1. Port
2. Audio
3. Visual
4. Display
5. Settings

Is the volume set at a value higher than '0'?

Is there a physical connection with earphones on the Prowise ProLine?


- If so, the audio is muted since it is playing through the earphones.
- In the settings/audio/output menu, select internal (only audio output via the touchscreen) or both (audio output through earphones and the touchscreen)
- Or remove the earphones (2) so the sound is no longer muted.

Check whether the output is set to External.
- If so, the speakers are muted because the sound is set to play though an external speaker.
- Select 'internal' or 'both' to activate the speakers on the Prowise Classic Line. 

Check whether the Mute feature is activated.
- If so, the speakers will be muted.
- Disable the mute feature to let the sound play through the speakers of the Prowise Classic Line.

In case the internal PC module is used as source, check:
- The Windows volume settings
- Device that is playing (in the Window audio settings)
          PC monitor 2 Intel Display Audio
- Audio drivers.
          Update the Audio drivers for the PC monitor 2 Intel Display Audio device in the Windows device manager.

In case an external PC is used as source, check:
- The external cabling of the external PC to the Prowise Classic Line.
- Whether the Windows volume settings are correct.
