No sound playback - What to do?

It can happen that you have started TightGate-Viewer, started a video or a radio stream and there is no sound playback on the Windows PC. The following checklist provides information on what to check in this case.

1. Is local sound playback possible on the Windows PC?
   Please play a local audio file on the Windows PC and make sure that local sound output is possible. If this is the case, please check the next step
2. Is sound playback activated on TightGate-Pro?
   Please check that global sound playback is activated on TightGate-Pro. To do this, please as administrator config on TightGate-Pro and make sure that under System defaults > Audio support = Yes is set to Yes.
3. Does the user ID have authorisation to use sound?
   For user administration via Active Directory, check that the ID is a member of the AD security group tgaudio security group.
   In all other cases, the administrator maint check whether under the menu item User administration > Change user > [User ID] > Audio on Yes is set to Yes.
4. Does the TightGate-Viewer allow sound playback?
   Please start TightGate-Viewer and open the settings menu in TightGate-Viewer using the function key F8. There please select the menu item Settings and select the tab Sound tab. Please make sure that the option TightGate-Pro-Switch on audio is activated.
5. Is the sound from TightGate-Pro connecting correctly?
   It is now necessary to check whether the sound from TightGate-Pro is being transferred correctly to the Pulseaudio on the Windows PC. To do this, please open a command prompt (CMD) on the Windows PC and in the user session with which the TightGate-Viewer is used. Please enter the following command in the CMD without starting TightGate-Viewer:
   

    netstat -ano | find "4713" 

   
   
   Nothing should be displayed as output, which means that there are no active connections on the Windows PC to port 4713. Port 4713 is used by default by Pulseaudio to play sound from TightGate-Pro.
   Now start TightGate-Viewer and do not yet have any sound actively playing. Repeat the following command in the CMD.
   
   
   
   The output should now show that Windows is listening on port 4713 (LISTENING).
   Now start an audio output in TightGate-Viewer (e.g. a YouTube video) and then execute the command again in the CMD.
   
   
   
   The output should show that a connection has been established and the sound should be played back.
