• Issue:

  • By default, DP can be used as an audio output device on eLux 6.

  • Some environments may not require DP audio and prefer to disable it.

• Disabling DP Audio Output:

  1. Open Scout Console and select the target OU.

  2. Navigate to Commands → User Defined command.

  3. Run the command:

      

      

     fs open; echo "blacklist snd_hda_codec_hdmi" >> /etc/modprobe.d/hdmi-blacklist.conf
     

  4. Check Run with system rights and execute.

  5. Enter the device password when prompted.

  6. Restart the device.

  • Result: DP audio output will be disabled.

• Re-Enabling DP Audio Output:

  1. In Scout Console, run the reversal command:

      

      

     fs open; chattr -aA /etc/modprobe.d/hdmi-blacklist.conf; rm -f /etc/modprobe.d/hdmi-blacklist.conf
     

  2. Check Run with system rights and execute.

  3. Restart the device.

  • Result: DP audio functionality will be restored.

• Notes:

  • Disabling works by preventing HDMI audio modules from loading.

  • Re-enabling requires removing the blacklist file.

  • Both actions require a device restart to take effect.

On eLux 6 devices, DisplayPort (DP) audio output can be disabled if not required. This is achieved by blacklisting the HDMI audio module via a custom command in Scout Console. The process can be reversed by removing the blacklist file, restoring DP audio functionality. Both actions require a device restart.
