Audio — HDMI and DisplayPort

TranslationTo pending.enable HDMI/DisplayPort audio, first, follow the instructions in the "Configuring Audio Devices" guide. If the issue persists, it's likely caused by a Pulseaudio bug. Next, consult "HDMI Output Configuration."

For the openthinclient model 1688, this means specifically:

    Connect the monitor that will output audio via the lower DisplayPort (DP-2/DP2).

    Create a command-line application, set it to autostart, and copy the following command:

    sudo sed -i 's/^load-module module-suspend-on-idle/#load-module module-suspend-on-idle/; 
s/#load-module module-alsa-sink/load-module module-alsa-sink device=hw:0,7/' 
/etc/pulse/default.pa; systemctl --user restart pulseaudio

    This command enables audio via the DP-2 port hw:0,7 It routes audio exclusively through the DP-2 port, configures the built-in speakers to remain silent, and restarts the audio service.

    To use HDMI/DisplayPort audio on other thin client hardware, follow the external instructions to identify the correct hardware name, e.g. hw:0,3, hw:1,4, and adjust the command accordingly.
