No Audio Passthrough on RK3588 Board

[wenjucktes01]

Hello together,
I have an OrangePI5 Plus so an RK3588 Processor. My Issue, the Audio passthrough doesn´t work. Windows itself says it has now Audio Device conected. In Linux i have an Headset conected via AUX. If sb has a fix or clue why the issue occurs, i would be really apreciated. If more information is require fell free to ask.

I will assume you are using the connect mode, not direct. Connect will use a RDP client which handles sound.
I don't have complete control over the RDP client, and only can change the settings it gives control over. Specifically, for the Remmina client, it has its own config file that allows for audio to be enabled, which I have made the default.

Both RDP clients seem to output to whatever your system's chosen audio output device is, so make sure that is selected correctly.

If that does not work, you can try changing the config file to use a specific ALSA/pulseaudio/pipewire audio output device of your choice. For remmina, this is done with the audio-output line in the file. See the documentation here: https://remmina.gitlab.io/remminadoc.gitlab.io/md__builds__remmina_remmina_ci__remmina_wiki__remmina__config__file__options.html

Be aware that I have not tried this, and would have no way of knowing the exact value to use in your case, as it varies by the hardware. Use a search engine or AI tool if you get stuck. Hope this helps.
