Audio Output over Remote Desktop

I would like to play audio (using the audioplayer function) via Remote Desktop Connection (from Windows 11 computer into Windows 10 computer).

When I call audiodevinfo, MATLAB R2022b tells me I have no audio output devices.

However, remote audio works fine otherwise for all applications, including the MATLAB beep function. WIndows' sound settings recognize my audio output device as "Remote Audio"

How can I add the Remote Audio output device to be recognized by MATLAB?

Hi Ze Feng,

To the best of my understanding the said “no audio output devices” issue is being faced while using MATLAB desktop on client Windows 10 system accessed through Microsoft Remote Desktop Connection app on the host Windows 11 system.

The issue can be resolved in the following steps-

1. Ensure that you have remote audio input and output drivers installed on your remote machine. If not proceed with step 2 else jump directly to step 3.

2.Open the remote connection desktop app on your host machine and under “local resources” tab do the followings-

Open “remote audio” setting and configure remote audio playback settings as in the below image.

Click the “More” button under “local devices and resources” and check the other supported plug and play devices.

Connect to your Remote machine and verify step 1, Hopefully you must now could see the drivers under audio inputs and outputs. If not refer to the following article on redirecting I/O resources from host to client machines https://learn.microsoft.com/en-us/answers/questions/86750/remote-desktop-connection-not-pulling-in-audio-fro

3.Open MATLAB app and clear toolbox cache, restore path and refresh the list of available audio devices using the following commands.

  rehash toolboxcache;
  restoredefaultpath;
  savepath;
  audiodevreset;
  audiodevinfo

Hopefully the "audiodevinfo" will now have a structure with two non-empty output and input fields.

Hope it helps.
