• Switch to the Local Resources tab
• In the Sound section, select Play audio in the following locations and check "On Remote Computer"

Ensure the audio service is running normally

There are several audio-related services in Windows that can also cause remote desktop audio to fail if they are disabled or stopped abnormally.

1. Press Win R to open the run window, enter services.msc to enter to enter
2. Find the following services:
   • Windows Audio
   • Remote Desktop Services
   • Remote Desktop Configuration
3. Make sure that the status of these services is "Running". If not, right-click and select "Start"
4. Also set their startup type to "Auto"

Especially the "Windows Audio" service, once it is disabled, there will be problems with local and remote sounds.

Update or reinstall the audio driver

• Expand "Sound, Video, and Game Controllers"
• Right-click your audio device → select "Update Driver" or "Uninstall Device"
• After uninstalling, restart the computer and let the system automatically reinstall the driver

Check whether the audio output device of the remote computer is correct

Sometimes, although audio redirection is set, the default playback device of the remote computer is wrong, and the sound may not be heard.

• After logging in remotely, right-click the taskbar volume icon
• Click "Sound Settings" or "Open Sound Control Panel"
• Check if there are devices selected as default devices in the Playback tab (usually speakers or headphones)
• If not, try manually switching or plugging and unplugging the device test

In addition, in order to save resources, some remote servers turn off the audio device by default, and administrator permission is required to enable it.
