Windows 11 Stops Detecting HDMI AV Receiver Sound Device (Sony STR-DN1030)

Windows 11 Stops Detecting HDMI AV Receiver Sound Device (Sony STR-DN1030)

If you're using a Windows 11 PC and have an AV receiver (Sony STR-DN1030) connected via an HDMI port on a Nvidia display adapter, you might have encountered an issue where the sound output device stops being detected. This article will cover the key concepts related to this problem and provide a detailed context to help you troubleshoot and resolve the issue.

1. Checking the Connections

The first step is to ensure that all the connections are secure. Make sure that the HDMI cable is properly connected to both the PC and the AV receiver. Also, check that the Nvidia display adapter is properly seated in the PCIe slot.

// Pseudo code
if (connection_status == "Disconnected") {
  connect_HDMI_cable();
  secure_Nvidia_display_adapter();
}

2. Updating the Audio and Display Drivers

Outdated audio and display drivers can cause compatibility issues and prevent the system from detecting the HDMI AV receiver sound device. To resolve this, you should update the audio and display drivers to the latest version.

// Pseudo code
update_audio_driver();
update_display_driver();

3. Changing the Default Sound Device

Sometimes, the system might not automatically detect the HDMI AV receiver as the default sound device. In this case, you can manually change the default sound device in the Windows 11 settings:

1. Press the Windows key + I to open the Settings app.
2. Click on "System" and then "Sound" from the left-hand menu.
3. Under "Output," select the HDMI AV receiver as the default sound device.

// Pseudo code
settings = open_settings();
settings.system.sound.output = "HDMI AV Receiver";

4. Checking the Power Management Settings

The power management settings for the Nvidia display adapter can also affect the system's ability to detect the HDMI AV receiver sound device. To check the power management settings:

1. Press the Windows key + X and select "Device Manager" from the menu.
2. Expand the "Display adapters" section and right-click on the Nvidia display adapter.
3. Select "Properties" and then click on the "Power Management" tab.
4. Uncheck the "Allow the computer to turn off this device to save power" option.

// Pseudo code
device_manager = open_device_manager();
nvidia_display_adapter = device_manager.display_adapters.nvidia;
nvidia_display_adapter.power_management.allow_computer_to_turn_off = false;

5. Performing a System Restore

If none of the above solutions work, you can try performing a system restore to a point where the HDMI AV receiver sound device was still being detected. To perform a system restore:

1. Press the Windows key + S and type "Create a restore point" in the search bar.
2. Click on the "Create a restore point" result and then click on the "System Restore" button.
3. Follow the on-screen instructions to choose a restore point and complete the process.

// Pseudo code
system_restore = open_system_restore();
system_restore.restore_to_point("HDMI AV Receiver Detected");

• Check the connections and ensure that the HDMI cable and Nvidia display adapter are properly seated.
• Update the audio and display drivers to the latest version.
• Change the default sound device in the Windows 11 settings.
• Check the power management settings for the Nvidia display adapter.
• Perform a system restore to a point where the HDMI AV receiver sound device was still being detected.
