Troubleshooting Low ATC Audio Levels Post-Upgrade in MSFS 2020

I gather from your post that you're encountering a diminution in the audibility of Air Traffic Control (ATC) communications subsequent to an update, despite the audio output being maximized. This is indeed a conundrum, but fret not; there are multiple avenues we can explore to rectify this issue.

First and foremost, let's address the in-simulation settings. Within the sound options of Microsoft Flight Simulator, you have the ability to adjust various audio sliders that control different elements like engine sounds, environmental effects, and crucially, the radio communications. Here's a step-by-step guide to ensure these are set correctly:

1. Access the 'Options' menu from the main interface of the sim.
2. Navigate to the 'Sound' tab.
3. Locate the slider labeled 'Communications' or similar.
4. Adjust this slider to the right to amplify the volume of ATC interactions.
5. Ensure other sliders are not at maximum to prevent them from overpowering the ATC.

If these adjustments do not yield success, we may need to delve deeper. Some updates can alter the configuration files of the simulator, leading to unexpected changes in audio output. You can check the integrity of the game files if you're using a platform like Steam or reset the game's settings to default if the simulator provides that option.

Moreover, the issue might not reside within the simulator itself, but rather in the audio configurations of your operating system or hardware. Examine the following:

• Confirm that the default communication device is set correctly in your operating system's sound settings.
• Inspect the mixer settings to ensure that the simulator's audio is not being directed to a different output or being dampened.
• Review any dedicated audio software provided by your sound card or motherboard manufacturer that might be overriding individual application volumes.

In some instances, third-party applications designed to manage audio within the sim, such as voice communication mods or ATC client software, might be a factor. If you have such applications, ensure they are updated and configured correctly to work with the current version of the simulation platform.

Lastly, it could be beneficial to inquire within the community if others are experiencing similar issues post-update, as this could indicate a more widespread problem that may require a patch or a fix from the developers.

If further clarification is needed or if these suggestions do not resolve the predicament, please provide additional details on the specific update and any other changes made to your system coinciding with this issue. I'm here to assist and will await your update to continue our troubleshooting journey.

Remember, the simulation community thrives on collective wisdom, and together we can ensure that your virtual skies are clear and your communication with virtual ATC is crystal clear.

Fly high and clear skies!
