Fix: Discord Not Working with Audio Interface [2021]

Written By FarhanMax

Imagine the frustration you would feel if you could not join your friends in a voice chat only because Discord cannot access your mic no matter how you try!

As Discord is my primary communication platform, I can relate your situation with me. I often faced this inconvenience and spent hours trying to find the reasons behind it.

Finally, I was able to point out the possible issues and their solutions.


So, why is Discord not working with the audio interface?

Discord won’t pick up your microphone if it doesn’t have permission to access it. Also, if you don’t select a specific input device in Discord settings or the input device driver isn’t updated to pair with Discord, you cannot use it in a voice chat.

Don’t worry; just forget this technical gibberish and follow my instructions throughout the post to find and resolve Discord not working with the audio interface.

Why is my Discord not picking up my mic?

Discord needs microphone access to hook you up in a voice chat. But if it doesn’t have the microphone access permission, there is an interruption like faulty audio port, overlapping mic access, and the backdated audio driver. Any of it can block Discord from picking up your mic.

Discord is a communication platform, and for this purpose, it needs to access your input devices when you make a voice call or join a voice chat.

Discord runs various processes in the background to ensure you a flawless voice call. It is dependent on several components of your PC. Input device like the microphone is one of them.

To access and use your input devices, Discord has to go through various steps, and if everything is up to the mark, it can only make use of that component.

So, let’s discuss these background processes that might mess up your input device’s settings for the Discord app.

Here are the reasons that could result in the Discord app not working with the audio interface:

Residual Discord Cache Files

You probably noticed that Discord creates small temporary files to complete small background tasks like taking notes in class.

Although these cache files are critical for running Discord properly, sometimes they pile up as junk files after their respective processes are finished. They then conflict with newer cache files and interrupt new Discord processes.

Audio interface problems can arise from these conflicting files until they are appropriately cleaned. They’ll occupy microphone access until they are cleaned to accommodate new cache files.

Concurrent Input Device Access

If you’re running two softwares with input device access simultaneously, you’ll face the Discord audio interface problem.

Additional components of your pc like webcam and microphone can only accommodate one software access at a time. Running two of them concurrently will block access to one of them.

Communication softwares like Discord, WhatsApp, and Messenger requires continuous access to input devices. If you run them alongside, you’ll face audio interface issues like the one we’re discussing.

Backdated Audio Driver

Your audio interface won’t work properly and will give you a hard time if you haven’t updated them in a while.

Every component of your pc requires their respective drivers to function when needed. Drivers are the connection between your device’s CPU and the components. Without proper drivers installed, the components will malfunction, like an audio interface not working.

You need to check for updated drivers for your input devices and install them properly to avoid audio interface problems.

Faulty Audio Port Accessories

Sometimes, Discord’s not working with the audio interface is simply a faulty headphone or a loose audio port.

As a constant headphone user, I can assure you that if you plug and unplug your headphones like there’s no tomorrow, then it’ll wear off after a few days, and you’ll be left with a loose headphone port to work with.

You’ll face a continuous struggle to connect your headphone properly with your pc, and with a slight movement, they can disconnect from your pc.

Inappropriate Discord Settings

In the Discord app, there are several settings options to personalize your input device and microphone preferences.

You can customize them as your necessity. But, enabling the wrong option could result in malfunctioning input devices. Before setting up your audio devices and input methods, try to understand their consequences and requirements.

Inability to Run Discord’s Process

I mentioned that running two communication apps concurrently can conflict with microphone access and malfunction. Also, when Discord’s background process conflicts with any other app, it’ll malfunction, and some processes will be terminated, like microphone usage.

If you run the Discord app properly in the first place, you can avoid facing this type of problem, which I’ll show you later.

Outdated Discord App

An outdated Discord app will malfunction and arise various issues like audio interface inaccessibility, RTC connecting issue, etc.

Outdated Discord app cannot cope with the latest offerings from Discord admins, and you cannot experience the full potential.
