Once my microphone is picked up, whether that be on discord or in game, it massively distorts the audio of my games. I thought it could be just my headset but i used a different headset and it does the same thing. The confusing part is that itll intermittently do it, sometimes it will act as it should, others it does what im describing.

    Hello Justin Allen,

    This issue may be caused by Windows changing the audio behavior for communications, an application taking exclusive control of the headset, or a conflict with Discord’s voice settings. Please try the following:

    Press Windows + R, enter mmsys.cpl and select the Communications tab > Choose Do nothing > then click Apply. Next, under Playback, open your active headset’s Properties > Advanced and clear both Exclusive Mode options.

    For Discord, go to User Settings > Voice & Video, scroll to Audio Subsystem, and switch between Standard and Legacy. Also temporarily turn off Enable Quality of Service High Packet Priority, then test again.

    Please let me know how it goes after trying these steps, and I'll be glad to continue looking into it with you.

    If both headsets connect by Bluetooth, configure Windows to use a separate microphone or enable Bluetooth LE Audio stereo-with-microphone support; otherwise, treat this as an audio format, enhancement, or driver problem.

    If the headsets are Bluetooth

    Windows 11 automatically switches a Bluetooth Classic headset from high-quality stereo (A2DP) to the Hands-Free Profile (HFP) when Discord or a game opens its microphone. HFP provides simultaneous microphone and playback audio, but playback becomes lower-quality mono, which can sound heavily distorted. It switches back after the microphone closes.^1^

    Best workaround for Bluetooth Classic:

    1. Open Settings > System > Sound.
    2. Under Input, select the PC’s built-in microphone, a USB microphone, or another non-Bluetooth microphone.
    3. In Discord, open User Settings > Voice & Video and select that same device under Input Device.
    4. Keep the Bluetooth headset selected as the Output Device.
    5. Join a voice channel and test the game audio.

    Because the headset microphone is no longer opened, Windows should keep playback in its high-quality A2DP mode. Bluetooth Classic cannot provide stereo playback while its microphone is active.^2^

    If the headset and PC support Bluetooth LE Audio:

    1. Open Settings > System > Sound.
    2. Under Output, select the arrow beside the Bluetooth LE Audio device.
    3. Expand Output settings > Format.
    4. Set Format when microphone is active to Stereo (2 channels).
    5. Test Discord and the game.

    This option requires Windows 11 24H2 or later, factory-integrated Bluetooth LE support, compatible manufacturer drivers, and a Bluetooth LE Audio headset. If Format when microphone is active is absent, the system does not support this feature. If stereo causes glitches, change it to Mono (1 channel) for compatibility.^3^

    If the headsets are wired, USB, or the problem remains

    Since changing headsets did not help, test the shared Windows audio configuration:

    1. Go to Settings > System > Sound > Output, then select the active playback device.
    2. Set Audio enhancements to Off.
    3. Expand Advanced, change Default format to another available format, and retest while the microphone is active.^4^
    4. Press Start, type services.msc, and open it.
    5. Right-click Windows Audio and choose Restart.
    6. Right-click Windows Audio Endpoint Builder and choose Restart, then test again.

    If distortion continues:

    1. Open Settings > Windows Update > Check for updates and install available audio-related updates.
    2. Restart the PC.
    3. Open Device Manager > Sound, video and game controllers.
    4. Right-click the audio device and select Update driver > Search automatically for drivers.
    5. If no improvement, download the Windows 11 audio driver for the exact PC or motherboard model from its manufacturer.^5^

    The key detail for choosing the correct branch is whether both tested headsets were Bluetooth. If so, the microphone-triggered Bluetooth profile change is the first issue to address; if not, proceed directly to the enhancement, format, service, and driver steps.
