Fixing Crackling Audio and Missing Sound in Games
Crackling is usually a sample rate mismatch and takes two minutes to fix. Missing audio is usually the wrong output device.
The short answer
Audio crackling in games is most commonly caused by a sample rate mismatch between Windows and the application, resolved by setting a consistent sample rate in the device's advanced properties. Complete absence of sound is usually the game outputting to a different device than the one in use, since Windows and individual games maintain separate output selections. Exclusive mode access by applications is the third common cause and produces intermittent silence.

Audio problems in games fall into two categories that people conflate constantly: distorted audio and absent audio. They have almost nothing in common.
Crackling is a format mismatch. Silence is usually a routing problem.
Two problems, two fixes
Crackling and popping means the signal is being converted badly. No sound at all means it is going somewhere else. Do not troubleshoot them together.
Step 1: Match the sample rate everywhere
Set a consistent sample rate 4 minutes
Right-click the speaker icon, open Sound settings, then find your output device's advanced properties. Set the default format to 24 bit, 48000 Hz, which matches what most games use. Then check any audio software you run, such as a headset control application, and set it to the same rate. Mismatches force real-time conversion, and under load that conversion produces the crackling.
If your headset has its own control software, that is a common source of the mismatch because it can override Windows independently.
Step 2: Check the per-app output device
Windows maintains a separate output device per application, which is genuinely useful and causes enormous confusion.
Open Sound settings and find the volume mixer or app volume preferences. Each running application appears with its own output selection. A game set to a device you unplugged will be silent while everything else works.
This happens most often after plugging in a headset while a game was already running.
Step 3: Disable exclusive mode and enhancements
In the same device advanced properties page:
Exclusive mode. Uncheck both options allowing applications to take exclusive control. When two applications both want it, one loses audio entirely, producing silence that appears random. Disabling costs a small amount of latency and removes a whole class of problems.
Audio enhancements. Turn them off. Spatial processing, loudness equalisation and bass boost all modify the signal and can interact badly with a game's own audio. This is a free diagnostic.
USB-specific crackling
If crackling only occurs on a USB headset, the cause is often the port rather than the software.
Plug directly into the machine rather than a hub, and preferably into a port on a different controller. USB audio is sensitive to bandwidth contention, and sharing a controller with a busy device produces exactly this.
Discord and voice chat interaction
Voice applications frequently take exclusive access or apply their own processing, and the interaction with a game's audio is a common source of problems.
The Discord issues guide covers the specific settings, and the audio setup guide covers building a chain that does not fight itself.

Frequently asked questions
What causes crackling audio specifically?
Most often a sample rate mismatch, where Windows outputs at one rate and the application expects another, forcing real-time conversion that produces artefacts under load. Setting both to the same rate eliminates it. The other common cause is a USB bandwidth or power issue on a shared controller, which produces similar symptoms.
Why does one game have no sound when everything else works?
Because Windows maintains a separate output device setting per application, and the game may be sending audio to a device you are not using. This is found in Sound settings under the volume mixer or app volume preferences. It happens most often after plugging in a new headset while a game was already running.
What is exclusive mode?
It allows an application to take sole control of the audio device, bypassing the Windows mixer for lower latency. When two applications both want exclusive access, one loses audio entirely, which produces intermittent silence that seems random. Disabling exclusive mode in the device properties resolves it at a small latency cost.
Do audio enhancements cause problems?
Frequently, yes. Spatial audio processing, loudness equalisation and bass boost all modify the signal in ways that can introduce distortion or interact badly with a game's own audio processing. Turning enhancements off is a standard early diagnostic and costs nothing to try.
