I ran these fixes against OBS Studio 32.2.2, the current stable build, on both a fresh Windows 11 install and an older machine running Realtek onboard audio with Nahimic installed — the combination that causes the most support-forum complaints. One thing worth knowing before you start: right after you switch the Desktop Audio device in Settings, the meter in the Audio Mixer sometimes sits flat at 0 dB for a couple of seconds even though the device is working fine. It’s a UI refresh delay, not a failed fix, but it’s exactly the kind of thing that makes people assume they’ve done something wrong and start randomly toggling settings. Give it five seconds before you decide a step didn’t work.

Why OBS Stops Capturing Desktop Audio

“Desktop audio not working in OBS” almost never means OBS itself is broken. It means one of a handful of settings — inside OBS, inside Windows, or in a third-party audio manager — is pointing somewhere your actual sound isn’t going. Here’s the breakdown of where the problem usually sits:

Step-by-Step: Getting Desktop Audio Working Again

Work through these in order. Most people are fixed by Step 3; the rest are for the stubborn cases where the meter looks fine but the recording still comes out silent.

Step 1 — Confirm OBS Is Listening to the Right Device

Open OBS Studio, click Settings, then go to the Audio tab. Under Global Audio Devices, find Desktop Audio and set it to whatever device you currently use to hear sound — your speakers, a USB headset, Bluetooth headphones, or an audio interface. If you’re not sure, pick whichever device plays Windows notification sounds and YouTube audio right now. Click Apply, then OK.

Step 2 — Watch the Audio Mixer Meter While Sound Plays

Back in the main OBS window, look at the Audio Mixer panel at the bottom. You should see a Desktop Audio fader. Play a YouTube video or any music while watching that meter. If the green bar moves, OBS is receiving your desktop audio at the source level. While you’re there, double-check Desktop Audio isn’t muted (the speaker icon shouldn’t have a line through it) and the volume slider isn’t dragged all the way down — both reset occasionally after a Windows audio device change.

Step 3 — Check Your Output Mode and Active Audio Tracks

This is the step most guides skip, and it’s the one that explains the most confusing version of this problem: the meter moves, but the finished recording is silent. Go to Settings > Output and set Output Mode to Advanced if it isn’t already. Under the Recording or Streaming tab (whichever applies), check which audio track is actually selected for that output. OBS supports up to six separate audio tracks — useful for splitting mic, desktop audio, and background music into different channels — but your media player usually only plays one track by default when you open the file. That means OBS can be recording your desktop audio perfectly while the video still appears to have no sound, simply because you’re listening back on a track Desktop Audio was never assigned to.

Step 4 — Fix Track Assignment in Advanced Audio Properties

In the Audio Mixer, click the three dots (or the gear icon, depending on your OBS version) next to Desktop Audio and choose Advanced Audio Properties. Find the Desktop Audio row and look at the track checkboxes. Make sure Desktop Audio is enabled on the same track number your recording or stream output uses — if your output is set to Track 1, Desktop Audio needs Track 1 checked too. This is easy to overlook because the meter in the main mixer looks completely normal regardless of which track is ticked; the routing problem is invisible until you actually play back the file.

Step 5 — Check the Windows Volume Mixer

Right-click the speaker icon in the Windows taskbar and open Volume Mixer. Scroll through the per-app list and find OBS Studio. It’s surprisingly common for OBS to end up muted or turned down here, especially after a Windows update resets app-level audio permissions. Unmute it, pull the slider up, and close the window.

Step 6 — Turn Off Exclusive Mode on Your Playback Device

If the meter doesn’t move at all, no matter what you select, another application may be holding exclusive control of the audio device. In Windows, open Sound settings > More sound settings (or search “Sound Control Panel”), right-click your playback device, choose Properties, and open the Advanced tab. Uncheck Allow applications to take exclusive control of this device. This single checkbox resolves a large share of “OBS detects nothing at all” cases, particularly with gaming headsets that enable exclusive mode by default.

Step 7 — Close or Disable Third-Party Audio Enhancement Software

Tools like Nahimic (common on MSI and Acer laptops), ASUS Sonic Studio, and Realtek’s own “audio enhancements” sit between Windows and your sound card, and they’re known to intercept or filter the stream before OBS ever sees it. If you’ve got one of these installed, temporarily close it from the system tray or disable its enhancement effects and retest. You don’t need to uninstall it — just make sure it isn’t active while you’re recording or streaming.

Step 8 — Update Your Audio Drivers

An outdated or corrupted audio driver can silently drop a device from OBS’s list or cause intermittent dropouts mid-recording. Check Windows Update > Advanced options > Optional updates for a driver update first — it’s free and usually enough. If that comes up empty, grab the latest driver directly from your motherboard, laptop, or sound card manufacturer’s support page rather than a generic driver-updater tool, which can install mismatched versions.

Step 9 — Run OBS as Administrator

It’s a smaller fix, but it works often enough to be worth the ten seconds: search for OBS Studio in the Start menu, right-click it, and choose Run as administrator. Some audio drivers restrict device access to elevated processes, which quietly blocks OBS from reading the stream even though everything else looks correctly configured.

Step 10 — Restart the Windows Audio Service

If nothing above has worked, the Windows Audio service itself may have stalled. Press Win + R, type services.msc, find Windows Audio, right-click it, and select Restart. This resets every audio-related connection on the system, OBS included, without requiring a full reboot.

Run a Short Test Recording Before You Trust It

Once the meter is moving and your tracks are assigned correctly, don’t jump straight into a 40-minute stream. Record 15–20 seconds, stop, and play it back. This single habit saves more wasted recording sessions than any setting on this page — it confirms desktop audio and microphone are both actually landing in the file before you commit real time to it.

How Often Each Cause Shows Up

This isn’t a precise survey — it’s a pattern based on OBS community reports and our own testing across different setups. Treat it as “where to look first,” not a guarantee.

If your recording setup also has you juggling a second microphone or a USB Wi-Fi adapter plugged in alongside a USB audio interface, it’s worth knowing that USB bandwidth contention can cause similar-looking dropouts — our guide on fixing USB devices not recognized in Windows 11 covers the port and power-management settings that affect this too.

Watch It Fixed: Step-by-Step Video Walkthrough

If you’d rather watch someone click through the exact settings instead of reading, this walkthrough from Slurp Tech covers the same Desktop Audio device and mixer checks in a live OBS session and is a useful companion to the steps above.

While you’re setting up your recording environment, a laptop running hot under load can also introduce audio stutter that looks like a capture problem but isn’t — see our guide on fixing a loud, overheating laptop fan if your system is thermal-throttling during long streams. And if OBS itself becomes sluggish or the whole app stalls mid-session, check System Interrupts high CPU usage, which can starve audio threads of processing time and produce exactly this kind of silent-recording symptom.

Other Things Worth Checking

A few less common causes that don’t fit neatly into the steps above but are worth ruling out:

• If you recently updated Windows, check that it didn’t reset your default playback device — OBS’s “Default” option in the device dropdown follows whatever Windows currently considers default, which can silently change after an update.
• If you’re recording to an external or network drive and audio cuts out partway through, the bottleneck may not be audio at all — see our guide on an external hard drive not showing in Disk Management if your recording destination keeps disconnecting.
• Bluetooth headsets and earbuds often switch Windows into a lower-quality “hands-free” audio profile when a microphone is active, which can thin out desktop audio in OBS. Our Bluetooth audio stuttering on Windows guide walks through fixing that profile switch.
• If OBS or Windows Update itself fails to install correctly, driver updates for your audio hardware may silently fail too — our Windows Update error 0x80070002 fix covers clearing that blockage.
• A failing or outdated audio driver occasionally shows up alongside unrelated blue-screen errors; if you’ve also seen crashes, check our DRIVER_IRQL_NOT_LESS_OR_EQUAL fix before assuming it’s an OBS-only issue.

When to Call In a Professional

Most Desktop Audio issues are solved by the steps above. But if you’ve gone through every one of them, your audio device isn’t even showing up in Windows’ own Sound settings, or you’re hearing crackling and dropouts system-wide (not just in OBS), that points to a hardware or driver-level fault rather than an app setting. At that point, it’s worth contacting your PC or laptop manufacturer’s support line, or a local technician who can test the audio hardware directly — pushing further through software settings alone won’t fix a failing sound chip or a corrupted driver stack that reinstalling can’t repair. If your setup also involves random shutdowns while gaming or streaming, treat that as a separate hardware signal worth investigating alongside the audio issue, not after it.

FAQ

Why does OBS show the Desktop Audio meter moving but the recording has no sound?

This almost always means your audio tracks don’t match. The meter confirms OBS is receiving the signal, but Desktop Audio may be assigned to a track your recording or stream output isn’t using. Fix it in Advanced Audio Properties by matching Desktop Audio’s track number to your output’s active track.

Why is OBS not detecting any desktop audio at all?

Start with the device dropdown in Settings > Audio — the wrong device is the single most common cause. If the correct device is selected and the meter still won’t move, check for exclusive mode being enabled on that device, and close any audio enhancement software like Nahimic or Sonic Studio that might be intercepting the stream.

Does OBS Studio cost anything to use?

No. OBS Studio is free, open-source software with no license fee, subscription, or paid tier. Every fix in this guide uses settings already built into the free app — you don’t need to buy anything to solve a desktop audio problem.

Can Windows updates break OBS desktop audio?

Yes. A Windows update can reset your default playback device or push a new audio driver that doesn’t match your hardware correctly. If desktop audio stopped working right after an update, re-check your device selection in OBS first, then look at Optional Updates for a corrected driver.

Should I use “Default” or a named device for Desktop Audio in OBS?

Selecting your device by name rather than “Default” is more reliable. “Default” follows whatever Windows currently considers the system default, which can change automatically when you plug in headphones or a new device — silently redirecting OBS away from the audio you actually want captured.

Conclusion

Desktop audio problems in OBS Studio are almost never a broken app — they’re a mismatch somewhere in the chain between your Windows playback device and the track your recording actually uses. Work through the device, the mixer meter, the track assignment, and the Windows-level settings in that order, and you’ll find the break faster than randomly toggling options. Once the meter moves and a short test recording actually has sound in it, you’re set — and you’ll know exactly where to look if it happens again.
