Microsoft has confirmed that some applications can close unexpectedly when they rely on Windows to decode AC-3 (Dolby Digital) audio. Games are among the applications that may be affected, but this is not a finding that all games crash—or that the problem is limited to Windows 11 version 26H2. Microsoft identifies Windows 11 versions 24H2, 25H2 and 26H2 as affected after updates released on or after September 22, 2026.
What is causing the game crashes?
The confirmed issue involves Windows’ built-in decoder for AC-3, also known as Dolby Digital. Microsoft says some applications that require this decoding may close unexpectedly after installing updates released September 22, 2026, or later. The reported affected component is audio decoding; the notice does not identify a general problem with graphics drivers, game performance or every game.

Microsoft’s Windows 11, version 26H2 known-issues notice lists OS Build 26300.9550 and KB5124010 in its entry for the issue. The issue is also relevant to Windows 11 versions 24H2 and 25H2, not only 26H2.

Games are one possible category, alongside other applications that rely on Windows’ AC-3 decoding path. Microsoft says legacy applications are the most common users of this built-in audio-decoding component; many modern applications do not use it and are unlikely to encounter the issue.
#1 Best Overall
- PLUG IN AND HEAR SOUND IN SECONDS - USB Type-A connector with a 3.5mm stereo headphone output and a separate 3.5mm mono microphone input. No drivers, no software, no external power - the adapter is USB bus-powered and is recognized as a standard USB audio device.
- WORKS ON WINDOWS, MAC AND LINUX - Driverless on Windows 98SE/ME/2000/XP/Server 2003/Vista/7/8, Linux and Mac OSX, and compliant with the USB Audio Device Class 1.0 specification, so any system that supports class-compliant USB audio will see it. Select it as the sound output and input device after plugging it in.
- TWO JACKS, TWO JOBS - The green jack is stereo OUT for headphones or powered speakers; the pink jack is mono microphone IN for a 3.5mm mic. It does NOT support 4-pole headsets on a single combo plug, it does NOT power passive speakers, and it does NOT add surround sound - it is a stereo 2-channel adapter.
- FOR LAPTOPS AND DESKTOPS THAT NEED AN AUDIO PORT BACK - Adds a headphone and mic port to a laptop, desktop, or mini PC whose onboard jack has failed or was never there. Managed and work-issued computers can block new USB audio devices by policy - check with your IT department before ordering for a company machine.
- SABRENT SUPPORT AND WARRANTY - What is in the box: one USB audio sound adapter. Backed by a 1-year limited warranty, extended to 2 years when you register within 90 days on the manufacturer's website.
Depending on what an application is doing, it may fail to launch, close without warning, or continue working until a feature such as music playback is used. That variation means a crash occurring after an update is not, by itself, proof that the AC-3 issue is responsible.
Does 26H2 itself trigger the problem?
The relevant distinction is between the update that Microsoft associates with the regression and the later rollout of Windows 11 version 26H2. Microsoft identifies updates released from September 22 onward as the origin of the AC-3 issue. On September 29, Microsoft separately announced a controlled rollout of 26H2 to eligible 24H2 and 25H2 devices. The feature-update announcement does not mean 26H2 alone caused the bug: Microsoft’s affected-version list includes all three versions.

Microsoft said eligible devices may receive 26H2 through a small enablement package and that compatibility holds may be used during rollout. Those rollout details describe availability, not a separate fix for the audio-decoding problem. See Microsoft’s Windows 11 version 26H2 update history and its Windows Experience Blog announcement.
What has Microsoft said about a fix?
In its release-health entry, updated October 2, 2026, Microsoft said it was working on a resolution in a future Windows update. The notice did not provide a release date or a specific consumer workaround. Its status can change, so check the official release-health page for the latest update before changing system settings or uninstalling an update.

Are reports about specific games confirmed?
TechRadar reported individual complaints involving Fallout: New Vegas, The Elder Scrolls IV: Oblivion and Wardogs, with users associating crashes with the September preview update. Those reports are anecdotal: Microsoft’s notice does not name those games, establish that each crash was caused by AC-3 decoding, or quantify how many players are affected. TechRadar’s October 5 report is available here.
Neither Microsoft’s notice nor the reporting provides a measured count or share of affected users, games or crash events. A game crash after an update can have other causes, so the symptoms and timing alone cannot establish the cause.
