连接到特定基于英特尔的设备时，USB连接的音频或视频设备会发生故障。 - Windows Client

本文提供了影响特定基于 Intel 的设备的问题的解决方法和修补程序。 附加到受影响设备的 USB 音频或视频设备可能无法正常工作。 这些 USB 设备包括相机、扬声器、麦克风和耳机。

症状

你遇到以下一个或多个症状：

• 在音频流中，你可能会听到偶尔出现的问题或意外噪音，例如单击声或爆裂声。
• 在视频流中看到瞬间可见的瑕疵。
• USB 音频或视频设备停止工作。

受影响的设备

此问题会影响使用具有离散受信任平台模块（dTPM）芯片的 500、600、700 系列平台控制器集线器的基于 Intel 的系统。 使用固件 TPM （fTPM） 技术的计算机不受此问题的影响。

解决方法

若要解决此问题，请执行以下步骤：

1. 拔下设备，然后将其重新附加到计算机。
2. 如果步骤 1 不起作用，请重新启动计算机。

原因

此问题是由于 Windows 与离散 TPM 进行通信时，内部硬件总线上出现延迟所引发的。 这些延迟反过来又会延迟与 USB 控制器的通信，并在 USB 总线上生成拆分事务错误。 因此，时间敏感的 USB 流量（如音频和视频流式处理）可能会遇到故障或错误。

决议

重要

此部分（或称方法或任务）介绍了修改注册表的步骤。 如果您错误地修改注册表，可能会出现严重问题。 因此，请确保仔细执行这些步骤。 出于防范目的，请在修改之前备份注册表，以便在出现问题时还原注册表。 有关如何备份和恢复注册表的更多信息，请参见如何在 Windows 中备份和恢复注册表。

Windows 11 版本 24H2 的 2025 年 10 月更新和 Windows 11 版本 23H2 的 2025 年 11 月更新引入了此硬件问题的修补程序。 若要使用此修补程序，请执行以下步骤：

1. 在受影响的设备上，安装最新的更新。 如有必要，请重启设备。

2. 验证设备是否使用 dTPM 而不是 fTPM。 若要查找此信息，请检查设备 BIOS 设置或联系设备制造商。

3. 在本文的“ 详细信息 ”部分中运行诊断脚本。

   此脚本检查修补程序是否适用于设备。

4. 创建以下注册表项：

   • 子项： HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Tpm
   • 类型： REG_DWORD
   • 名称： TPMDriverReadAfterWriteCount
   • 值： 0x1 （1）

   例如，打开管理命令提示符窗口，然后运行以下命令：

   reg.exe ADD HKLM\SYSTEM\CurrentControlSet\Control\Tpm /v TPMDriverReadAfterWriteCount /t REG_DWORD /d 1
   

详细信息

可以使用以下 Windows PowerShell 脚本来确定电脑是否具有可能受到影响的控制器之一。 若要运行此脚本，请创建使用名称（如 Check-USBSplitTransactionVulnerability.ps1）的文件。 然后，将以下文本粘贴到文件中，并在 PowerShell 命令提示符下运行脚本。

注释

在 Device Manager 中，有问题的设备显示在 **“系统设备”**下。 它具有类似于“Intel（R） LPC 控制器/eSPI 控制器”的名称。
