远程桌面协议^{(Remote Desktop Protocol)} ( RDP ) 是 Microsoft开发的专有协议，它为用户提供图形界面以通过网络连接连接到另一台计算机。用户为此目的使用RDP客户端软件，而另一台计算机必须运行^(RDP)RDP服务器软件。这篇文章旨在确定问题的原因以及解决方法，因为它涉及在Windows 10上播放声音时的^{(Windows 10)}RDP连接 (mstsc.exe) 内存问题。

启用声音时 RDP 连接断开

^(RDP)启用声音时RDP连接断开

让我们看一下您可能会遇到此RDP^(RDP)连接内存泄漏问题的典型场景。

在与 Windows 10 计算机的远程桌面连接 (mstsc.exe) 中^{(remote desktop connection (mstsc.exe) to a Windows 10 computer)}，当您播放任何声音时，连接会泄漏内存。这包括在 PC 扬声器上生成的简单哔声。

在这种情况下，mstsc.exe可能会突然断开连接并提示您重新连接到远程计算机。

MSTSC.exe创建与远程桌面会话主机^{(Desktop Session Host)}服务器或其他远程计算机的连接，编辑现有远程桌面连接(.rdp) 配置文件，并将使用^{(Remote Desktop Connection)}客户端连接管理器^{(Client Connection Manager)}创建的旧连接文件迁移到新的 .rdp 连接文件。

出现此问题的原因是远程桌面 ActiveX^{(Remote Desktop ActiveX)}控件Mstscax.dll为要在客户端计算机上播放的声音分配内存，但从不释放内存。这种内存不足的情况会导致远程桌面连接断开并自行重新启动。

^{(To work around)}要在Windows 10上^{(Windows 10)}RDP连接期间播放声音时解决此内存泄漏问题^{(memory leak issue)}，请重新连接到远程计算机。

请记住^(Bear)，由于这是一个新会话，您必须重新输入您的 RDP 凭据^{(re-enter your RDP credentials)}。

奖金信息^{(Bonus information)}

远程桌面连接^{(Remote Desktop Connection)}内置于 Windows 中，但也作为Windows 10 通用^(Universal)应用程序存在于Microsoft Store中。如果您想从非 Windows 设备访问和控制计算机，Microsoft 的RDC应用程序可用于 Mac、 iOS和 Android。

RDP connection disconnects when you enable Sound on Remote Desktop

Remote Desktop Protocol (RDP) is a proprietary protocol developed by Microsoft which provides a user with a graphical interface to connect to another computer over a network connection. The user employs RDP client software for this purpose, while the other computer must run RDP server software. This post is intended to identify the cause of the issue, as well as the workaround as it concerns RDP connection (mstsc.exe) memory issues when sound plays on Windows 10.

RDP connection disconnects when you enable Sound

Let’s take a look at a typical scenario where you can encounter this RDP connection memory leak issue.

In a remote desktop connection (mstsc.exe) to a Windows 10 computer, the connection leaks memory when you play any sound. This includes simple beep tones that are generated on the PC speaker.

In this situation, mstsc.exe may disconnect suddenly and prompt you to reconnect to the remote computer.

MSTSC.exe creates connections to Remote Desktop Session Host servers or other remote computers, edits an existing Remote Desktop Connection (.rdp) configuration file, and migrates legacy connection files that were created with Client Connection Manager to new .rdp connection files.

RDP connection (mstsc.exe) memory issues when sound plays

This issue occurs because the Remote Desktop ActiveX control, Mstscax.dll, allocates memory for the sound to be played on the client computer, but the memory is never released. This out-of-memory condition causes the remote desktop connection to disconnect and restart itself.

To work around this memory leak issue when sound plays during the RDP connection on Windows 10, reconnect to the remote computer.

Bear in mind that because this is a new session, you must re-enter your RDP credentials.

Bonus information

Remote Desktop Connection is built into Windows but also exists as a Windows 10 Universal app in the Microsoft Store. If you want to access and control a computer from a non-Windows device, Microsoft’s RDC app is available for Mac, iOS, and Android.
