NAudio错误：“NoDriver call acmFormatSuggest” [英] NAudio error: "NoDriver calling acmFormatSuggest"

问题描述

我有一个项目，使用NAudio从mp3转换为wav。 （使用 WaveFormatConversionStream.CreatePcmStream（）方法）

它在我的开发机器上工作正常，但现在我尝试在一个新的新服务器，并抛出这个错误：

NAudio.MmException：NoDriver调用acmFormatSuggest

在NAudio.MmException.Try（MmResult结果，字符串函数）

在NAudio.Wave.Compression.AcmStream.SuggestPcmFormat（WaveFormat压缩格式）

在NAudio.Wave.WaveFormatConversionStream.CreatePcmStream（WaveStream sourceStream）

我认为NAudio在这里需要的一些依赖关系不在新服务器上。它是什么，我应该从哪里安装？

服务器是一个新鲜的Amazon EC2 Windows 2008 32位实例，包含Web服务器和应用服务器角色安装

解决方案

运行Windows 2008 R2，使用Naudio检测Wav和Mp3文件的长度，我遇到了问题。

我通过以下方式解决了这个问题： https://technet.microsoft.com/en-us/library/cc772567.aspx

本质上，安装桌面体验功能。

以上将需要重新启动服务器。

一旦安装了上述，需要启用任何进一步的，问题已解决。

I've got a project that uses NAudio to convert from mp3 to wav. (using the WaveFormatConversionStream.CreatePcmStream() method)

It worked fine on my development machine but now I'm trying it on a fresh new server and its throwing this error:

NAudio.MmException: NoDriver calling acmFormatSuggest
at NAudio.MmException.Try(MmResult result, String function)
at NAudio.Wave.Compression.AcmStream.SuggestPcmFormat(WaveFormat compressedFormat)
at NAudio.Wave.WaveFormatConversionStream.CreatePcmStream(WaveStream sourceStream)

I assume there is some dependency that NAudio needs here that isn't on the new server. What is it and where should I install it from?

Server is a freshly-hatched Amazon EC2 Windows 2008 32-bit instance with 'web server' and 'app server' roles installed.

解决方案

Running Windows 2008 R2, using Naudio to detect the length of Wav and Mp3 files, i ran into the same problem.

I solved this by following this: https://technet.microsoft.com/en-us/library/cc772567.aspx

Essentially, install the "Desktop Experience" feature.

The above will require a restart of the server.

Once the above was installed, i needed to enable nothing further, the problem was resolved.
