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

问题描述

我有一个使用 NAudio 将 mp3 转换为 wav 的项目.(使用 WaveFormatConversionStream.CreatePcmStream() 方法)

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

它在我的开发机器上运行良好，但现在我在一个全新的服务器上尝试它并抛出此错误:

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 调用 acmFormatSuggest
在 NAudio.MmException.Try(MmResult 结果，字符串函数)
在 NAudio.Wave.Compression.AcmStream.SuggestPcmFormat(WaveFormatcompressedFormat)
在 NAudio.Wave.WaveFormatConversionStream.CreatePcmStream(WaveStream sourceStream)

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)

我假设 NAudio 需要的一些依赖项不在新服务器上.它是什么，我应该从哪里安装它?

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?

服务器是一个新孵化的 Amazon EC2 Windows 2008 32 位实例，安装了Web 服务器"和应用服务器"角色.

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