title: NAudio error: "NoDriver calling acmFormatSuggest"
body: <p>I've got a project that uses NAudio to convert from mp3 to wav. (using the <code>WaveFormatConversionStream.CreatePcmStream()</code> method)</p>
  
  <p>It worked fine on my development machine but now I'm trying it on a fresh new server and its throwing this error:</p>
  
  <blockquote>
    <p>NAudio.MmException: NoDriver calling acmFormatSuggest<br>
      at NAudio.MmException.Try(MmResult result, String function)<br>
      at NAudio.Wave.Compression.AcmStream.SuggestPcmFormat(WaveFormat compressedFormat)<br>
      at NAudio.Wave.WaveFormatConversionStream.CreatePcmStream(WaveStream sourceStream)  </p>
  </blockquote>
  
  <p>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?</p>
  
  <p>Server is a freshly-hatched Amazon EC2 Windows 2008 32-bit instance with 'web server' and 'app server' roles installed.</p>
