c# - NAudio error: "NoDriver calling acmFormatSuggest"

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.

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.
