Playing wav/mp3 from Windows 7 service - c#-4.0

Question

I need to play a sound file (wav or mp3 is fine) from a service in Windows 7/2008... the way we did it in WinXP doesn't work anymore. I've followed this question Play wave file from a Windows Service (C#) with no success, in various combinations. The sound plays fine through the debugger but once I install it as a service it doesn't play, and event logs prove the call is being made. I've also followed the http://bresleveloper.blogspot.co.il/2012/06/c-service-play-sound-with-naudio.html link with the same result.
Code snippet follows below. It is a C# service with VS 2010, .Net 4.0, NAudio 1.5.4.0. I am using
InstallUtil to install/remove the service.
WRT the code, I comment out the Wav or MP3 stuff and one of the methods each time... they all play the sound sucessfully.
static class Program
{
[DllImport("kernel32.dll")]
public static extern Boolean AllocConsole();
static void Main(string[] args)
{
m_eventLog = new EventLog();
m_eventLog.Source = "EventLoggerSource";
if(args.Length > 0 && args[0].ToLower() == "/console")
{
AllocConsole();
EventLoggerApp app = new EventLoggerApp();
app.Start();
m_eventLog.WriteEntry("INFO (Calling Player)");
string fileFullPath=#"c:\aaasound\bunny_troubles.wav",fileFullPath2=#"c:\aaasound\dreams.mp3";
// Wav file
IWavePlayer wavePlayer=new WaveOutEvent(); // Method 1
IWavePlayer wavePlayer=new WasapiOut(NAudio.CoreAudioApi.AudioClientShareMode.Shared,false,100); // Method 2
AudioFileReader audioFile=new AudioFileReader(fileFullPath);
audioFile.Volume = (float)1.0;
wavePlayer.Init(audioFile);
// MP3 file
IWavePlayer wavePlayer=new WasapiOut(NAudio.CoreAudioApi.AudioClientShareMode.Shared,true,100); // Method 1- EventSync/not both work
IWavePlayer wavePlayer=new WasapiOut(NAudio.CoreAudioApi.AudioClientShareMode.Exclusive,false,100); // Method 2- EventSync must be false or throws an exception
WaveStream mp3Reader = new Mp3FileReader(fileFullPath2);
WaveChannel32 inputStream=new WaveChannel32(mp3Reader);
WaveStream wavStream=new WaveChannel32(inputStream);
wavePlayer.Init(wavStream);
//this.wavePlayer.PlaybackStopped += new EventHandler(wavePlayer_PlaybackStopped);
wavePlayer.Play();
while(wavePlayer.PlaybackState == PlaybackState.Playing)
{
Thread.Sleep(100);
}
