Commented Unassigned: Not available for Windows Phone 8 projects? [16444]
Trying to create a universal Windows 8/WP8 app, but I can't add Naudio package to WP8.1 project.
Is WP8 unsupported? Will it be supported anytime soon?

Comments: I'd love to add WP8.1 support, but time is limited at the moment. Hopefully it will be easier now that we've added WinStore support as I understand that the WP8.1 API is getting much closer to the Windows Store one.

Created Unassigned: Audio path permanently lost to instance of an application [16446]
I am building a Windows Forms application that uses NAUDIO to record / play audio tracks.
During testing on Windows 7 we disabled all input devices (mics) and tried to record some audio.

Comments: hi, yes the mixer APIs ought to be able to find this control, but in practice it can be very hard to do. Easiest thing is just to experiment with the mixer API controls and see if you can find the control you are after.

Created Unassigned: Bug in WaveFileReader if opening invalid RIFF file by filename [16448]
The WaveFileReader constructor that opens a file using a filename calls into the other constructor taking a stream. This other constructor calls a method to verify the RIFF header, but when this fails, an exception is thrown back to the caller.
This has the unfortunate effect that the first constructor, given the filename, doesn't get a chance to close the stream it opened. The stream is thus left open until GC or similar takes care of it.
The best way to handle this would be to do the following:
1. Refactor out the contents of the constructor taking a stream into a new, private, constructor, that also takes the `ownInput` value as a parameter.
2. Change the two existing constructors to chain to the new one, passing true/false for that new parameter as appropriate
3. The new constructor would have a try/catch block around it (or at least around the stream construction and RIFF header check), and if exception was thrown in the RIFF header validation, and ownInput is true, dispose of the stream before throwing the exception up the chain.

Created Unassigned: Playing Microsoft TTS with WASAPI [16449]
Hallo,
I have a problem playing Microsoft Text to Speech with WASAPI. I basically get an error (Not a WAVE file - no RIFF header) when the WaveFileReader tries to read the audioStream. As you can see in the code below I tried to convert the audioStream coming from Microsoft Text to Speech but it doesn't work.
```
using (SpeechSynthesizer synth = new SpeechSynthesizer())
using (MemoryStream streamAudio = new MemoryStream())
{
// Create a SoundPlayer instance to play the output audio file.
System.Media.SoundPlayer m_SoundPlayer = new System.Media.SoundPlayer();
SpeechAudioFormatInfo speechFormat = new SpeechAudioFormatInfo(EncodingFormat.Pcm, 32000, 8, 2, 8000, 2, null);
//synth.SelectVoice(AppSettings.VoiceName);
// Configure the synthesizer to output to an audio stream.
synth.SetOutputToAudioStream(streamAudio,speechFormat);
// Speak a phrase.
synth.Speak("Hallo Jonas wie gehts es dir?");
streamAudio.Position = 0;
synth.SetOutputToNull();
_wasapiOut = new WasapiOut(device, AudioClientShareMode.Shared, false, 2000);
RawSourceWaveStream s = new RawSourceWaveStream(streamAudio, new WaveFormat(32000, 8, 2));
WaveStream ws = WaveFormatConversionStream.CreatePcmStream(s);
_reader = new WaveFileReader(streamAudio);
_wasapiOut.Init(_reader);
_wasapiOut.Play();
}
```
I hope somebody can help me :)

Edited Unassigned: Playing Microsoft TTS with WASAPI [16449]
Hallo,
I have a problem playing Microsoft Text to Speech with WASAPI. I basically get an error (Not a WAVE file - no RIFF header) when the WaveFileReader tries to read the audioStream. As you can see in the code below I tried to convert the audioStream coming from Microsoft Text to Speech by using the RawSourceWaveStream and the WaveFormatConversionStream. Unfortunately that doesn't work. I need to play the audio with WASAPI because I want to select a specific device to play the audio with.
```
using (SpeechSynthesizer synth = new SpeechSynthesizer())
using (MemoryStream streamAudio = new MemoryStream())
{
// Create a SoundPlayer instance to play the output audio file.
System.Media.SoundPlayer m_SoundPlayer = new System.Media.SoundPlayer();
SpeechAudioFormatInfo speechFormat = new SpeechAudioFormatInfo(EncodingFormat.Pcm, 32000, 8, 2, 8000, 2, null);
//synth.SelectVoice(AppSettings.VoiceName);
// Configure the synthesizer to output to an audio stream.
synth.SetOutputToAudioStream(streamAudio,speechFormat);
// Speak a phrase.
synth.Speak("Hallo Jonas wie gehts es dir?");
streamAudio.Position = 0;
synth.SetOutputToNull();
_wasapiOut = new WasapiOut(device, AudioClientShareMode.Shared, false, 2000);
RawSourceWaveStream s = new RawSourceWaveStream(streamAudio, new WaveFormat(32000, 8, 2));
WaveStream ws = WaveFormatConversionStream.CreatePcmStream(s);
_reader = new WaveFileReader(streamAudio);
_wasapiOut.Init(_reader);
_wasapiOut.Play();
}
```

Comments: I solved it. I had to set the Encoding of the SpeechAudioFormatInfo to ALaw and the RawSourceWaveStream has to instantiate also a Alaw Format. The WaveFileReader is then pointless and wasapi can simply Init it. ``` ALawFormat = new SpeechAudioFormatInfo(EncodingFormat.ALaw, 44100, 8, 1, 1, 2, null); ... RawSourceWaveStream s = new RawSourceWaveStream(memoryStream, WaveFormat.CreateALawFormat(44100, 1)); ws = WaveFormatConversionStream.CreatePcmStream(reader); _wasapiOut.Init(ws); _wasapiOut.Play(); ```

Comments: not at the moment I'm afraid. Also, make sure it really is normalization you want. Usually a limiter or compressor is a more appropriate choice
