Commented Unassigned: MixingSampleProvider+Waveout does not work [16484]

Hello,

i am using the MixingSampleProvider for multiple Inputs.
```
BufferedWaveProvider dummy = new BufferedWaveProvider(new WaveFormat(48000, 16, 1));

MixingSampleProvider ss = new MixingSampleProvider(WaveFormat.CreateIeeeFloatWaveFormat(48000, 1));

ss.AddMixerInput(dummy);
WaveOut waveOut = new WaveOut();
waveOut.Init(ss);
waveOut.Play();
```
undefinied error while waveoutopen.interop


```
I think the floatWaveFormat is the reason, the same Code above works fine without the MixingSampleProvider.

waveOut.Init(dummy);
waveOut.Play();
```






But when i use DirectSound as waveOut both Codes are ist working fine.

Why?



Comments: very strange. I suspect it is a limitation in your soundcard drivers. Make sure they are up to date.
