This C# code shows you how to add the new audio frame with the embedded audio, trim it, and set the fade duration:

```c#
using (Presentation pres = new Presentation())
{
IAudio audio = pres.Audios.AddAudio(File.ReadAllBytes("sampleaudio.mp3"));
IAudioFrame audioFrame = pres.Slides[0].Shapes.AddAudioFrameEmbedded(50, 50, 100, 100, audio);

// Sets the start trimming duration to 1.5 seconds
audioFrame.TrimFromStart = 1500f;
// Sets the end trimming duration 2 seconds
audioFrame.TrimFromEnd = 2000f;

// Sets the duration of the starting fade for 200ms
audioFrame.FadeInDuration = 200f;
// Sets the duration of the ending fade for 500ms
audioFrame.FadeOutDuration = 500f;

pres.Save("AudioFrameTrimFade_out.pptx", SaveFormat.Pptx);
}
```

The following code sample demonstrates how to get the audio frame with the embedded audio and change its volume to 85%:

```c#
using (Presentation pres = new Presentation("AudioFrameEmbed_out.pptx"))
{
// Gets the AudioFrame shape
AudioFrame audioFrame = (AudioFrame)pres.Slides[0].Shapes[0];

// Sets the audio volume to 85%
audioFrame.VolumeValue = 85f;

pres.Save("AudioFrameValue_out.pptx", SaveFormat.Pptx);
}
```
