    <p>I need to play single sound repeatedly in my app, for example, a gunshot, using XAudio2.</p> <p>This is the part of the code I wrote for that purpose:</p> <pre><code>public sealed class X2SoundPlayer : IDisposable { private readonly WaveStream _stream; private readonly AudioBuffer _buffer; private readonly SourceVoice _voice; public X2SoundPlayer(XAudio2 device, string pcmFile) { var fileStream = File.OpenRead(pcmFile); _stream = new WaveStream(fileStream); fileStream.Close(); _buffer = new AudioBuffer { AudioData = _stream, AudioBytes = (int) _stream.Length, Flags = BufferFlags.EndOfStream }; _voice = new SourceVoice(device, _stream.Format); } public void Play() { _voice.SubmitSourceBuffer(_buffer); _voice.Start(); } public void Dispose() { _stream.Close(); _stream.Dispose(); _buffer.Dispose(); _voice.Dispose(); } } </code></pre> <p>The code above is actually based on SlimDX sample.</p> <p>What it does now is, when I call Play() repeatedly, the sound plays like:</p> <blockquote> <p>sound -> sound -> sound</p> </blockquote> <p>So it just fills the buffer and plays it.</p> <p>But, I need to be able to play the same sound <strong>while</strong> the current one is playing, so effectively these two or more should mix and play at the same time.</p> <p>Is there something here that I've missed, or it's not possible with my current solution (perhaps SubmixVoices could help)? </p> <p>I'm trying to find something related in docs, but I've had no success, and there are not many examples online I could reference.</p> <p>Thanks.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
