Searching in the source of PWLib and on comments on the internet, I discourage the use of DirectSound for now...<div><br></div><div>&gt;&gt; No DirectShow code yet on sources and DirectShow being replaced by DXVA (DirectX Video Acceleration)</div>
<div>&gt;&gt; DirectSound being replace by XNA Audio: XACT2 (Cross Audio Creation Tool 2)</div><div>&gt;&gt; Windows Vista and .Net 3.5 (WDDM drivers) fallback to software mixer until specific accelarated drivers are made by vendors</div>
<div><br></div><div>Installing 2Gb of DirectX old SDK (today is november_dx10 SDK, dx11 preview) only to have access to sound is a pain....</div><div><br></div><div>Other thing: adding the Error String header or Util header to the production code implies in redistribute of the dx#.dll. It is a back of the &nbsp;DLL Hell pain because each year 2 or 3 versions of SDK are made, many versions of&nbsp;dx#.dll are avaible (four versions -or more- for DX9SDK, for example fev., ago., oct., nov.)</div>
<div><br></div><div>PS.: Now I remembered, really the source for PWLib can be the h323plus site, no CVS repository for that.<br><br><div class="gmail_quote">2008/11/28 JobsGuo(Guo Huayong) <span dir="ltr">&lt;<a href="mailto:ghyhust@126.com">ghyhust@126.com</a>&gt;</span><br>
