<div dir="auto">As I understand things, the Windows OS APIs (software interfaces) that control the sound card functions like "mute mic" were completely changed after Windows XP, and 100% backwards compatibility with old sound card applications like Win-Test and sbrdchk was never provided by Microsoft.<div dir="auto"><br></div><div dir="auto">They expected application developers to migrate to the "new" sound card APIs and libraries, but that requires Win-Test code changes, <i>and</i> a completely new development environment, <i>and</i> a complete recompile and retest of all Win-Test code. That is not going to happen any time soon (if ever).</div><div dir="auto"><br></div><div dir="auto">In other words, the "Mute MIC when the DVK is playing" option of Win-Test does not work any more, except on Windows XP, and it cannot be easily fixed.</div><div dir="auto"><br></div><div dir="auto">Depending on your radio type, consider using the radio's built-in sound card or voice memories instead of using a PC sound card. This will usually mute the radio's mic line. Scripts support this. See <a href="https://bit.ly/wtscripts">https://bit.ly/wtscripts</a> .</div><div dir="auto"><br></div><div dir="auto">But note that voice memories do not work well with the Advanced SO2R scenarios, because Win-Test does have built-in code to support voice memory events. And since Win-Test only supports one sound card as a DVK, there is no way to use two sound cards, one inside each radio, with the Advanced SO2R scenarios, unfortunately.</div><div dir="auto"><br></div><div dir="auto">The only way to mute the mic when a message is playing would be via a hardware relay to open the mic. line, plus some scripts to toggle a pin on a dedicated serial port during all message transmissions, but I don't think anyone has ever tried to do that. </div><div dir="auto"><br><div data-smartmail="gmail_signature" dir="auto">73,<br>Bob, N6TV</div></div><br><div class="gmail_extra" dir="auto"><br><div class="gmail_quote">On Aug 15, 2017 12:15 AM, "Thomas Fricke" <<a href="mailto:t.fricke@imgromex.de">t.fricke@imgromex.de</a>> wrote:<br type="attribution"><blockquote class="quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div lang="DE" link="#0563C1" vlink="#954F72"><div class="m_2060906047324830096WordSection1"><p class="MsoNormal">Hi @all,<u></u><u></u></p><p class="MsoNormal"><u></u> <u></u></p><p class="MsoNormal"><span lang="EN-GB">I know there was a thread of SM5AJV in 2011.
