I’m having issues with choppy/stuttering audio, particularly on telemetry. It’s bad enough that it renders the CW ID meaningless.<o:p></o:p></p><p class="MsoNormal">My original thought was lack of CPU power, but I have tried it on a Raspberry Pi 2, Pi 3, and several virtual machines on a quad-core PC with identical results. Also, the choppiness is NOT as bad when using the full USB driver instead of SimpleUSB, which I believe conclusively rules out CPU power.<o:p></o:p></p><p class="MsoNormal">I’ve also tried a powered USB hub, thinking that the USB device was not receiving enough power, with no improvement.<o:p></o:p></p><p class="MsoNormal">I’ve used the Android mobile app to connect to the node, and the telemetry does not seem to be choppy when listening to it over the app. While I need to do some more testing to say this conclusively, I do believe at this point that my issue is narrowed down to the USB fob itself and/or the specific audio stream being sent to the device.<o:p></o:p></p><p class="MsoNormal">I’m currently searching for a way to alter the sample rate that ASL is sending the audio to the device in.<o:p></o:p></p><p class="MsoNormal">Has anyone experienced this, and does anyone have any suggestions?<o:p></o:p></p><p class="MsoNormal"><o:p> </o:p></p><p class="MsoNormal">Thanks and 73,<o:p></o:p></p><p class="MsoNormal"><o:p> </o:p></p><p class="MsoNormal">Rob, WX1N<o:p></o:p></p></div></div></blockquote><blockquote type="cite"><div dir="ltr"><span>_______________________________________________</span><br><span>App_rpt-users mailing list</span><br><span><a href="mailto:App_rpt-users@lists.allstarlink.org">App_rpt-users@lists.allstarlink.org</a></span><br><span><a href="http://lists.allstarlink.org/cgi-bin/mailman/listinfo/app_rpt-users">http://lists.allstarlink.org/cgi-bin/mailman/listinfo/app_rpt-users</a></span><br><span></span><br><span>To unsubscribe from this list please visit <a href="http://lists.allstarlink.org/cgi-bin/mailman/listinfo/app_rpt-users">http://lists.allstarlink.org/cgi-bin/mailman/listinfo/app_rpt-users</a> and scroll down to the bottom of the page.
