Bug & Fix for Digital Modes

(Note: Before making this post, I asked 2 Club members to verify that this is a “real” issue and received confirmation.  Ro K4HRM).

There’s a bug with the USB audio chipset used in many ham radio sound interfaces that occurs in Windows Vista and later. The affected chipset is the TI PCM2900 series, pre-C revisions.  A non conclusive list of devices using this chip line are all Icoms with built in USB sound interfaces(7100/7200), all Kenwoods with built in usb sound interfaces (590), several Yaesus, the MicroHam USB III and all Signalinks.
