Windows USB Sound Levels Bug Fix

[VK4GHZ]

Watch the first 7 minutes at least!

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 PCM2904 and below, pre-C revisions.

A non-exhaustive list of devices using this chip and therefore have the bug guaranteed:
• All Icoms with built in USB Audio
• All Kenwoods with built in USB Audio
• All Yaesus with built in USB Audio, as well as the SCU-17 Interface
• All Signalink USB's

There is also a permanent fix possible by swapping ICs to one that enumerates as a line-in device not a microphone device:
