Improvements on USB Audio and Mute sync

Improvements:

• USB extending improved performance
• Support for Chrome OS Audio
• Improvements on Mute sync - Microsoft Teams, Zoom, and Skype for Business

Bug fix:

Fixed an issue with Barco ClickShare CX50, where the ANIUSB-MATRIX does not pass audio even if it is recognized

Known Issues:

• A pop noise is triggered when the channel is unrouted in Dante controller
• The file type is saved incorrectly and needs to be renamed to .json to be imported when exporting Presets using Safari on a Mac OS.
• When trying to load the device's web page after using SUU to upgrade or downgrade between MXA 4.3 and earlier releases, the browser may seem to be stuck on the "Loading" screen with the progress bar continually moving. This typically happens if two upgrades/downgrades are performed within a one-hour period. To correct this, hold your Shift key and click the Refresh button in your browser (or press Ctrl+Shift+R [Win] / Ctrl+F5 [Win] / Cmd+Shift+R [Mac]; note the keyboard shortcut doesn't work on Safari)
• The Shure Network Audio Encryption is not backwards compatible; all devices must have the version 4.1 firmware to use this feature
