Known Issues/Requests

* Bluetooth Audio connections from a laptop are supported, but Bluetooth HFP (conferencing)
is not fully supported depending on the laptop hardware
* The use of external sound reinforcement speakers via AUX OUT is only recommended for
audio playback, not for audio conferencing, as it reduces the effectiveness of the AEC

Must be purchased separately
* Known Windows 10 issue with built-in Skype app which can cause an error which states

Skype or SfB app, or revert to earlier app revision

* Camera-in-use LED ring may not turn off immediately at the conclusion of a web conference
* Camera operates at 60Hz and may have lighting strobe effect in certain lighting environments
* Speaker volume control from laptops over USB is not supported. Must control volume on the Vibe via remote, side keypad on sound bar, or RS232.
