Nothing happens during network setup when playing back audio

Set the audio level on your PC, Mac or smartphone to maximum.
Check if the audio cable is firmly connected to both devices.
Do not playback other audio or video on your PC, Mac or smartphone during network setup.
If setting up a Wi-Fi connection, remove any ethernet LAN cable connected to your LiveShell 2.

Exit your web browser and access https://shell.cerevo.com/login again.

Echoing in Audio

Make sure you do not have the Dashboard main panel and the Ustream broadcast screen open at the same time in separate windows or tabs.
Close one of the screens or turn the volume in one of them down to zero, and then check again.
Turn the volume to zero for either screen using the Volume tab in the Dashboard main panel.

Can’t broadcast video and audio but Ustream site says “LIVE”

Make sure your video camera is powered ON and disable any auto power off functions.
Do not use Ustream Broadcaster at the same time as Dashboard.
Set another Ustream channel to your LiveShell 2 and check if you can broadcast without problem.

Livestream service compatability

LiveShell 2 supports only Original (http://original.livestream.com/guide/livetv) Livestream, not new Livestream.
New Livestream cannot be used with 3rd party encoders so LiveShell 2 cannot support it.
