i stopped by the cockpit and asked if they'd have CH 9 on and they said sure. Didn't hear it. Later I also asked a FA to ask them and make sure and they said yes, everything was was on. But still nothing for the entire flight. Oh well.
A possible scenario: Captain flipped the "OBS ENT" switch on the overhead panel, to ON but the
#1 VHF radio volume was down on the left-side jumpseat position. That audio panel is what feeds ATC into the entertainment system.
