Ref. to Voice4video issue

Hi community,

 

I have a new Soundbar 300 and struggling with Voice4video install. It found the TV (QLED '21) and following such the application asks me to Setup Cable box, however I have none, I only have an CI card to interface with the cable provider. What should I chose as Cable box to finish the setup?

 

Also unlike the BOSE TV speaker, the Soundbar 300 experiences a delay of 3-4 sec on starting the TV until audio is heard. The speaker is connected to the TV using HDMI. Is this normal? Am I missing some option which would enable immediate response when opening the TV just like TV Speaker? 

 

Thank you,

Radu
