HDMI connected TV

I would like to use mu Volumio RPi 4B connected to a TV via the RPi HDMI port. I believe TV will become a monitor, and upon starting up it will display the Volumio interface. I consider setting up the same HDMI Out port for Playback as output device. Am i correct here in my assumptions? Will it send the video and audio correctly?
The TV is connected on the backbone to a SONY soundbase with surround, similar as I am using it for the Playstation.

Solved myself. Need to install touchscreen plugin
