Hello,
I have an old TV with such a set of inputs:

The TV does not have a built-in DVB-T tuner, therefore the external tuner is connected using an HDMI cable with an adapter to DVI and separately "cinch" audio cables.
I would like to change the tuner to Ferguson FBOX 3 TV whose inputs / outputs look like this:

This tuner has no JACK or cinch audio outputs, so I would like to ask how best to transmit the audio signal to the TV?
Assuming the image will be uploaded as before.
Is it a good solution to connect the S / PDIF output on the tuner with the JACK input on the TV with an adapter?
And an additional question about the antenna input and output on the tuner:
Will I get HD quality by connecting the tuner to the TV with an ordinary antenna cable?
