Bush sound bar

[Fiona_7]

I have purchased my elderly mum a Bush brand sound bar to connect to her Grundig TV. I have the same sound bar connected to my TV via a headphone port and it works just fine for my purposes. Mum's Grundig TV does not have a headphone port. How can I connect the 2?

Could you give us the model of the TV? And preferably the model of the sound bar?
