Connect a TV to a soundbar or AV receiver with a TOSLink optical cable. It sends multi channel sound as light, so it's immune to electrical interference.
One option at £9.91 inc VAT.
TOSLink optical cables carry digital audio as light, from a TV, games console, Sky box or Blu-ray player to a soundbar, AV receiver or DAC. Remove the protective caps before use and avoid tight bends.
