this general topic keeps comming up ......
Yes, all tv sound is in stereo, including football matches!
Normally 2 channel only. That's fine for everything, including surround sound encoded using older analogue Dolby surround. As on most film soundtracks after 1980, and some programmes (eg Simpsons).
The newer 5.1 soundtrack can be directly transmitted via satellite and cable, but not digital terrestrial due to limited bandwidth.

Premiere is also broadcasting in Dolby 5.1.

yes, but, yes, but, yes but .......
If surround sound info is transmitted at all, it will be on both 2 channel and Dolby 5.1 versions together. With correct decoding, they would sound pretty much the same!

Note that, in the older analogue Dolby surround system .....
The 2 channel stereo was Dolby A encoded, then the surround-sound matrixed (out of phase) info was additionally Dolby B encoded.
The end result is that the film's analogue soundtrack sounds pretty good! Most of the clicks/pops/hiss you used to get on worn film soundtracks are completely inaudible.
The later Dolby SR gives even better noise performance (less hiss).
When Dolby film analogue soundtracks are sent, then the broadcaster has to do all the "A" and "B" analogue decoding, before then sending the result as "straighforward" 2 channel stereo, but with the surround-sound included, for anyone with a suitable decoder (in fact, it's impossible to remove the surround information from analogue film soundtracks!).
Unfortunately, broadcasters do seem to muck this up a lot, by not lining up Dolby levels properly, then putting in noise gates, which completely messes up the "stereo image", and can make speech incomprehensible (less money, fewer tv technicians, worse quality control, etc ........).
