Thank you so much Ralf Jung. I did what you suggested and it now works!
Because it is not obvious how to do it, I have recorded below my sequence of steps:
Settings -> Configure K3b -> Plugins -> Audio Encoder -> External Audio Encoder -> Configure -> Mp3 Lame -> Edit
Tick the checkboxes for Swap Byte Order and Write Wave Header in the popup.
Then Apply -> OK twice and you are good to go.
Once more, many thanks for the workaround.
