add (#)dtparam=audio=on to config.txt for Rpi4

    Hi all, I had tried a reinstall yesterday with several LE versions and almost despaired at the missing audio because I did not realize that I first had to add dtparam=audio=on to Config.txt. This line was also not present to uncomment, so I assumed a defect for a few hours. After all, I've been using LE for a few PI generations, and audio has never had to be enabled like this - and how would I even know I had to enable it first?

    In case of problems I always look in the config, it would be great if you could add this line there in the PI4 versions. For the IR-GPIO pins it is also done, so why not for audio?

    It was already discussed here in past. Unfortunately developers decided to remove this parameter from config.txt in recent LE builds and their argument was a bad quality of the audio output.

    yes, I then searched through about 15-20 posts here to come up with the solution in the end.

    Not every device needs the best audio quality, and with the setup that I revised yesterday, the audio jack is perfectly sufficient.

    My concern is mainly to avoid such situations in the future by keeping this information in the config for us users.
