Despite searches within the wiki and some KDE Plasma forums, a total solution for this problem has not been found.
Changing the profile usually results in editing the sound card output, which can cause loss of the sound card connection.
What I consider strange is not having an alsa folder with those configurations, in a previous installation I remember having it, unless it has been modified through Manjaro.
I had to resort to reinstalling the system since it became a loop of problems constantly reinstalling the mentioned package. It is a moderately new installation since I had to change storage disk recently. Although I personally dislike reinstalling for such simple things.
I even remember doing a How To a long time ago from the same forum, only that without the existence of the folder there is nothing to restore. If anyone has this problem and the folder exists, I would recommend doing what is mentioned in this How To.
