You can search the forum there have been several posts where people were having trouble with audio/video because they decided to use something other than pipewire in garuda. Besides you can always just reinstall and pacman will pick the package from local package cache directory and you won't even lose your internet data trying to redownload.
Just remember to reinstall pipewire after removing sndio following the instructions in the post I attached before.
Ps: Don't use octopi or some other GUI to perform these actions use the commands I gave.
