This could fix it, ggo to my documents->bioware->mass effect 3->Biogame->config folder
move your "gamersettings.ini" to your desktop and reload the game, all your sound settings should be reset (if this doesn't solev the issue you can always return the file to the folder)
you can also try running the configuration tool found in:
programfiles->origin games->mass effect 3->binaries
run "masseffect3config"
hope this helps😕mileyvery-happy:
