It is interesting to see, that in DE there are not so many complaints, posts and threads about this issue, but here in EN forums. I was so "glad" somehow to see this thread, because I (and my husband) seemed to be the only ones with THIS issue.

Since Day One of Endwalker I cannot play anymore, because I do not want to ruin my Game Experience and I do not want to mute everything.

I have not even started the Main Story, I do not know how all the content is, I only took Sage and Reaper and am leveling them a bit.

I noticed the issue with the very first (Reaper Job) Quests, and because the sound is so annoying and disturbing I never continued any Quest at all.

I tried everything suggested here and really nothing helped
