If you have additional information or clarifications for your original question, you should edit or comment on the original post. It is not appropriate to keep posting this same question multiple times.

it’s different, my audio controls is not shown even if i’m not add source. and i have reference link

All of which would be appropriate edits or comments on the original post.

Or, you could delete your previous question if it is no longer valid, leaving this one as the open question.

i wish if i can delete it, but the one who can delete the post is moderator

Really? On all posts that I’ve made, if I click on the three-dot icon next to “Reply”, I get a trash can icon allowing me to delete my post.

here’s the message when i click trash icon. i just flag it and wait the moderator, it’s just what i can do

Interesting. Then yes, that along with the reason of “Duplicate post - not needed” - or something to that effect is the appropriate solution.

yeah, can you help me? maybe i was wrong with the urls
