Has melody Quest been removed permanently

Hello,
the other day I was messing around on my laptop ( a dell inspiron 6400, on vista ) trying to install a new headset I had brought, after the installation had finished I went onto sound ( through control panel ) to set the microphone sound levels higher,
when I went onto sound it came up with to devives , one being the headset the other being the speakers, now I dont know how but I think I may have deleted the speakers off my laptop whilst tryin to access the headset.
i now have a small red circle with a white 'x' in it, which to me does not make sence because on other forum it says that this is due to sound driver not working , but mine is working fully on the devi...

Hello,
I tried to archive a photo I posted that was part of a collab. I got an error message and now the post is gone. Not in my feed, archived posts, or recently deleted. Can this be recovered at all?

Hello,
I don't have also the "Edit" icon next to recovery email in the Yahoo mail box. I'm trying to remove recovery email address via your instructions and replace "refresh to review/emails" in the copied link etc. but unfortunately this email is still there.
Also there is an orange vertical mark / line on the left side of this recovery email address, does it means something?
I would be grateful if you could send me another option to remove recovery email address.
I look forward to hearing from you
Regards
