hola
am facing the following problem since a month now :
this issue persists on arch gnome, fedora gnome, silverblue gnome & fedora gnome.
also this :
thunderbird makes this pointless folder which has nothing in it.
if deleted it is back when thunderbird starts.
is this just with me or are others facing theses issues as well?
pardone me if there are any discrepancies with this post.
Is your thunderbird email set up to work on imap or pop3 ?
If you start up thunderbird and create a drastique document to send, but dont send, look in that named folder, does a filé appear ?
I question if its just a tempory folder whilst you work. Does it disappear when you quite thunderbird ?
On your sound question
Are you working on a tower or laptop ?
Using internal speakers or external
Do you have a sound card or using just built into the system.
More details you can give the better we can be in helping you
