FULL STEPS:

1. Go to /admin/settings.php?section=mod_bigbluebuttonbn_showrecordings and find bigbluebuttonbn_recordings_sortorder to confirm that "Order the recordings in ascending order." is unticked
2. Go to a BigBlueButton activity (/mod/bigbluebuttonbn/view.php?id=xxx) that has recordings showing.
3. Observe the order of recordings.
4. Go back to step 1, and tick the box.
5. Go back to the activity in step 2.
6. Observe the order of recordings.

WHAT YOU EXPECTED:

Step 3- I would expect the recordings to be ordered in descending order, as per the settings page description.

Step 6- I would expect the recordings to be now ordered in ascending order, as per the settings page description.

WHAT ACTUALLY HAPPENS:

Step 3- The recordings are ordered in ascending order (despite settings page having ascending order unticked).

Step 6- The recordings are ordered in ascending order (looks like the setting has no affect).
