I try to save my work by going into the session dropdown menu and selecting save, but then later I discover that the changes I thought I had saved have not been saved! The only solution I can find is creating a new snapshot. Anyone else run into this one?
I’m using Ardour 2, AVLinux 6.0.
Hey jpl. I’m no expert and this is my first post. 
Here goes nothing…
Try run ardour from a terminal and see what it prints when you save.
Make sure you have free space available when saving and that you don’t have any filesystem/harddrive problems.
Hi JPL
Are you sure you have read and write permissions on the drive or folder you are trying to save to? I have no other reports of this issue but you should know there is an updated 2.8.16 package available for AV Linux 6 here:
http://bandshed.net/avlinux6-debs/ardour2/ardour_1-2.8.16+SVN13594avlinux6-1_i386.deb
OR alternatively…
For a fully supported bundled version of the latest Ardour2 you can get it here at ardour.org
