[ubuntu-mono] [Bug 751575] Re: banshee no longer plays music gstreamer resource error NotFound

Tue Apr 29 20:17:48 UTC 2014

It's still not a bug, just a difference between what newer Linux users
may expect and normal Ubuntu behavior.

When I posted in 2011 I was still new to using Linux on a system with
multiple hard drives, though I had used it for longer on a single-drive
system.  Ubuntu, and Linux distros in general, are never going to auto-
mount hard drives by default.  The fact that Windows does so is an
interesting difference (which wastes a lot of electricity) but it should
not influence the Linux world.

The apparent banshee bug filed here has a simple explanation: the
drive(s) containing the music in your banshee library must be mounted
before you try to play your music.  When people (including myself)
noticed that re-scanning the library appeared to fix the problem, that
was only true because they actually had to mount the drives before they
scanned the library.  And they perhaps did not notice that the drives
became mounted as a necessary side-effect of going to look at them
manually in their file manager.

Regardless of my innocence in 2011, I think it's clear that it's not
banshee's problem if you want to play music located on a drive that is
currently not mounted.  Mounting and unmounting drives is an subject
whose primary issues are power conservation and connection or
disconnection from resources, allowing the facts of whether those
resources are local or remote to be nicely abstracted over.  That
subject has nothing at all to do with a music player, which is only one
of endless programs which may need to access content on a drive.

If banshee were to add the behavior of mounting drives when we go to
play music from them, it would not be responsible to leave them mounted
once banshee was closed, but it also would be wrong to unmount them on
closing banshee because other applications may be using them.  So there
again these are two issues at right angles to each other.

@michaelchirico4: Even easier (for some at least) than one line in the
terminal -- just open nautilus or whichever file manager you use and
you'll see your drives listed in its left column.  A single click on
each one that you want to mount should get it going.  The only waste of
time or space with this is that you then have a file manager window open
that you may not have needed.  But the drive(s) will stay mounted if you
close that window, or you can just minimize it based on the assumption
that you might end up needing a file manager view during your session.

Even simpler than that is that Ubuntu can show your drives in the
launcher so you can mount them from there.  Unfortunately as of 14.04
there is no right-click option to mount a drive, so you just click it
and this still opens a file manager window, but it does accomplish the
mounting so that's one click less.  Ideally the launcher view of drives
would by default show (visually) their mount status and have a right-
click option to mount.

  I can no longer play locally stored music in Banshee.  I get no error
  in Banshee but if I start banshee from the command line I get the
  following error when trying to play a song:
