Thanks Ravi, I think the warning is a red herring though, it just
happens to print stdout/stderr only on failure. Those warnings are also
here on success run

Doing some local testing in an autopkgtest and printing the output "out
= self.get_monitor_output()" in test_media_player(()

in a success

the same device is first set up in test_cdrom_api() so it looks like
sometime the volume is removed between the previous test and this one
and sometime not, which then leads to a "changed" event rather than an
"added" one.

A real fix would be to ensure that volume is removed/unsure why it is
sometime and sometime not. Adding a sleep() before "dev =
self.create_host(PTYPE_DISK)" doesn't workaround it.

A potential workaround could be to use a different device name/image for
the cdrom and media cases avoiding relying on the volume to go away in
between tests?
