Description john.frankish 2016-01-19 10:22:40 UTC

Using udesks-2.1.6, gvfs-1.26.2, libatasmart-0.19

It seems like udisks does not pass gvfs enough information to know that /dev/sr0 is a cd/dvd and gvfs-mount fails - see https://bugzilla.gnome.org/show_bug.cgi?id=759952

$ gvfs-mount cdda://sr0
Error mounting location: volume doesn't implement mount

gst-launch-1.0 and xmms will both play audio cds from /dev/sr0

Are there any udisks/udev tests I can try to further debug this?

More details below;
