i really don't know what's going wrong on yours, sorry
just tried and tested to add `qjackctl --start` command as an auto-started application in a XFCE session and all seems to be working alright (here using openSUSE Tumbleweed) -- the system-tray icon is enabled and shows up alright in the XFCE notification area, as it should.
