[PlanetCCRMA] soundcard must be detected via local display before detected via vnc

[Bengt Månsson]

That looked like a good theory but when I checked the files in
/etc/security/console.perms.d/ I find no line with <sound> at all (and no
line with /dev/snd either).
Should I add some lines manually or is the problem somewhere else?
