One problem with this - console.perms will overwrite this when the
ownership of the console changes. From
/etc/security/console.perms.d/50-default.perms
<sound>=/dev/dsp* /dev/audio* /dev/midi* \
/dev/mixer* /dev/sequencer* \
/dev/sound/* /dev/beep \
/dev/snd/* /dev/adsp*
and
<console> 0600 <sound> 0600 root
So the permissions will get changed back to 0600 and the owner will
ether be root, or the owner of the console. (The user logged into
the first X secession in this case.)
