--- Comment #7 from Alain Kalker <a.c.kalker at gmail.com> ---
One interesting thing found:

$ getfacl /dev/snd/{seq,timer}
getfacl: Removing leading '/' from absolute path names
# file: dev/snd/seq
# owner: root
# group: audio
user::rw-
group::rw-
other::---

# file: dev/snd/timer
# owner: root
# group: audio
user::rw-
user:miki:rw-
group::rw-
mask::rw-
other::---

Yup, that supports my suspicion: the 'timer' device has an entry in /sys, and
so it gets the right ACL set. 'seq' has no entry in /sys, and doesn't get right
ACL set. Bummer.
