One missing piece for userspace (PulseAudio etc) to actually be able to use
the jack input devices that ALSA create, is that these devices are
accessible by root only. This patch makes the input device nodes accessible
by the same users that can access the sound card: the current logged in
user, as well as users in the audio group.
One thing I was thinking about, was that the udev-acl rule actually grants
read-write access to the input device node, where probably only read access
is needed. Is this dangerous?
Takashi, wasn't there already something else to use from ALSA than the
artificial input devices?
These input devices are just notification from the sound driver at
jack plugging, so basically it's read-only indeed, and setting the
file permission RO would make sense.
I can't judge more since I haven't seen the patch.
