The "+" means there's an acl on the file, in addition to "standard" Unix permissions. As someone else mentioned, logging in on the console is supposed to set up those acl's. Use the getfacl command to read the acls -- for instance, on this system: _[/dev/snd]_(scott@eva)_ $ getfacl hwC0D0 # file: hwC0D0 # owner: root # group: audio user::rw- user:scott:rw- group::rw- mask::rw- other::--- The file reads: crw-rw+ 1 root audio 116, 10 Mar 22 20:22 hwC0D0 Yes, you could also "fix" a perms problem by dropping the user into the audio group -- but then, they will always have access to audio, even if they aren't logged in at the console...which could have security ramifications for multi-user systems. -Scott -- users mailing list users@lists.fedoraproject.org To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?

The most basic is to maximize logging from sound applications. Or you could compile alsa-lib with debugging turned on and trace what happens when sound is sent through it using gdb. Or you could run a sound playing application with strace. In a GUI, most things are event driven, so the paths periodically exist and don't exist.

Pulse is not aware that you have any sound devices. Install the package pavucontrol. Start the app, and go to the last tab. It allows you to manage the devices there. You will probably have to turn them on, and make the correct device the default. > > The audoo card shows up under udev, but pacmd list-cards says that > no cards are available. Any ideas? Again, KDE can output sound, so > the is something (many things:-) that I am missing. Is there any way to tell what sound mechanism KDE is using to play? Try opening a term in KDE and doing the aplay another_brick_in_the_wall_part_2.wav again. Does it play? Was your system a new install, or an upgrade? If it was an install, did you use a KDE live CD to install, or a DVD? Have you installed another low level sound library like OSS4? I ask because this is so unusual.

However, you "force fixed" it and are hiding the underlying problem. When you login the acls of the devices listed in /dev/snd should be changed to something along the lines of: # file: hwC0D0 # owner: root # group: audio user::rw- user:egreshko:rw- group::rw- mask::rw- other::--- In your case that is not happening. So, you've force fixed it by joining the "audio" group as all the devices are in the "audio" group. This could also point to other issues on your system where other acls aren't getting properly modified on login. In any case, it is *not* a "requirement" as you've stated. It is a "kludge" to get around another problem. -- Do not condemn the judgment of another because it differs from your own.
