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. If we can't get this working, it would be great if you would open a bugzilla for this and put in all the above answers in order to get it fixed. https://bugzilla.redhat.com/ -- 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?

Perversity! ;-) With my home audio system, I can debug things with a signal generator starting at the speaker and working back to the source until I find where the problem is. Is there a way to do similar debugging with pulse audio and alsa? I would like to inject signals at the sound card, the back if I knew what the input were. It is easier with RCA hacks. USB inputs are still beyond my test set:-) (maybe a USB DVD player?). I'm not completely clear what you want to do here. I think you want to treat a software path like a hardware path. 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. I don't think it is possible to do what you want in the way you mean. -- 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?

SNIP Thanks, don I ran into a similar problem with my FC16 installation of the Xfce re-spin. The solution I finally came up with was to remove pulse audio and just go with ALSA. This was based on running into more than a few posting with that suggestion. When pulse works, it's great. When it doesn't work it just gets in the way.

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.
