I found this in the history of the linux-audio-user@lists.linuxaudio.org list regarding Jack setup:

Assuming you are using Fedora's jack (see above), please remove the lines you added from limits.conf. Then make sure that your username is in the jackuser group, and in the pulse-rt group (even if you don't use pulse this setting won't hurt).

You can add your user to these groups by manually editing /etc/group and adding your username next to these groups, or by running the system-config-users GUI application and adding the groups to your username.

Then log-out, log back in or reboot. Now you should have a properly running jack.

This information is also in the /usr/share/doc/jack-audio-connection-kit-0.118.0/README.Fedora file.  Check that file out to see if there is anything else you are missing.


Hope it helps, if you decide to go with Jack

Have you tried using Jack at all? If so, can you send us your Jack

Is this list still active?

I've been unsuccessful in different attempts to route playback from
soundcard to an output file (preferably WAV format).  I have tried
arecord, sox etc.

Could someone guide me through this process?
