Glad to hear. I have no desire to run as root, just that some on line docs
I found seemed to suggest running as root.

Tried several. Currently:
jackd --sync -dalsa -dhw:8
hw:8 is definitely the Multiface. aplay -D plughw:8 plays there just

No such audio driver 'jack'
Could not open/initialize audio device -> no sound.
This is stock rpmfusion build of mplayer 1.1 for Fedora 20 (x86_64). I'm assuming
