[PlanetCCRMA] jack - port segment key 0x0

[Mark Knecht]

Fernando,
   This much was working last night. I couldn't play the CDs, but I
could start the app. Today it's dead.

   Has anyone on the Planet seen this error message before?

   I tried removing both the jack and alsaplayer RPMs and reinstalling
them. Still the same error.

   It's a jack error - Ardour ran yesterday and has stopped working
also...

Thanks in advance,
Mark

I could not find a suitable output module on your
system. Make sure they're in "/usr/lib/alsaplayer/output/".
Use the -o parameter to select one.
