Jack server cannot be connected as client when opening Rosegarden
 

Hello,

I am running Mandriva2005, and have a slight problem(s), i.e. sound usually works alright apart in Rosegarden. I have downloaded jack as well, if I type jack in a terminal it outputs following:
This is jack 3.0.0 (C) 2003 Arne Zellentin <zarne@users.sf.net>
*debug* global_cf: {}
*debug* user_cf: {}
*debug* argv_cf: {}
*debug* username is xxxx
*debug* hostname is xxxx
*debug* mail is xxxx
*warning* charset has no effect without a char_filter
*debug* multi_mode:0
Traceback (most recent call last):
File "/usr/lib/python2.4/site-packages/jack_functions.py", line 110, in gettoc
exec(jack_helpers.helpers[toc_prog]['toc_fkt'])
File "<string>", line 4, in ?
error: (5, 'Input/output error')
Trouble reading the disk's TOC. If you already ripped the CD, you'll have to
cd into the created directory which is either named after the CD's title
or still called jack-xxxxxxxx (xxxxxxxx is a hex number).

...have not the slightes clue what this all means.

When I type Rosegarden it opens Rosegarden but it gives me an error message with:

there might be a connection, but not quite sure. I have read through all concerning Rosegarden/sound issues but still it does not work properly, i.e. no sound output.

If anyone could help, I would be ever so much grateful.
