Installed SL Multimedia 5.5 and found JACK (essential for low latency audio work) completely inoperable. Attempted to reinstall but to no avail. Unfortunately my LINUX issue-sleuthing ability is limited so beyond reporting this bug I hope that other more capable souls can intervene.
projectm-jack jackd or jack? jack is for ripping see "man jack"
The following is for jack (funny guy in past named his ripper -- jack the ripper --actually not that funny).

## Note: you are not eligible to report bugs in the Debian base when using Sparky, but using the Debian Bug Tracking System is a fantastic skill set to learn.

1. If you are in Sparky 5 and have limited skills - especially in sleuthing bugs - I would strongly recommend going to Sparky 4.
2. (Only if your problem is for JacktheRipper) Install inxi and post "inxi -A" and "inxi" also post "apt-cache show jack" ##Note: to copy from terminal use Ctl-Shift-C
example
paxmark@raunes:~$ inxi -A

If it is due to bug 898075 in jack (the ripper) then "apt upgrade" "apt full-upgrade" (as sudo or root) should fix jack
But probably -
The following is for the low latency system - with jack as part of the name of many components -- i.e like jacks on an audio board.
jackd - special daemon named jack.

.
If it is due to the special low latency jackd environment not working maybe try

You can take the following as harsh or as learning. Your post did not (in my view) report a bug. For me, bug squashing involves bug reporting that gives enough info to aid in the squashing process. We do not know your kernel, whether you are using a special low-latency kernel from elsewhere, etc . In the future, more information.
peace out
peace out.
