General

Bugs and more

We tried our best to find and close all remaining bugs for this JAD 1.0 final release.

But like always, you never know, there's still a chance that bugs can show up. If you find any, please help us tracking those down, and report them back to us. You can visit the forum or our irc channel, but using the bugtracker for this is a big advantage -> http://bugs.jacklab.net

Collecting bugs and FRs (feature requests) helps development, because only if we know what goes wrong or what is missing, we can change or append it. With each fixed bug JAD gets more user friendly.

We happily await your feedback.

Installation Media

The Software Management Tool: Smart

  • Smart is recommended as JAD Update Package Manager. PackMan and some other repositories are pre-configured.
  • YaST and zypper are also still available for those who wish to use them.

Updated Wine / with WineAsio

WineAsio is a compatibility layer for Windows (R) audio applications providing low latency ASIO ports for jack. It works really good, especially with "Reaper" http://reaper.fm/ and "energyXT2" http://www.energy-xt.com as VST hosts, with most of the recent VST FX/I w32.dll's.

The favorites menu in e17

We have integrated a favorites e17 menu which organizes the multimedia section. For a better integration of the kdesu configuration tools we have copied some desktop entries from the SUSE (applications) menu. The favorites menu xml source code can be found in .e/applications/menu/favorites of your /home directory and follows the xdg freedesktop standards.

Technical

The RealTime Kernel

The JackLab realtime kernel is installed as default for optimal realtime audio performance. The kernel-rt package contains the rt kernel for both uniprocessor and multiprocessor systems. The kernel comes with SMP support and runs with only minimal overhead on uniprocessor systems. There is no kernel-smp package anymore.

In some cases, specially with an ICE1712 chipset based audio device the kernel-rt can have a very bad performance (lot of x-runs, but more x-delays). There is maybe a relation to network devices letting the performance break in, but this is not sure. Please report your experience to the JAD Team in irc.freenode.net #jacklab.

USB Audio Devices

Users reported bad JACK performance with USB Audio Devices with the current RT Kernel. Please use a PCI audio device if possible for better audio performance.

The Standard Kernel

The kernel-default package is available on the JAD DVD if required. The kernel-default package contains the standard kernel for both uniprocessor and multiprocessor systems. The kernel comes with SMP support and runs with only minimal overhead on uniprocessor systems. There is no kernel-smp package anymore.
