I can run all jack audio app I have without any problem with my cheap SBLive. I have no xrun with -p1024 and a few when switching desktop or starting apps with -p512 (which seems to be the normal behaviour with a SBLive). But it seems that there is a preference for SysV shm (this is the default in configure !!) so I was wondering why. Christophe
