Hi all .... For the people who can run horgand in ALSA but not in jack .... please re-download, hope the bug is fixed. The problem was allocating memory for XWMHints ... to mask the window icon for transparency ... seems that when jack is running ( in non real time ) libpxm hints var need to be declared as static .... of course I will never understand why :-) Thanks to all Josep _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/mailman/listinfo.cgi/linux-audio-user
