Hi *, I observed some strange behavior of libjack and libjackserver. If I have a multiprocessing application with one jack server fork and one jack client fork, jack_client_open crashs. Here the backtrace: #0  __strcmp_ssse3 () at ../sysdeps/x86_64/multiarch/../strcmp.S:174 #1  0x00007f83dddb803f in jack_find_driver_descriptor(_JSList*, char const*) () from /usr/local/lib/libjackserver.so.0 #2  0x00007f83dddb9ef8 in Jack::JackServerGlobals::Init() () from /usr/local/lib/libjackserver.so.0 #3  0x00007f83dddb64f8 in jack_client_open_aux(char const*, JackOptions, JackStatus*, __va_list_tag*) () from /usr/local/lib/libjackserver.so.0 #4  0x00007f83dddb67b1 in jack_client_open () from /usr/local/lib/libjackserver.so.0 #5  0x0000000000414f04 in talker_Process (arguments=0x63f680 <arguments>) at ../src/net/avb/talker/talker_process.c:395 #6  0x000000000042d487 in avbruntime (arguments=0x63f680 <arguments>) at ../src/avbruntime.c:644 #7  0x000000000042e888 in main (argc=11, argv=0x7ffebee6f678) at ../src/main.c:144 The interesting thing is, jack_client_open keeps crashing if I remove all the jack server code. It was neccessary to remove the -ljackserver linker option as well, because the client code linked against libjackserver.so instead of libjack.so. This means it is not possible to have a jack server and a jack client in a single multiprocessing application.
