I'm starting jack via jackstart like this: jackstart -v -R -d alsa -d ice1712 -r 44100 -p 64 -n 2 I can run ecasound in many ways (different chain settups, via ecaplay, wav or ogg input, etc.) one time only. If I try to run another ecasound session without restarting jack the second ecasound exits like this: audiobox:~$ ecaplay /mnt/audio/in_progress/guitar_mix/s2004-0217-2242.ogg *********************************************************************** * Message from libecasoundc: * * 'ECASOUND' environment variable not set. Using the default value * value 'ECASOUND=ecasound'. *********************************************************************** (ecaplay) Playing file '/mnt/audio/in_progress/guitar_mix/s2004-0217-2242.ogg'. exiting... It doesn't return ... just hangs like that until I ctrl-c it. If I strace the ecaplay it's waiting for ecasound: audiobox:~# strace -p 450 Process 450 attached - interrupt to quit waitpid(451, <unfinished ...> Process 450 detached which is stuck in a futex(): audiobox:~# strace -p 451 Process 451 attached - interrupt to quit futex(0x413e6bf8, FUTEX_WAIT, 453, NULL Once I kill the ecaplay w/ctrl-c the "ecasound -c -D" remains until I use kill -9 on it. Anything else I can do to help debug this? System details below.
