The above line produces the following: ALSA lib conf.c:1592:(snd_config_load1)_toplevel_:606:27:Unexpected char ALSA lib conf.c:2837:(snd_config_hook_load)/root/.asoundrc may be old or corrupted consider to remove or fix it Character 27 is either the '1' or the newline. The MMAP_COMPLEX note might be relevant to a dead end i reached earlier. Does anyone know whether planetccrma builds jack with this option? jackd --help doesn't mention. i have version jackd 0.100.6. Thanks for the assistance. -geoff
