Capabilities was an old hack to get things running as non-root with 2.4.x kernels (and the jackstart suid program). What options are you building jack with? You don't need to / should not enable capabilities. This is what the startup looks like here: ---- $ jackd -v -R -d alsa -d hw getting driver descriptor from /usr/lib/jack/jack_alsa.so getting driver descriptor from /usr/lib/jack/jack_freebob.so getting driver descriptor from /usr/lib/jack/jack_dummy.so jackd 0.102.20 Copyright 2001-2005 Paul Davis and others. jackd comes with ABSOLUTELY NO WARRANTY This is free software, and you are welcome to redistribute it under certain conditions; see the file COPYING for details JACK compiled with System V SHM support. server `default' registered loading driver .. creating alsa driver ... hw|hw|1024|2|48000|0|0|nomon|swmeter|-|32bit configuring for 48000Hz, period = 1024 frames, buffer = 2 periods ALSA: final selected sample format for capture: 32bit little-endian ALSA: use 2 periods for capture ALSA: final selected sample format for playback: 32bit little-endian ALSA: use 2 periods for playback registered builtin port type 32 bit float mono audio registered builtin port type 8 bit raw midi clock source = system clock via gettimeofday new client: alsa_pcm, id = 1 type 1 @ 0x9a997f8 fd = -1 new buffer size 1024 registered port alsa_pcm:capture_1, offset = 4096 registered port alsa_pcm:capture_2, offset = 8192 registered port alsa_pcm:playback_1, offset = 0 registered port alsa_pcm:playback_2, offset = 0 registered port alsa_pcm:playback_3, offset = 0 registered port alsa_pcm:playback_4, offset = 0 registered port alsa_pcm:playback_5, offset = 0 registered port alsa_pcm:playback_6, offset = 0 registered port alsa_pcm:playback_7, offset = 0 registered port alsa_pcm:playback_8, offset = 0 ++ jack_rechain_graph(): client alsa_pcm: internal client, execution_order=0. -- jack_rechain_graph() 22568 waiting for signals load = 0.0281 max usecs: 12.000, spare = 21321.000 load = 0.0586 max usecs: 19.000, spare = 21314.000 jack main caught signal 2 starting server engine shutdown stopping driver unloading driver freeing shared port segments stopping server thread stopping watchdog thread last xrun delay: 0.000 usecs max delay reported by backend: 0.000 usecs freeing engine shared memory max usecs: 19.000, engine deleted no message buffer overruns cleaning up shared memory cleaning up files unregistering server `default' ---- -- Fernando
