I have tried a variety of combinations of options trying to get jackd to start under PCBSD 11 but nothing works, I only ever get `Bus error`. My soundcard is working fine but even if I had NO soundcard installed, I should still be able to at least start jackd with the dummy driver but even using the dummy driver as root results in the dreaded `bus error` so I can only conclude its bust. # jackd -v -d dummy jackd 0.124.1 Copyright 2001-2009 Paul Davis, Stephane Letz, Jack O'Quinn, Torben Hohn 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 getting driver descriptor from /usr/local/lib/jack/jack_dummy.so getting driver descriptor from /usr/local/lib/jack/jack_oss.so getting driver descriptor from /usr/local/lib/jack/jack_net.so JACK compiled with System V SHM support. server `default' registered registered builtin port type 32 bit float mono audio registered builtin port type 8 bit raw midi clock source = system clock via clock_gettime loading driver .. start poll on 3 fd's new client: dummy_pcm, uuid = 8589934593 type 1 @ 0x801886000 fd = -1 creating dummy driver ... dummy_pcm|48000|1024|21333|2|2 new buffer size 1024 resizing port buffer segment for type 0, one buffer = 4096 bytes resizing port buffer segment for type 1, one buffer = 2048 bytes registered port system:capture_1, offset = 4096 registered port system:capture_2, offset = 8192 registered port system:playback_1, offset = 0 registered port system:playback_2, offset = 0 ++ jack_sort_graph Bus error jackit-0.124.1_5 Name : jackit Version : 0.124.1_5 Installed on : Thu Mar 3 21:15:22 2016 GMT Origin : audio/jack Architecture : freebsd:11:x86:64 Prefix : /usr/local Categories : audio Licenses : LGPL21 and GPLv2 Maintainer : multimedia@FreeBSD.org WWW : http://jackaudio.org/ Comment : Low latency audio server Options : ALSA : off DOXYGEN : off READLINE : on Shared Libs required: libcelt0.so.2 libreadline.so.6 libdb-5.3.so.0 libsndfile.so.1 libsamplerate.so.0 Shared Libs provided: libjack.so.0 libjackserver.so.0 Annotations : icon : \"http://www.pcbsd.org/appcafe/icons/audio_jack.png\" Flat size : 866KiB Description : JACK is a low latency audio server, written for POSIX-conformant operating systems. It can connect a number of different applications to an audio device, as well as allowing them to share audio between themselves. Its clients can run in their own processes (i.e. as normal applications), or can they can run within the JACK server (i.e. as a "plugin"). JACK was designed from the ground up for professional audio work, and its design focuses on two key areas: synchronous execution of all clients, and low latency operation. WWW: http://jackaudio.org/
jackd v1.0 works fine under 9-stable userspace with 11-current kernel, so the problem is likely something in userspace. Can you get the backtrace of the crash from corefile using gdb?
Sorry about the late response. Your replies got filtered into my junk folder unfortunately. I'll try and get a bt for you soon.

Hmmm, that prob wasn't much use was it? Looks like I need to rebuild jack with debug enabled.

I am also having this issue. If I can provide anything to help fix it please let me know.
(In reply to Dan MacDonald from comment #0) I had the same issue with some FreeBSD11-CURRENT version. However the issue seems to be gone now in FreeBSD11-RELEASE. Jack works for me again, for whatever reason!

Does your audio device support both recording and playback. Else try only using on of -C and -P options. --HPS
>>Does your audio device support both recording and playback. Else try only using on of >>-C and -P options. I'm sorry. I don't know device. I use nvidia HDMI. but I use logicool headphone , works fine. Thank you very much! Do you know device (nvidia,HDMI) how to use? cat /dev/sndstat Installed devices: pcm0: <NVIDIA (0x0016) (HDMI/DP 8ch)> (play) pcm1: <NVIDIA (0x0016) (HDMI/DP 8ch)> (play) default pcm2: <NVIDIA (0x0016) (HDMI/DP 8ch)> (play) pcm3: <NVIDIA (0x0016) (HDMI/DP 8ch)> (play) pcm4: <Realtek ALC887 (Rear Analog 7.1/2.0)> (play/rec) pcm5: <Realtek ALC887 (Front Analog)> (play/rec) pcm6: <Realtek ALC887 (Rear Digital)> (play) pcm7: <Realtek ALC887 (Onboard Digital)> (play) pcm8: <Intel Cougar Point (HDMI/DP 8ch)> (play) pcm9: <USB audio> (play/rec) No devices installed from userspace.
I think you need to specify an argument to jackd that it will not try to record from the HDMI connection, and then it will work. --HPS
jack is still not working for me, under HEAD (FBSD12). Even the dummy driver still gives me a bus error.
It looks like this could just be an issue with jack 0.124.1. I have just built jack 0.125 from ports under TrueOS and I can start JACK now.
If this is still an issue, it works for me with arguments: > -r -doss -r44100 -p1024 -n3 -w16 --capture /dev/dsp6 --playback /dev/dsp2 Otherwise, /var/log/jackd.log has an error log.
