[SOLVED] Jack on crouton

Post by jrood »

Here's the trouble: When I try jack_control start i get

Code: Select all

DBus exception: org.jackaudio.Error.Generic: Failed to open server
Possibly relevant info:
I'm running ubuntu wily via crouton on a chromebook pixel 2015.
I have jack2 installed.
I have verified that i am in the following groups: hwaudio video sudo plugdev audio input
I've verified that cras is stopped (so as not to interfere).

my ~/.asoundrc looks like this

Code: Select all

pcm.!default { 
    type hw
    card bdwrt5677
}

ctl.!default { 
    type hw
    card bdwrt5677
}
the output of ulimit -r -l is

Code: Select all

real-time priority              (-r) 95
max locked memory       (kbytes, -l) unlimited

you should start jack with this command, if not try to provide output of all commands.

Code: Select all

jackd -P60 -dalsa -dhw:bdwrt5677 -r44100 -p1024 -n2 -P 

Code: Select all

aplay -l
sudo lsof | grep /dev/snd

I tried to launch jack that way before, but maybe i just didn't try that exact set of parameters.
