Jack Errors on starting

Post by Doug B »

I just installed Linux Ubuntu Studio 16.1.

When I try and start Jack with qjackctl, I get the error message:" D-BUS server could not be started." followed by the error log:

14:46:27.996 Statistics reset.
14:46:28.042 ALSA connection change.
14:46:28.156 D-BUS: Service is available (org.jackaudio.service aka jackdbus).
Cannot connect to server socket err = No such file or directory
Cannot connect to server request channel
jack server is not running or cannot be started
JackShmReadWritePtr::~JackShmReadWritePtr - Init not done for 4294967295, skipping unlock
JackShmReadWritePtr::~JackShmReadWritePtr - Init not done for 4294967295, skipping unlock
14:46:28.189 ALSA connection graph change.

Help, please!

Modul name http://www.alsa-project.org/main/index.php/Matrix:Main.

Code: Select all

cat /proc/asound/cards
i have first the "Loopback" device. :(

Code: Select all

 0 [Loopback       ]: Loopback - Loopback
                      Loopback 1
 1 [PST            ]: Digi96 - RME Digi96/8 PST
                      RME Digi96/8 PST at 0x90000000, irq 21

So i edit as root

Code: Select all

nano /etc/modprobe.d/alsa.conf

Code: Select all

options snd-rme96 index=0
options snd-aloop index=1

This is for System/all_USER.

As User edit

Code: Select all

nano  ~/.asoundrc

Code: Select all

defaults.ctl.card 0
defaults.pcm.card 0
defaults.timer.card 0
This is for USER.

Now looks like:

Code: Select all

cat /proc/asound/cards

Code: Select all

 0 [PST            ]: Digi96 - RME Digi96/8 PST
                      RME Digi96/8 PST at 0x90000000, irq 21
 1 [Loopback       ]: Loopback - Loopback
                      Loopback 1
qjackctl/Cadence will now start.
