I doubt this will help, but I can demonstrate that the control does open
and appear to work on my system.
I'm running Ubuntu Studio 19.10 but am running the generic kernel since
(my guess) the low latency kernel causes problems for my 3ware 9750-4
SATA RAID card. Symptom is very slow disk performance.
Hardware is probably very different from yours, also; a Supermicro dual
quad core 55xx Xeon system with sound through a M-Audio Delta 66 card.
Installation was standard, except that I loaded the generic kernel
(5.3.13-050313-generic) to solve my disk I/O problem.
My only problem is that the "Envy24 Control" utility used to manage the
sound card does not store the profile as earlier version did.
I can start and manipulate the Ubuntu Studio Controls window (didn't try
changing any parameter, effect would be unknown).
I did get a lot of messages when executing the control from a terminal
session; of the following format repeated many times:
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 -1,
skipping unlock
JackShmReadWritePtr::~JackShmReadWritePtr - Init not done for -1,
skipping unlock
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

Hi all,
I recently installed Ubuntu Studio 19-10 on my desktop-PC.
If I try to run ubuntustudio-controls the window 'hangs'.
If I run it via a terminal, I get this:
ko@GX520:~$ ubuntustudio-controls
Cannot read socket fd = 13 err = Success
CheckRes error
JackSocketClientChannel read fail
Cannot open controls client
JackShmReadWritePtr1::~JackShmReadWritePtr1 - Init not done for -1,
skipping unlock
JackShmReadWritePtr::~JackShmReadWritePtr - Init not done for -1,
skipping unlock
JackShmReadWritePtr::~JackShmReadWritePtr - Init not done for -1,
skipping unlock
autojack is running
Cannot read socket fd = 15 err = Success
CheckRes error
JackSocketClientChannel read fail
Cannot open controls client
...
...
(repeated several times)
I hope someone can tell me what this means?
