I don't know if this is the problem, but it looks like it.
The problem seems to be:
"jackd" needs to run by the same user as the clients.
(At least that's how it was in the old days, but maybe something
has changed since then).
E.g. If the process owner of jackd is root, you can't run jack_capture
as a normal user.
I'm also pretty sure you can run several jackd simultaneously
on the same machine as long as each jackd is run by a different user.

Hey!
Using the jack audio toolkit with my pisound DAC on a Raspberry Pi 3 which was a hassle -
but I got it running with some hacks.
Now for convenience I added jackd and jack_connect (to route input to output) as a
service inside systemd - which works as expected. Before I could easily start jack_capture
to record the input. But now it’s not starting anymore unfortunately. I get this error:
jack_capture -c 5 -mb -tm -f flac
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
>> jack_client_open() failed, status = 0x11
I copied jack_capture also to /usr/locale/bin
My systemd service files:
jack-connect.service —> starts also jackd.service

Can anyone help me with this?
Kind regards
