Solved. It was me! I was making links with pw-link -P ... but should have
used -L which I'm sure I tried, but must have failed for some other reason.

Hmm. I went to check something online and there was an embedded youtube
video to see. I clicked on it and thought 'I know that tune!' :-) I had
forgotten that I'd left jack-play (not) playing and linked to the playback.
Paused the video and the music stopped. Un-pause and off it went again.

My QJackCtl Patchbay doesn't work any more and it's obvious there are
new ways to get similar functionality with WirePlumber, but a little
example would help. I seem to want to pipe the output of pw-link -l
somewhere (pw-link -l | wireplumber --make_it_so).

Working wonderfully well now, for me, as far as I've tested on a
hardware limited PC (Intel NUC -> Topping TP30). Amazing to be able to
run VLC into Alsa, PulseAudio or Jack, without changing anything else.
I even tried the OpenBSD output. Firefox audio always just works now.

A timely thread, for me. I've just moved to a faster PC and, with an eye
to getting pipewire working, I've installed VirtualBox (6.1.30) and made
a VM of the same distro (Mint 20.3) as on the host. I'll clone it so it's
easy to 'redo from start' when I mess it up.

Could someone please do a simple test on any Pipewire installation
set up to use/replace Jack (or shed any light on this).
If I run 'pw-record crontest.wav' it works fine, as expected.
If I run 'pw-cat 2> er.txt' ditto, of course.
If I setup a user cronjob with 'crontab -e' to run the command
New problem. I run jack_capture, at certain times, via cron.
Can run the script manually and it works fine, but just doesn't start
from the cronjob. I have no idea why.
Same story with arecord and pw-record (which has no -d duration). Script
works fine from command line, but no joy from the cront

Yes. I've used it for a whole day now, on Linux Mint 20.1 Ulyssa base

Jack_showtime man page doesn't mention any options available and
the problem I have is the frequency of the lines it outputs.
Over 12,000 lines per second according to a little Perl script.

were no complaints when I pasted it in.

I'm convinced Jack transport, using 'carla-bridge-native' and
controlled by jack_transport CLI tool, is the easiest way to go.
I'll use Qprocesses initially and work on using the API later.
QJackCtl sources led me to jack_transport_query and QtCreator
makes it easy to follow the code, so I hope to

I need a command line sound file player which I can somehow control,
while playing, to go immediately to a new position in the same file
and keep playing without missing a beat. And a way to pause/continue.

FOSS developers are so generous that all users are already in

You/they have my admiration, but it doesn't seem enough and the
