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> errrrr.txt' ditto, of course.
If I setup a user cronjob with 'crontab -e' to run the commands
(at the start of the next minute or so) the first does nothing,
while the second works.
Cron writes to /var/log/syslog like:
CRON[7694]: (john) CMD (pw-record crontest.wav)
rtkit-daemon[1277]: Supervising 7 threads of 4 processes of 1 users
(second line repeated)
