Thanks for the reply. My reason for running via sudo in the first
place goes back to a specific recommendation made to me some
time ago by ...:
You should absolutely run darkice as root. It needs POSIX
real-time scheduling and that should not interfere with anything
else.
This was probably written way more than a decade or two ago or based on
something that old; The limit can be lifted for ordinary users since
ages - see eg.
http://jackaudio.org/faq/linux_rt_config.html
Home directory /home/zidane not ours.
Of course: The process runs as a different user, yet in most of your
environment; try "sudo env" to see it. You might have to tell sudo to
change that, eg. sudo -i
and renice it by -20 if I get any audio skips or dropouts.
IIRC ordinary users can only increase niceness.
PS: Something like darkice can - IMO - hardly push current hardware
(including raspberry pi on an otherwise idle system) in a way to require
realtime efforts.
