It appears that apparmor is preventing Gnu Octave from connecting to the Pulse audio pipe. How can I remove this restriction.

dmesg output

[10986.689501] audit: type=1400 audit(1590956219.198:4342): apparmor="DENIED" operation="open" profile="snap.octave.octave" name="/etc/pulse/client.conf" pid=16325 comm="QThread" requested_mask="r" denied_mask="r" fsuid=1000 ouid=0

  • First list the connections via "snap connections " and see what slot refers to the pulse audio . ( Sorry I cannot test that) . and then use snap connect . Something like this : "snap connect octave:pulseaudio :pulseaudio"
