I've been getting this message from JACK since an update as well.<br>
<br>
3:58:19.868 /usr/bin/jackstart -R -dalsa -r48000 -p128 -n2 -D -Chw:0 -Phw:0 -H -M<br>
13:58:19.897 JACK was started with PID=4972 (0x136c).<br>
jackstart: cannot get realtime capabilities, current capabilities are:<br>
=ep cap_setpcap-ep<br>
probably running under a kernel with capabilities disabled,<br>
a suitable kernel would have printed something like "=eip"<br>
back from read, ret = 1 errno == Success<br>
jackstart: could not give capabilities: Operation not permitted<br>
