Uz jsem z toho dost zoufalej, nedokazu prinutit jackd, aby pouzival realtime scheduling pod beznym uzivatelem (pod root-em funguje) v debianu testing.

Symptom:

td@td:~$ /bin/jackd -v -dalsa -dhw:0 -r48000 -p256 -n3
jackd 0.118.0

JACK is running in realtime mode, but you are not allowed to use realtime scheduling.
After applying these changes, please re-login in order for them to take effect.
You don't appear to have a sane system configuration. It is very likely that you
encounter xruns. Please apply all the above mentioned changes and start jack again!

Pro binarku plati:

td@td:~$ ls -la `which jackd`
-rwxr-xr-x 1 root root 17384 Nov 21 17:48 /usr/bin/jackd

Pritom jsem ve skupine audio (a i realtime, kterou jsem si zkusil vytvorit):

td@td:~$ groups td
td : td disk dialout cdrom floppy audio video plugdev netdev powerdev nvram realtime

Podle debianiho doporuceni jsem zmenil limity v limits.d:

td@td:~$ cat /etc/security/limits.d/audio.conf
# generated by jackd's postinst.
#
# Do not edit this file by hand, use
#
#    dpkg-reconfigure -p high jackd
#
# instead.
@audio   -  rtprio     99
@audio   -  memlock    unlimited
@audio   -  nice      -19

A restartoval pote (nekolikrat :) pocitac.

Presto si stale nemohu nastavit realtime prioritu, coz je podle me kamen urazu pro jackd:

td@td:~$ ulimit -a
core file size          (blocks, -c) 0
data seg size           (kbytes, -d) unlimited
scheduling priority             (-e) 0

real-time priority              (-r) 0

Uz jsem prolezl vsechna fora na internetu (opravdu :) a nevim co s tim - nedokazal by mi nekdo poradit? Predem diky moc.. ava
