 |
|
I'm trying to get jack audio to work.
I've traced the problem down to the security subsystem appearing to not read /etc/security/limits.d/40-realtime-base.conf.
Jack is producing this error message when I run it as a regular user:
| Code: | JACK is running in realtime mode, but you are not allowed to use realtime scheduling.
Please check your /etc/security/limits.conf for the following line
and correct/add it if necessary:
@audio - rtprio 99
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! |
I'm pretty sure this is happening because the system is not using /etc/security/limits.d/40-realtime-base.conf which looks like this:
| Code: | # Start of 40-realtime-base.conf from realtime-base-0.1
@realtime - rtprio 99
@realtime - memlock unlimited
# End of 40-realtime-base.conf from realtime-base-0.1 |
I'm not certain what to look at. Does anyone have any experience with this?

Try to copy all relevant changes into the file:
| Code: |
/etc/security/limits.conf
|
and check if it works after this is done.
I can check my system later at home. I had done a working jack configuration but do not know the details by heard.
