jack with realtime
(1/1)
amuctued:
User tc starts jack but Cannot lock down {number removed} byte memory area (Cannot allocate memory), Cannot use real-time scheduling and Operation not permitted
User root starts jack with realtime enabled
Tells me it's a permission issue. Then I read this https://jackaudio.org/faq/linux_rt_config.html where it mentions audio group and setting limits for it
I find this file on my system /etc/security/limits.d/audio.conf.disabled:
--- Code: ---# Provided by the jackd package.
#
# Changes to this file will be preserved.
#
# If you want to enable/disable realtime permissions, run
#
# dpkg-reconfigure -p high jackd
@audio - rtprio 95
@audio - memlock unlimited
#@audio - nice -19
--- End code ---
According to the link above I make a copy of it to /etc/security/limits.d/audio.conf but realtime still won't work for tc (is in the audio group). Do I have to make this file available at boot? Are dpkg* commands supposed to work on dcore?
amuctued:
I've set up a quick devuan vm to test this. In devuan jack did start with realtime under a non root but only with the audio.conf AND after a reboot.
I then tried to make the audio.conf available at boot in dcore, rebooted but no go.
I then tried including alsa-utils and jackd2 at boot, rebooted: no go.
What else can I be missing?
