The realtime-privileges package provides the realtime system group, which is permitted elevated rtprio and unlimited memlock with a sysctl drop-in configuration file and is permitted to alter the system's /dev/cpu_dma_latency file, which may be used by applications to prevent the CPU to use higher C states. Realtime scheduling and additional resourcesĪll JACK implementations may make use of elevated realtime scheduling priority, which allows them to make use of the CPU cycles more often than other applications (see e.g. 1024 for testing the waters and lower as much as possible. Start with a reasonably high frames per period value of e.g. Note: Depending on hardware and system configuration, a very low latency may lead to audio dropouts (aka. When looking at jackd(1) § ALSA_BACKEND_OPTIONS as an example, these parameters are defined by the -p and -r flags (respectively). how much time is spent processing one block of audio) is defined by its frames per period/ sample rate ratio. The latency of a running JACK instance (i.e. For 32-bit application support, also install the lib32-jack AUR, lib32-jack2 or lib32-pipewire-jack package (respectively) from the multilib repository.įor the official JACK example-clients and tools install jack-example-tools.įor an alternative ALSA MIDI support in jack2 install a2jmidid.įor dbus support with jack2 install jack2-dbus.ĭepending on your use-case and hardware, the system may need further configuration, to allow a JACK implementation to use additional resources or to function properly. For an overview, refer to #Comparison of JACK implementations. There are three different implementations of the JACK API: jack AUR, jack2 and pipewire-jack. 7.5.1 VLC - no audio after starting JACK. ![]() 7.5 Problems with specific applications.7.3 "ALSA: cannot set channel count to 1 for capture" error in logs.7.1 "Cannot lock down memory area (Cannot allocate memory)" message on startup.6.3.1 Details of the shell-based example setup.6.1 Applications for interacting with JACK and its audio graph.2.3 Realtime kernel and advanced modifications.2.2 Realtime scheduling and additional resources.
