JACK Audio Connection Kit over PulseAudio (jopa)

This program bridges JACK Audio Connection Kit to PulseAudio, but sacrifices audio latency.

Usage

$ make
$ jackd -d dummy -p 1024 &
$ ./jopa &

For fluent playback, it is recommended to set JACK buffer size to no less than 1024 frames/sec.

For better sound quality, it is recommend to set PulseAudio sample format the same as JACK (by default, 48000 Hz, 32-bit float).

Choppy sound

• Make sure realtime scheduling is working.

• Set JACK buffer size to a larger number.

• Change the value of ringbuffer_fragments (in the source code) to a larger number.
