Is JACK supported?

Hello,

Wikipedia states Ring's features include Jack Audio Connection Kit support. PulseAudio introduces additional latency which then results in sporadic buffer under/over runs ('xruns'). All I can see is the option for ALSA or PulseAudio for the audio manager's options.

I am using KXStudio's ALSA -> PulseAudio -> JACK (Plugin) bridge type via its Cadence application for non-JACK aware applications (eg: Google Chrome). SMPlayer & DeaDBeef audio player (w/ the JACK output plugin) has no issue connecting to JACK.

I was under the expectation it would be possible to create a source/sinks similar to how SMPlayer can be set up to use JACK. How one can use JACK w/ Ring?

Please advise if I can provide any further details. TIA.

(EDIT: added details about OS, PulseAudio usage & versions, JACK & PA apps in use.)
