Is there one such distrib that is not PulseAudio based? (and possibly also without SystemD).

I liked quite a lot Alsa/Jack based audio management, but nowadays it seems more and more implemented over a PulseAudio layer, which I would try to avoid.

My main motivation is that PulseAudio has had latency problems in the past (I don't know what is its status now, but Alsa/Jack never had such problems), but also I'd to avoid to depend on the DBus infrastructure if it is not strictly required (and in the case of audio management there are alternatives, so DBus is not strictly required).
