Don't we want to compare straight to ALSA to pd to JACK to ALSA, just with Pd running? Having Pulse in the mix is good to measure as well, but I'd like to get a handle on the "JACK adds no latency" statement and comparing additionally with just Pd running through JACK will simplify that.
Also, it may be helpful to add: Pd through JACK, VLC using JACK backend through Jack and compare it to the one using PulseAudio through JACK.
If I'm not mistaken, it was your original idea to test a setup where all audio sources can be played together with Pd, i.e. Pd + PulseAudio + JACK, and compare with Pd's current default routing (plain ALSA). So that's what I did. I'm now eager to know results from others before further delving into it.
Another question: what are you using to play the Youtube video? I know the proprietary Flash plugin caused problems with Pulse at one point.
Flash plugin indeed (no problem with Pulse on Xubuntu). Should we better find an HTML5 stream for the test?
