[Fluxus] Noisy output from (gh)

[Chris Targett]

Humm,

Even after
* Blitzing all of Jack's preferences
* Using a buffer size in Fluxus of 2048
* Using the 'dummy' JACK driver to bypass any dodgy audio devices

I'm still getting the same result, everything is jumping around like crazy.
It's as if Fluxus was getting a fed bunch of zeros and then a big
surge of non-zeros to make up for it.

Is there anything else I can try?
