I'd like to run up to nine soundcards with Jack.

Eight times Expert Sleepers ES-8 via USB
and one RME Madi HDSPe card on a PCIe slot.

In Linux at 96 kilobauds.

I read here
about clocking issues as each card is run by it's own clock.

Will the asynchronously clocked streams be handled and merged by Jack or is this an ongoing issue?

I imagine, if I'd feed analog outputs of one card into the analog inputs of another, this wouldn't be ideal.
But I am wondering if Jack is handling the asynchronous streams in the software-domain without glitches ect. ?

With a powerful computer is the latency going to rise absurdly high? Any experience with this?

As Jack-Devel-List is dead, I'm asking here.

With best regards,
