Re: Ultralite AVB

I downgraded to the suggested v1.1.4+923 firmware and I'm not getting any channel skipping. What issue I did run into was I have a monome 512 which runs over a USB2 connection (running from a hub using 2 FTDI serial converters) and was getting interference in the USB bus of my single board computer....

Re: Ultralite AVB

Alright, this seems to be working with a pretty large buffer (2048 samples, 6 periods) at 24/96; I've patched six channels of outputs to inputs in the analog domain, and configured my DAW to thread a tone through out/in/out/in ... with six OI pairs.

Re: Ultralite AVB

I did some research today with the 1.3.4-xxx firmware and created a patch (against linux-4.19.5). - Changing the sample rate will still take about 10 seconds to complete due to the interface completely reorganizing internally. So, if you are using jack, set the timeout value to 10 seconds. - In cas...
