So I have tried using JACK regularly with the PulseAudio to JACK
bridge. Unfortunately this has some quirks too. JACK won't start
unless I wait several seconds after plugging in the Ultralite AVB. I
I've seen this and I just live with it. I change SR once in a blue
moon. It just isn't that important to me. I suspect it really does
that the MOTU unit a long time to reset to a new SR. JACK will start
eventually.
I don't want to change sample rate either, but the device's sample rate
changes when I don't want it to. When it starts up it defaults to 192
kHz and there's also that quirkiness with PulseAudio trying to change
the sample rate. Perhaps I could ask MOTU to have it set the same rate
on startup to what it was on the last shutdown in a firmware update.
That seems like it would be pretty easy for them to implement
considering it has some persistent storage onboard.
Even when the Ultralite AVB is set to the same sample rate as JACK, I
have to wait ~10-15 seconds after plugging in the Ultralite AVB before
starting JACK works. This seems like an issue with Linux or JACK rather
than the Ultralite AVB. Anyone have an idea what's going on with that?
Has anyone contacted MOTU about the sample rate switching issue?
Ideally they could make it just work when the computer tells the
audio interface to switch sample rates.
Also, has anyone contacted them about possibly changing the firmware
so the web interface is available over USB on Linux?
if you have an AVB unit, why bother with USB? My impression (which
could be wrong) was that it would work if you have the correct kernel
module loaded. I don't know which module that is.
Do you mean why bother with the web interface over USB? So I don't need
a router to use the web interface at a gig. At home it's no problem to
leave an Ethernet cable plugged in. I've tried plugging an Ethernet
cable directly from the Ultralite AVB to my laptop but that doesn't
work. I'm getting a new laptop soon and new laptops generally don't have
space for RJ45 jacks anymore, so that wouldn't be an option.
Plus, the MOTU Ultralite Mk4 doesn't have an Ethernet port so its web
interface is only accessible over USB.
