Default Linux and Presonus Firepod

I'm trying to get my Presonus Firepod working on my Linux box. Here are the stats:

Dell Inspiron 660s
Intel Pentium G630 @2.70GHz
4GB RAM
Ubuntu Studio 18.10

I added a Vantec PCIe firewire card. Plugged in the Firepod and the blue light came on (only when using Port 2 on the Firepod).

I tried following these instructions:
https://ubuntuforums.org/showthread.php?t=713695

I fired up Jack, and here are the errors I get:

Code:

Fired up Reaper but no dice.

Any ideas on where I should start?

Thank you!

What command did you fire up jack with? Also, if you just run qjackctrl with no options, do you see your Firepod as a choice on the setup page for interface? I'm no Linux expert, but on my machine I see hw:M2496,0 which is the first of my two M-Audio 2496 cards.

The output you posted shows Connecting to PulseAudio which makes me think it's hooking up to your motherboard audio, but again I'm no Linux expert.

I do not.

Doh, that would make a lot of sense! I'll give it a look tonight after my session and see what's what.

Thank you for the tips!

After installing FFADO and adjusting my Jack settings, all is well. The Firepod works perfectly. This little Dell is turning into a decent system for tracking at our rehearsal space.

Glad you got it working and also glad to know that the Firepod is an interface that is now known to work with REAPER for Linux. My local GC had a used eight channel Firepod for a ridiculously low price about a month ago, but it's gone now.

They are not hard to find, there always seems to be a used one for sale online.

I'm recording at 24/48, and haven't had a hiccup yet.

Veddy cool! How low latency can you go with it reliably?

I record 24/44 and am used to no more than 2.9/5.8ms latency in REAPER for Linux. If I don't use any bridged VST/VSTi plugins, I can run reliably at 1.4/2.9ms.
