I always use upgrade in terminal, and that will tell me if any packages are held back. After the upgrade has finished loading I will go into synaptic and try each held back package in turn, to see if I can resolve any issues. Mostly just packages wanting to install another package, but sometimes maj...

You will find it in jessie-backports, sorry I am running sid.

I have an amd machine and have the 4.1 rt kernel installed. Could be that the amd pc does not have the meta package installed. Look for the package linux-image-rt-amd64 or just apt-get install it. That should pull in the latest rt kernel. Be aware that the 4.2 kernels have an iommu bug which makes t...

Fantastic!! Totally up to date now.

I've been preparing gcc5 compatible packages today, I think it's all done now but not 100% sure. For users in Ubuntu 15.10 or Debian Testing/Experimental (ie, the unreleased/testing versions), you can add this line to your sources.list: deb http://ppa.launchpad.net/kxstudio-debian/gcc5/ubuntu wily ...

I did a netinstall of debian unstable (sid) but you can do the same with testing (stretch): https://www.debian.org/devel/debian-installer/ added a desktop environment to the base package (xface), and then the kxstudio repos to that. I use the latest liquorix or debian rt kernels. Has been rock solid.

which bridge are you using?
I had some weird sound loops and whatnot using alsa jack plugin, but alsa loop jack is all good.

I think I had to disable the iommu option in my amd board bios to get usb3 working properly. There's a bit of info via google.

Sure.
Your questions should be answered here:

you need to install amd drivers for your new card.

In the terminal type these commands:

sudo apt-get install fglrx-driver

once that has installed type:

sudo amdconfig --initial

then reboot... fingers crossed

mine is pretty much the same and is not a problem for me : FFADO diagnostic utility 2.2.1 ============================ (C) 2008 Pieter Palmers 2009-2010 Arnold Krille === CHECK === Base system... kernel version............ 3.19-5.dmz.1-liquorix-amd64 Preempt (low latency)... True RT patched............

mmm dont know why you get that error, perhaps try with 512 periods so: jackd - dfirewire -r48000 -p512 -n3

You may have to get help on the FFADO users mailing list : http://sourceforge.net/p/ffado/mailman/

Is your device plugged into the computer before you boot?

Btw, 2 things. First I have just checked and the firewire driver drop down list is not populated in my install either (focusrite pro 24), so just try to start jack via Cadence. Second, from kernel 3.19 onwards alsa talks directly to some firewire devices (mostly DICE devices) and bypasses FFADO driv...

so everything there and recognised. What happens when you enter this in a terminal: jackd -dfirewire -r48000 -p256 -n3
