FFADO Mixer. Save Scene and Recall Later?

777funk · Post by **777funk** » Wed Mar 12, 2025 11:53 pm

I have hit save and there's a file supposedly saved. But Open doesn't seem to do anything. Is there a trick to load the settings saved previously?

Clicking open should open a file dialog window

It does do that (open dialog is there). But when I open the saved file made previously, it will blink the LED on the unit, however no settings are resurrected.

I just tried it and it crashes the program when I try to load a saved file, so it may well be broken. Try opening the program with a terminal, see if it shows any error messages when you try to load a file.

Interesting. For me it doesn't crash the program. It just flashes the status LED on the M-Audio 2626 (or 610) and loads nothing. But I did find an improvement.

-Save setting (does as expected and creates a file)
-close ffado mixer.
-Power down the interface
-Power up the interface
-pkill ffado-dbus-serv (kill the process in the terminal)
-Load the Saved setting. Nothing happens - the app loads a blank slate (defaults)
-pkill ffado-dbus-serv (kill the process in the terminal) OR just close ffado mixer
-start ffado-mixer
-When it opens the app again, the saved setting is what opens automatically.

When I saw this for the first time, I was thrilled! But... the fun ends there... sort of. It saves all the mixer settings. BUT... the routing is not saved. So I have to go into crossbar router and re-add all the dropdowns for what needs to be in the mixer. But... this is progress. It does work after this. It'd just be nice if it also saved the crossbar router so that everything just worked upon open. Maybe it will get there. These are the settings on the crossbar router that I have to reload to match the mixer (out 1 = LEFT; out 2 = RIGHT). This is for 4 inputs on the interface PLUS a stereo pair sent from the DAW (1394 = firewire audio out from the DAW). Panning is done by faders in the mixer.

And this is what the terminal shows:

I've been working with the FFADO devs on this. It seems that maybe it's an issue with my version (2.4.5 from the software center) and Ubuntu 22.04.

So far I have gotten FFADO 2.4.9 (latest) to install. But not having much luck with things improving. But some progress is happening. After installing 2.4.9, now the crossbar router does not work at all. I do wish there were a compiled and working installer for the Ubuntu versions.

EDIT: all works fine with 2.4.9 crossbar router once installed properly and FFADO has been killed and re-opened.
pkill ffado-dbus-serv

I'm not sure what problem I was having but it was resolved. However this was not the save issue. This fix is noted a few posts further (thanks to FFADO dev Jonathan Woithe).

For your information:
Rob Savoury maintains several Ubuntu PPAs. One of it is called "Multimedia" and offers ffado 2.4.9 already compiled and packaged for several Ubuntu versions. Jammy usually also can be used on Debian 12 systems.

Ok to update this for any other M-Audio user, the problem has been solved here:

To get save/open working, the original libffado-2.4.9 folder (extracted from the zip) needs to have a file edited before building with scons and installing. That file is in this folder (within the extracted libffado-2.4.9 of course):
support/mixer-qt4/ffado/widgets/crossbarrouter.py

In crossbarrouter.py, go to line

Delete the following lines:

Code: Select all

    source = s.split()[1]
    if sources.find(source) != -1:
        idx = self.switchers[destination].combo.findText(source)
        self.switchers[destination].combo.setCurrentIndex(idx)
        self.switchers[destination].comboCurrentChanged(source)

Replace them with this:

Code: Select all

    source = s.split()
    if len(source) > 1:
        source = source[1]
    else:
        source = ""

if source != "" and sources.find(source) != -1:
    idx = self.switchers[destination].combo.findText(source)
    self.switchers[destination].combo.setCurrentIndex(idx)
    self.switchers[destination].comboCurrentChanged(source)
else:
    self.switchers[destination].combo.setCurrentIndex(0)
    self.switchers[destination].comboCurrentChanged(0)

The indent of these should be set so the first line matches the indentation
previously used for line 251 (the "source = s.split()[1]" line).

Make the above change in the

Code: Select all

support/mixer-qt4/ffado/widgets/crossbarrouter.py

file within the libffado-2.4.9 source tree. Then repeat the build and
installation steps from the libffado-2.4.9/ directory:

Code: Select all

scons
sudo scons install

You don't have to uninstall first because you're just reinstalling the same
version (so the new files will simply replace the previously installed ones).

CREDIT Goes to Jonathan Wolthe (one of several devs for FFADO) for helping me find the solution to this problem.
