Ffado-mixer, libffado fails with python3.10

codebreaker · 19 February 2022 02:03

I am getting the following error when trying to open the ffado-mixer:

If I fix that issue by editing line 303 of matrixmixer.py to be:

font.setPointSize(int(font.pointSize()/1.5))

then I get the error:

For which the fix is less obvious. I get a similar error (different line) if I then do:

As things stand I now have no way of controlling my firewire soundcards and am thus pretty desperate. Any suggestions?

libffado was recently upgraded to 2.4.5 which is in manjaro unstable. You can try that package by switching branches or waiting till the package hits testing or stable.

Hi!
I’m getting a very similar same error on libffado 2.4.5-1:

Traceback (most recent call last):
  File "/usr/lib/python3.10/site-packages/ffado/panelmanager.py", line 460, in updatePanels

    self.mute_action.setChecked(muted)
TypeError: setChecked(self, bool): argument 1 has unexpected type 'dbus.Double'

Everything is up-to-date on manjaro stable branch, I’m running a RME FF800.
The interface plays audio through headphones even without ffado so the kernel clearly is talking to it just fine.
When I launch ffado, the red “HOST” error light is disabled, the window opens and immediately crashes.
Running ffado-mixer with sudo it won’t connect to the FFADO DBus service.
Can anyone please help me?

also, I switched to pipewire by installing pipewire-manjaro and pipewire-jack, but that works fine

Hi again,
I did it! Apparently the issue is with python 3.10 requiring certain variables being of a certain type.
These were the other errors I encountered while fixing it:

  File "/usr/lib/python3.10/site-packages/ffado/widgets/matrixmixer.py", line 166, in __init__
    self.mute_action.setChecked(muted)

  File "/usr/lib/python3.10/site-packages/ffado/panelmanager.py", line 481, in refreshPanels
    for guid in guids_with_tabs:
RuntimeError: dictionary keys changed during iteration

Until the package gets an official fix, I fixed /usr/lib/python3.10/site-packages/ffado/widgets/matrixmixer.py and uploaded it tohttps://dropmb.com/k9HH7
Feel free to run it through VirusTotal first but it should fix the ffado-mixer crashes.
You’ll need sudo to replace the file.

eviupol · 28 April 2022 07:24

revision 2 of my fixed matrixmixer.py
some changes were not strictly necessary:Dropmb Free File Hosting | matrixmixer.py_rev2_2022-04-28.tar.gz
the ffado-dev mailing list is already working on a proper fix, until then you can use this.
just remove the _rev2 suffix and replace in /usr/lib/python3.10/site-packages/ffado/widgets/
again, you can VirusTotal it before installing

Thank you very much for the efforts!

It works flawless on EndeavourOS too
I hope they will fix it soon on the Upstream.

Works for me too, on manjaro. Thanks very much for the fix!
