ffado-mixer crashes immediately on invocation with ValueError

[Chris Metzler]

ffado-mixer is unusable for me: it crashes immediately upon any attempt to run, with no output other than the crash traceback.

From FFADO maintainer:

   Bug: ffado-mixer crashes immediately on invocation with ValueError

   Suggestion:
       This is a python error in ffado-mixer. An upgrade to FFADO 2.4.4
       will almost certainly fix this. If not, the OP is encouraged to get
       in touch through the ffado-devel or ffado-user mailing list.

Thank you for taking the time to report this bug and helping to make Ubuntu better. The issue you are reporting is an upstream one and it would be nice if somebody having it could send the bug to the developers of the software by following the instructions at https://wiki.ubuntu.com/Debian/Bugs. If you have done so, please tell us the number of the upstream bug (or the link), so we can add a bugwatch that will inform us about its status. Thanks in advance.

After evaluating this bug, it would be impossible to upgrade the verison of FFADO in Ubuntu 18.04 to a newer version, especially considering it's in the Universe repository which is only supported for 3 years. Closing.
