Title:
  ffado-mixer-qt4 needs an upgrade from 2.4.6 to 2.4.7

Status in libffado package in Ubuntu:
  New

Bug description:
  ffado-mixer-qt4 is a separate package based upon libffado.

  the package and libffado-2.4.6 needs to be upgraded to libffado-2.4.7
  in Ubuntu 22.10

  libffado-2.4.6 contains an error that is fixed in libffado-2.4.7 which
  is described at http://ffado.org/posts/ffado-2.4.7-release/ .
  Specially, the issue is 2.4.7 addresses "additional type-related
  issues encounted in ffado-mixer when using python 3.10. Components
  affected were the crossbar router and the M-Audio device mixer."

  The issue is enough to crash ffado-mixer-qt4 in Ubuntu 22.10. I
  understand from a support discussion, that the fix is even implemented
  in 23.04 (out in about a month). So in principle, I think it should be
  easy to fix.

  As far as ffado-mixer-qt4 is concerned, the issue is a very tiny fix.
  Literally two values are wrapped in int() in 2.4.7 see:
