We really do appreciate you opening this ticket to help improve
Mythbuntu, but it needs to be closed for a number of reasons. The
biggest one is that upstream believes this to be fixed in the latest
version. Could you please verify if this issue still exists in the
latest version?

Please do not let the closing of this ticket dissuade you from opening a
new ticket if this (or any other) problem occurs with the newer
versions.

Title:
  mythfrontend crashes when Upmix to 5.1 enabled and mythmusic started

Status in Mythbuntu, Ubuntu derivative focused upon MythTV:
  Won't Fix

Bug description:
  I have a new nVidia GT 430 which I've configured to use HDMI to my amp
  for both audio and video (using nVidia from x-swats ppa - 270.18, and
