mythfrontend crashes when Upmix to 5.1 enabled and mythmusic started

[farnsy]

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 latest Alsa). If I set Upmix audio to 5.1 and start mythmusic mythfrontend segfaults.

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.
