--------------------------------------------+-------------------------------
 My configuration:

 My asound.conf file consists of:

 pcm.!default {
     type plug
     slave.pcm "spdif"
  }

 In my Myth frontend, I have:

 Audio Output - ALSA:Default
 Speakers - 5.1

 Digital Output Device - ALSA:lec958 {AESO 0x02}

 I also have the boxes checked for "Dolby" and "DTS"

 If I try to watch a show recorded by an analog tuner (actually, live
 tv in this log), and I check the box for "upconvert", myth tv
 crashes like so:

 FYI - the mixer errors in this log don't seem to matter - I got rid of
 those by turning off the mixer in the myth configuration, that gets rid of
 the mixer errors.  But myth still crashes if I check the box for
 upconvert.

 If I don't check the box for upconvert, I simply get no sound from an
 audio stream like this:

 2010-03-28 10:36:43.789 AFD: Opened codec 0xa89d8d0, id(MPEG2VIDEO)
 type(Video)

 This used to work fine in myth .22.
