[mythtv-users] Audio static when playing mp4/mkv files on 24.1

I'm having problems playing mp4/mkv files on 24.1 They are being played
through a NVidia HDMI output to the TV. All other files/recording play
fine, and the mp4/mkv files play fine when played with mplayer and alsa,
but when played with the Internal mythvideo player only static noise is
heard

Mplayer shows:

Playing
/storage/Videos/HARRY_POTTER_SERIES/HARRY_POTTER_SORCERER'S_STONE_EXT_2001_BluRay_1080p_QEBS_AAC_PS3_MP4-FASM.mp4.
libavformat file format detected.
[lavf] stream 0: video (h264), -vid 0
[lavf] stream 1: audio (aac), -aid 0, -alang eng
VIDEO:  [H264]  1920x800  24bpp  23.976 fps  2234.2 kbps (272.7 kbyte/s)
Clip info:
 major_brand: isom
 minor_version: 1

mythfrontend log shows:
ALSA, Error: failed to register mixer device default (or anything else
entered on the SETUP/GENERAL/Mixer field)

/proc/asound/cards:
cat /proc/asound/cards
 0 [Intel          ]: HDA-Intel - HDA Intel
                      HDA Intel at 0x97220000 irq 47
 1 [NVidia         ]: HDA-Intel - HDA NVidia
                      HDA NVidia at 0x97000000 irq 17

and mplayer -ao file works... as does mplayer alsa:default, or mplayer
alsa:hw:1.3 but none of these work in mythvideo

amixer -c 1 works
and the asound.conf looks like this:
pcm.!default  {
   card 1
   device 3
   type plug
   slave {
      pcm "plughw:1,7"
#      rate 48000
   }
}

ctl.!default {
   type plug
   card 1
   device 3
}

Of course, I can't use mplayer since the files are stored on a Videos
Storage group and the frontend can't parse the filename to mplayer
Any ideas?
