 I've finally seen the pattern to a bug I've been having for weeks - If I'm
 using the qi bootloader (Thanks Andy, so far it's damned promising) then
 sound doesn't work.  I try aplay from terminal and get errors that sound
 device doesn't exist.  Reflash just bootloader back to uboot and sound
 returns.  Reflash to qi and sound fails.

 Both aplay amd mplayer report the following (this is mplayer's formatting,
 same messages from aplay):

 [AO_ALSA] alsa-lib: confmisc.c:768:(parse_card) cannot find card '0'
 [AO_ALSA] alsa-lib: conf.c:3510:(_snd_config_evaluate) function

 dmesg under qi includes:

 ALSA device list:

 While under uboot there's a slight difference with:

 19:16:42 2007 UTC).
 ASoC version 0.13.1
