Now that the audio cape works (when it's the only thing in the
stack...) I'm trying to get it and the DVI-D cape working together.
when I place the DVI-D cape on the stack the audio players (aplay,
timidity, mpg123, etc appear to play just fine but no audio is output
through the headphones and the audio cape is *NOT* shown when I "cat
/sys/devices/bone_capemgr.8/slots". here's some commands and outpu
tbelow:
any idea what the problem could be?
Thanks,
Eric
