Make sure you have sco support in your kernel, as a module
or compiled 
in. Don't forget to load the module..

FYI: I have my share of trouble with SCO audio links so I
have no clue 
what else you can do

Also I'm sure that devices was paired.
I check /var/lib/bluetooth/<BT_ADDR>
And also I can cat > /dev/rfcomm[0|1] which is tty of

One moment. To compile snd-bt-sco modules I need to choose
snd-hwdep
But it doesn't appear on ARM arch. I changed
sound/arm/Kconfig adding "select SND_HWDEP"
