Yes, to the best of my knowledge, there were no changes wrt SCO PCM
between GTA01 and GTA02. The same with USB HCI interface. That's why i
was very surprised to see that message from Lorn.

Still it looks like asoc driver for GTA01 will need to be "backported"
from GTA02, but it's a matter of software, so it can be made to work.

Be free, use free ( software!
