Hi, I am aware of the CAP_SINGLE problem and will try to work on it this weekend. Try playing around with the driver since you have the databook. I find that in problems like this printing the status registers in bktr_intr helps a lot. As for the audio stuff I have not played with it yet. All in all I will back working on the Bt848 stuff this weekend because I am currently behind on my contract.
