(Recording can be replayed a thousand times, but play only happens once. The more permanent product should get the benefit of quality.) : 4. define a new ioctl to chose which channel gets the 16-bit dma and : which one gets the 8-bit dma, with some default camong those : described before. This is 2 with sprinkles, and sprinkles are nice, if you can afford the extra dime.
