I decided to instead make this link 32bit, byusing 2 16bit channels, thus resulting in 16/2 = 8 channels.I do have one datasheet that hints at a 24bit channel from emu10k2 andthe PCI bus, but I have not checked if the 1212m version of the emu10k2supports it. It might only be the 1616m that supports it, and I have notadded support for that in alsa yet.
