Hi Mark, Thanks for all the work on the AC3 analog stuff. I've been playing around with ver 5 (I just found version 11 today) and had problems with the decoded data apparently not matching the channel. I've got an Audigy 2 with 5.1 surround and would be glad to test for you. I'm building 11 now to take a look.
