--- Comment #16 from Anssi Hannula anssi@mageia.org --- It seems to be https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=7... + the fact streams are assigned in reverse order.
I'll have a patch for reversing the assignment shortly.
Alex, is the limit 4 streams on 7-output cards as well, or is it just these 1-output cards only?
