This all looks like good news, suggesting that under most conditions people won't notice the difference (except in the signal conditions I saw, in which case they will see a rather significant positive improvement). And since we don't let users independently control the AA filter nor the amplifier, we can be confident that there won't be a case when the amplifier is on but the AA filter is off. My vote is to just push the one line change then flipping on the AA filter in the saa7115_init_misc array of registers (essentially the patch below): http://kernellabs.com/hg/~dheitmueller/em28xx-test/rev/42272c1dd883 Devin -- Devin J.
