Just to share my experience as this is one of the rare edge cases that I have encountered:
Switching from dd-wrt to Merlin's ASUSWRT, I find that it kinda screws with airplay.
When I play a movie, I'd usually select the sound to output to my Airplay speaker on my apple tv. After switching to Merlin's FW, I tried playing a movie and there was interference and distortion in the sound.
I suspect its due to the ethernet connection/port that brought about that problem since the issue went away when connecting the apple tv via wifi. I only use shielded cat5e cables btw. All in all, the problem went away when I switched back to dd-wrt.
I remembered spending a whole Sunday just to figure that out. Also, I'm not sure if its just isolated to Merlin's ASUSWRT since stock ASUSWRT might also be affected(I didn't test).
