Lightning dock audio port noisy

[otomo]

I connected the iPhone Lightning dock to my Yamaha AVR V-AUX in with a TRS to RCA L&R adapter and the audio is noisy, ie. full of hissy static-y interference. Should I get a TRRS to RCA L&R adapter instead? Is that what the audio port on the iPhone Lightning dock prefers?
