iPod 5.5G issue with Fiio E1 amp

[StevePod]

I have a Fiio E1 amplifier that I use with my 5.5 generation iPod. All of the functions work when operating the iPod with Apple's OS. With Rockbox, the E1 next/previous track and play/pause buttons quit working. The volume controls still work. Is there a way to get all of the functions to work with Rockbox?

Thanks,
Steve

Sounds like it uses some unsupported version of the apple accessory protocol.  If possible, report your findings here:
