iPod Video 5th gen on JBL On Stage II - some remote buttons not working

[ej1287]

Using Rockbox version 3.9.1 (latest stable as of today), although I've already noticed the problem on earlier versions.

Controls on the iPod work fine when docked to JBL On Stage II external speakers. However, the some of the remote control's buttons don't work.

What buttons work as expected:
VolumeUp and VolumeUp long press- increases the volume on the speakers (iPod volume untouched)
VolumeDown and VolumeDown long press - decreases the volume on the speakers (iPod volume untouched)
FastForward long press - forwards playback within the currently playing song
Rewind long press - rewinds playback within the currently playing song

What doesn't:
FastForward - rockbox treats the button as a long press instead of skipping to the next track
Rewind - rockbox treats the button as a long press instead of replaying the song from the beginning
Pause/Play - stops the currently playing song and returns to the main menu instead of staying on the playback screen; slow/no response when resuming playback while at the main menu

There is probably something wrong with the button mappings or perhaps some unimplemented features? I'd be glad to help if you need more data on the problem.

Thank you.

It sounds like this dock uses Apple's accessory protocol.  Rockbox has limited support for this.  Here's a wiki page listing various iPod Accessories.  Feel free to update it with your findings.
