FS#12708 - iPod Nano 2G Swapped Channels

I’ve been using the latest dev builds everyday for iPod Nano 2G and still encountering “Swapped Channels” on Playback (e.g. Left Channel → Right Headphone / Right Channel → Left Headphone).

Used latest build 5785cfb-120625

Me too. I thought it is a phenomenon occurring only in my iPod nano 2G.
I attempted to update to the following latest versions, but LR channels ware still replaced each other.

Stable: 3.10
Dev: b19b250-121031

I’m Japanese and poor at English. I am sorry if wrong.

All iPod have this problem probably, becouse Apple makes revert channels in Audio OUT for their earphones, so if You have Apple earphones, all should play good.
Anyway - I think, make this type of option (for revert channels) cannot be hard for our lovely RockBox programmers :) - I know, that isn’t really priority, but it’ll be really usefull for every iPods user.

I use a d66c167 build, and still waiting for that option.

Using dev rev a6409c8 (2012-12-19) → swapped channels,.. can someone please fix this :/,34667.0.html

I can confirm this is still an issue with the official 3.13 build (

Also, selecting ‘Mono Left’ and ‘Mono Right’ outputs the expected channel, rather than the reverse (as per this comment: ).

That’s what I’d expect from a low-level driver bug or hardware issue. If the hardware I2S is at fault, some well-applied pain and suffering could be applied to find a way to finesse the hardware into always sending the correct channel phase to the DAC.
