Aye, I'm familiar with the lack of recording on the 5g jack socket.
The thing is, recording with the dock connector creates a hiss in the right recording channel, when using rockbox. But not with the Apple firmware.
The difference between the two recording methods is that the apple firmware turns off the headphone monitoring when record is pressed.
Hence, I figure that if I disable the earphone when recording is pressed using rockbox....et voila..... I think the hiss in the right channel will stop.
Just don't know how to do it, cos i'm not a coder.
Thanks
