I recently decided to take the plunge on my iPod 5G to try rockbox, I've had it forever and the standard Apple software + iTunes is a little lacking, so far I've been really loving the additional features etc but I was having really strange issues that my entire iPod would freeze up and become almost unusable (often I would resort to a forced restart). I tried wiping the drive completely, restoring it in iTunes and then reinstalling Rockbox but to no avail I got the same issue.
It would play the song fine once I skipped to it (always a short pause between switching tracks but its always been like that in the old Apple software), the song will play but the everything else locks up, pressing any of the buttons results in a 10-20sec pause before it responds, scrolling is almost impossible during this time, although as soon as you pause said track (after pressing the play/pause button about 8 times until it finally registers) everything turns silky smooth again... Again this is only happening with certain tracks and I didn't know why?
After a few more days I've now noticed it seems to do it everytime I skip to a track at is 'HE-AAC' encoded, MP3, plain AAC etc work fine.
Is this common knowledge that HE-AAC files don't work very well in rockbox/on a iPod 5G?
Additionally how can I work out what files in my library are 'HE-AAC' as they all still end in just .aac, if I could establish which were this allusive HE-AAC I'd just convert them in a heatbeat but I have 1500 songs and no way to determine which are HE-AAC and which aren't??
Thanks for any help/light shed on this....
