I installed the latest Rockbox firmware. Ipod would not play many of the lossless files.
FLAC - periodic scratchy hissing noise instead of music. Some files are OK.
APE - every few seconds music stops for a second and then continues again.
WAV - continuous scratchy noise.
M4A - would not play if ~200 Mb or more.
All these files play fine on my computer.
It's a pity because to be able to play these files was the only reason to install Rockbox.
Also, surprisingly, Rockbox proved to be MUCH slower than the original firmware and very buggy. It hangs a dozen times a day.
Are there any patches or fixes I didn't notice?
