The music files were ripped from CD and encoded in FLAC compression level 8 (max compression). They played perfectly fine on my PC but on my NDS Lite (running moonshell 2.10), there were occasional skips or short high pitched noises during playback . Freezing sometimes happened when fast forwarding/backwarding a FLAC music file. I've tried the exact same songs in mp3 format (224kbps CBR) and FLAC compression level 5 (the default) and WAV (no compression) and there were none of the problems mentioned above. It seems that Moonshell 2.10 has a problem with music files encoded in FLAC at high compression levels. Is there any workaround for this issue (other than encoding at a lower FLAC compression level)?
