m4a (aac) files with 320 kbps !!

This player could not handle m4a (aac) files with 320 kbps data rates . They became unlistenable When screen goes dark.

I noticed a problem if there is a *really* strong, sustained and deep bass note that the Clip Zip will stutter and the audio slows down but when the note has passed the player seems to recover and “catch up”.  Might be the EQ.

Otherwise, 320kbps AAC .m4a seems to be fine, so far.

I have the same problem and it seems that there’re a lot of guys that suffering from this problem. It must be a bug in firmware.

If you’ll read around the forum here, you’ll find it’s a known issue. SanDisk is working on it.

It’s the aac format combined with the high bitrate. If you can tolerate lowering the bitrate a bit, it should work, at present, without issue. (And yep, a bug being worked on.)
