SanDisk e250 fail play FLAC files

[TomecekGD]

Hi.

I have SanDisk e250 v1 with Rockbox 3.7.1. Sometimes when I play FLAC file Rockbox hangs on playback. What I mean "hang on"? For example FLAC file has 10 minutes. First 3 minutes play correctly and suddenly without warning hang on: It looks as play still the same second. I need to start listening track from the beginning

P.S.

ART theme do not work properly on 3.7.1. Top and bottom bars flashes when using the control wheel. It is my favorite theme
