Clicking niose with som FLAC files

I’m using a SB X-Fi Surround 5.1(USB) with the Rasp Pi and have clicking noise on FLAC files with 16Bit/44.1kHz. FLAC files with 24Bit/96kHz as well as WAV and MP3 play without any noise! And of course both types of FLAC files doesn’t have noise when played on a PC.

Does anyone have an idea on this?
