Cambridge Audio DacMagic 100 on Raspb 2

Hi all!

First of all sorry for my bad english…

Well I already was the happy owner of a Cambridge Audio DacMagic 100 USB audio Card. It worked really fine on XBMC but my old Rasp 1 was too slow with HD audio so I bought a Raspberry Pi 2. I installed the latest version of OSMC. The DAC seems to be recognized (I saw ALSA AUDIO USB Analog in the parameters) but… when I try to play a song it simply freeze (not the rasp, the song…)

Could someone help me to find a workaround ?
