Upsampling on BBB

I have beaglebone black with Volumio 1.55 on it. It is strange, but I can not do resampling without constant freezes of sound both through HDMI soundcard (called as Black in UI) and WaveIO (it is USB-I2S card). Even with 24/96 I am getting the worse sound. Actually I get smooth sound only with disabled option of resampling. What is wrong, help please?

p.s. I am talking about upsampling of 16/44 to 24/96 for webradio for example (but with flac file coded in 16/44 the same problem)
